5 guestfish - the libguestfs Filesystem Interactive SHell
9 guestfish [--options] [commands]
13 guestfish [--ro|--rw] -a disk.img
15 guestfish [--ro|--rw] -a disk.img -m dev[:mountpoint]
17 guestfish -d libvirt-domain
19 guestfish [--ro|--rw] -a disk.img -i
21 guestfish -d libvirt-domain -i
25 Using guestfish in read/write mode on live virtual machines can be
26 dangerous, potentially causing disk corruption. Use the I<--ro>
27 (read-only) option to use guestfish safely if the disk image or
28 virtual machine might be live.
32 Guestfish is a shell and command-line tool for examining and modifying
33 virtual machine filesystems. It uses libguestfs and exposes all of
34 the functionality of the guestfs API, see L<guestfs(3)>.
36 Guestfish gives you structured access to the libguestfs API, from
37 shell scripts or the command line or interactively. If you want to
38 rescue a broken virtual machine image, you should look at the
39 L<virt-rescue(1)> command.
43 =head2 As an interactive shell
47 Welcome to guestfish, the libguestfs filesystem interactive shell for
48 editing virtual machine filesystems.
50 Type: 'help' for a list of commands
51 'man' to read the manual
52 'quit' to quit the shell
56 ><fs> list-filesystems
58 /dev/vg_guest/lv_root: ext4
59 /dev/vg_guest/lv_swap: swap
60 ><fs> mount /dev/vg_guest/lv_root /
67 =head2 From shell scripts
69 Create a new C</etc/motd> file in a guest or disk image:
74 mount /dev/vg_guest/lv_root /
75 write /etc/motd "Welcome, new users"
78 List the LVM logical volumes in a disk image:
80 guestfish -a disk.img --ro <<_EOF_
85 List all the filesystems in a disk image:
87 guestfish -a disk.img --ro <<_EOF_
92 =head2 On one command line
94 Update C</etc/resolv.conf> in a guest:
97 add disk.img : run : mount /dev/vg_guest/lv_root / : \
98 write /etc/resolv.conf "nameserver 1.2.3.4"
100 Edit C</boot/grub/grub.conf> interactively:
102 guestfish --rw --add disk.img \
103 --mount /dev/vg_guest/lv_root \
104 --mount /dev/sda1:/boot \
105 edit /boot/grub/grub.conf
107 =head2 Mount disks automatically
109 Use the I<-i> option to automatically mount the
110 disks from a virtual machine:
112 guestfish --ro -a disk.img -i cat /etc/group
114 guestfish --ro -d libvirt-domain -i cat /etc/group
116 Another way to edit C</boot/grub/grub.conf> interactively is:
118 guestfish --rw -a disk.img -i edit /boot/grub/grub.conf
120 =head2 As a script interpreter
122 Create a 100MB disk containing an ext2-formatted partition:
124 #!/usr/bin/guestfish -f
125 sparse test1.img 100M
127 part-disk /dev/sda mbr
130 =head2 Start with a prepared disk
132 An alternate way to create a 100MB disk called C<test1.img> containing
133 a single ext2-formatted partition:
137 To list what is available do:
139 guestfish -N help | less
141 =head2 Remote control
143 eval "`guestfish --listen`"
144 guestfish --remote add-ro disk.img
145 guestfish --remote run
146 guestfish --remote lvs
154 Displays general help on options.
156 =item B<-h> | B<--cmd-help>
158 Lists all available guestfish commands.
160 =item B<-h cmd> | B<--cmd-help cmd>
162 Displays detailed help on a single command C<cmd>.
164 =item B<-a image> | B<--add image>
166 Add a block device or virtual machine image to the shell.
168 The format of the disk image is auto-detected. To override this and
169 force a particular format use the I<--format=..> option.
171 =item B<-c URI> | B<--connect URI>
173 When used in conjunction with the I<-d> option, this specifies
174 the libvirt URI to use. The default is to use the default libvirt
179 If using the I<--listen> option and a csh-like shell, use this option.
180 See section L</REMOTE CONTROL AND CSH> below.
182 =item B<-d libvirt-domain> | B<--domain libvirt-domain>
184 Add disks from the named libvirt domain. If the I<--ro> option is
185 also used, then any libvirt domain can be used. However in write
186 mode, only libvirt domains which are shut down can be named here.
188 =item B<-D> | B<--no-dest-paths>
190 Don't tab-complete paths on the guest filesystem. It is useful to be
191 able to hit the tab key to complete paths on the guest filesystem, but
192 this causes extra "hidden" guestfs calls to be made, so this option is
193 here to allow this feature to be disabled.
197 When prompting for keys and passphrases, guestfish normally turns
198 echoing off so you cannot see what you are typing. If you are not
199 worried about Tempest attacks and there is no one else in the room
200 you can specify this flag to see what you are typing.
202 =item B<-f file> | B<--file file>
204 Read commands from C<file>. To write pure guestfish
207 #!/usr/bin/guestfish -f
209 =item B<--format=raw|qcow2|..> | B<--format>
211 The default for the I<-a> option is to auto-detect the format of the
212 disk image. Using this forces the disk format for I<-a> options which
213 follow on the command line. Using I<--format> with no argument
214 switches back to auto-detection for subsequent I<-a> options.
218 guestfish --format=raw -a disk.img
220 forces raw format (no auto-detection) for C<disk.img>.
222 guestfish --format=raw -a disk.img --format -a another.img
224 forces raw format (no auto-detection) for C<disk.img> and reverts to
225 auto-detection for C<another.img>.
227 If you have untrusted raw-format guest disk images, you should use
228 this option to specify the disk format. This avoids a possible
229 security problem with malicious guests (CVE-2010-3851). See also
232 =item B<-i> | B<--inspector>
234 Using L<virt-inspector(1)> code, inspect the disks looking for
235 an operating system and mount filesystems as they would be
236 mounted on the real virtual machine.
238 Typical usage is either:
240 guestfish -d myguest -i
242 (for an inactive libvirt domain called I<myguest>), or:
244 guestfish --ro -d myguest -i
246 (for active domains, readonly), or specify the block device directly:
248 guestfish --rw -a /dev/Guests/MyGuest -i
250 Note that the command line syntax changed slightly over older
251 versions of guestfish. You can still use the old syntax:
253 guestfish [--ro] -i disk.img
255 guestfish [--ro] -i libvirt-domain
257 =item B<--keys-from-stdin>
259 Read key or passphrase parameters from stdin. The default is
260 to try to read passphrases from the user by opening C</dev/tty>.
264 Fork into the background and listen for remote commands. See section
265 L</REMOTE CONTROL GUESTFISH OVER A SOCKET> below.
267 =item B<-m dev[:mountpoint]> | B<--mount dev[:mountpoint]>
269 Mount the named partition or logical volume on the given mountpoint.
271 If the mountpoint is omitted, it defaults to C</>.
273 You have to mount something on C</> before most commands will work.
275 If any I<-m> or I<--mount> options are given, the guest is
276 automatically launched.
278 If you don't know what filesystems a disk image contains, you can
279 either run guestfish without this option, then list the partitions,
280 filesystems and LVs available (see L</list-partitions>,
281 L</list-filesystems> and L</lvs> commands), or you can use the
282 L<virt-filesystems(1)> program.
284 =item B<-n> | B<--no-sync>
286 Disable autosync. This is enabled by default. See the discussion
287 of autosync in the L<guestfs(3)> manpage.
289 =item B<-N type> | B<--new type> | B<-N help>
291 Prepare a fresh disk image formatted as "type". This is an
292 alternative to the I<-a> option: whereas I<-a> adds an existing disk,
293 I<-N> creates a preformatted disk with a filesystem and adds it.
294 See L</PREPARED DISK IMAGES> below.
296 =item B<--progress-bars>
298 Enable progress bars, even when guestfish is used non-interactively.
300 Progress bars are enabled by default when guestfish is used as an
303 =item B<--no-progress-bars>
305 Disable progress bars.
307 =item B<--remote[=pid]>
309 Send remote commands to C<$GUESTFISH_PID> or C<pid>. See section
310 L</REMOTE CONTROL GUESTFISH OVER A SOCKET> below.
312 =item B<-r> | B<--ro>
314 This changes the I<-a> and I<-m> options so that disks are added and
315 mounts are done read-only (see L<guestfs(3)/guestfs_mount_ro>).
317 The option must always be used if the disk image or virtual machine
318 might be running, and is generally recommended in cases where you
319 don't need write access to the disk.
321 Note that prepared disk images created with I<-N> are not affected by
324 See also L</OPENING DISKS FOR READ AND WRITE> below.
328 Enable SELinux support for the guest. See L<guestfs(3)/SELINUX>.
330 =item B<-v> | B<--verbose>
332 Enable very verbose messages. This is particularly useful if you find
335 =item B<-V> | B<--version>
337 Display the guestfish / libguestfs version number and exit.
339 =item B<-w> | B<--rw>
341 This option does nothing at the moment.
342 See L</OPENING DISKS FOR READ AND WRITE> below.
346 Echo each command before executing it.
350 =head1 COMMANDS ON COMMAND LINE
352 Any additional (non-option) arguments are treated as commands to
355 Commands to execute should be separated by a colon (C<:>), where the
356 colon is a separate parameter. Thus:
358 guestfish cmd [args...] : cmd [args...] : cmd [args...] ...
360 If there are no additional arguments, then we enter a shell, either an
361 interactive shell with a prompt (if the input is a terminal) or a
362 non-interactive shell.
364 In either command line mode or non-interactive shell, the first
365 command that gives an error causes the whole shell to exit. In
366 interactive mode (with a prompt) if a command fails, you can continue
369 =head1 USING launch (OR run)
371 As with L<guestfs(3)>, you must first configure your guest by adding
372 disks, then launch it, then mount any disks you need, and finally
373 issue actions/commands. So the general order of the day is:
395 C<run> is a synonym for C<launch>. You must C<launch> (or C<run>)
396 your guest before mounting or performing any other commands.
398 The only exception is that if any of the I<-i>, I<-m>, I<--mount>,
399 I<-N> or I<--new> options were given then C<run> is done
400 automatically, simply because guestfish can't perform the action you
401 asked for without doing this.
403 =head1 OPENING DISKS FOR READ AND WRITE
405 The guestfish (and L<guestmount(1)>) options I<--ro> and I<--rw>
406 affect whether the other command line options I<-a>, I<-c>, I<-d>,
407 I<-i> and I<-m> open disk images read-only or for writing.
409 In libguestfs E<lt> 1.6.2, guestfish and guestmount defaulted to
410 opening disk images supplied on the command line for write. To open a
411 disk image read-only you have to do I<-a image --ro>.
413 This matters: If you accidentally open a live VM disk image writable
414 then you will cause irreversible disk corruption.
416 By libguestfs 1.8 we intend to change the default the other way. Disk
417 images will be opened read-only. You will have to either specify
418 I<guestfish --rw> or change a configuration file in order to get write
419 access for disk images specified by those other command line options.
421 This version of guestfish has a I<--rw> option which does nothing (it
422 is already the default). However it is highly recommended that you
423 use this option to indicate that guestfish needs write access, and to
424 prepare your scripts for the day when this option will be required for
427 B<Note:> This does I<not> affect commands like L</add> and L</mount>,
428 or any other libguestfs program apart from guestfish and guestmount.
432 You can quote ordinary parameters using either single or double
435 add "file with a space.img"
441 A few commands require a list of strings to be passed. For these, use
442 a whitespace-separated list, enclosed in quotes. Strings containing whitespace
443 to be passed through must be enclosed in single quotes. A literal single quote
444 must be escaped with a backslash.
446 vgcreate VG "/dev/sda1 /dev/sdb1"
447 command "/bin/echo 'foo bar'"
448 command "/bin/echo \'foo\'"
450 =head1 OPTIONAL ARGUMENTS
452 Some commands take optional arguments. These arguments appear in this
453 documentation as C<[argname:..]>. You can use them as in these
456 add-drive-opts filename
458 add-drive-opts filename readonly:true
460 add-drive-opts filename format:qcow2 readonly:false
462 Each optional argument can appear at most once. All optional
463 arguments must appear after the required ones.
467 This section applies to all commands which can take integers
472 When the command takes a parameter measured in bytes, you can use one
473 of the following suffixes to specify kilobytes, megabytes and larger
478 =item B<k> or B<K> or B<KiB>
480 The size in kilobytes (multiplied by 1024).
484 The size in SI 1000 byte units.
488 The size in megabytes (multiplied by 1048576).
492 The size in SI 1000000 byte units.
496 The size in gigabytes (multiplied by 2**30).
500 The size in SI 10**9 byte units.
504 The size in terabytes (multiplied by 2**40).
508 The size in SI 10**12 byte units.
512 The size in petabytes (multiplied by 2**50).
516 The size in SI 10**15 byte units.
520 The size in exabytes (multiplied by 2**60).
524 The size in SI 10**18 byte units.
528 The size in zettabytes (multiplied by 2**70).
532 The size in SI 10**21 byte units.
536 The size in yottabytes (multiplied by 2**80).
540 The size in SI 10**24 byte units.
546 truncate-size /file 1G
548 would truncate the file to 1 gigabyte.
550 Be careful because a few commands take sizes in kilobytes or megabytes
551 (eg. the parameter to L</memsize> is specified in megabytes already).
552 Adding a suffix will probably not do what you expect.
554 =head2 OCTAL AND HEXADECIMAL NUMBERS
556 For specifying the radix (base) use the C convention: C<0> to prefix
557 an octal number or C<0x> to prefix a hexadecimal number. For example:
559 1234 decimal number 1234
560 02322 octal number, equivalent to decimal 1234
561 0x4d2 hexadecimal number, equivalent to decimal 1234
563 When using the C<chmod> command, you almost always want to specify an
564 octal number for the mode, and you must prefix it with C<0> (unlike
565 the Unix L<chmod(1)> program):
567 chmod 0777 /public # OK
568 chmod 777 /public # WRONG! This is mode 777 decimal = 01411 octal.
570 Commands that return numbers usually print them in decimal, but
571 some commands print numbers in other radices (eg. C<umask> prints
572 the mode in octal, preceeded by C<0>).
574 =head1 WILDCARDS AND GLOBBING
576 Neither guestfish nor the underlying guestfs API performs
577 wildcard expansion (globbing) by default. So for example the
578 following will not do what you expect:
582 Assuming you don't have a directory called literally C</home/*>
583 then the above command will return an error.
585 To perform wildcard expansion, use the C<glob> command.
589 runs C<rm-rf> on each path that matches (ie. potentially running
590 the command many times), equivalent to:
596 C<glob> only works on simple guest paths and not on device names.
598 If you have several parameters, each containing a wildcard, then glob
599 will perform a Cartesian product.
603 Any line which starts with a I<#> character is treated as a comment
604 and ignored. The I<#> can optionally be preceeded by whitespace,
605 but B<not> by a command. For example:
611 Blank lines are also ignored.
613 =head1 RUNNING COMMANDS LOCALLY
615 Any line which starts with a I<!> character is treated as a command
616 sent to the local shell (C</bin/sh> or whatever L<system(3)> uses).
620 tgz-out /remote local/remote-data.tar.gz
622 will create a directory C<local> on the host, and then export
623 the contents of C</remote> on the mounted filesystem to
624 C<local/remote-data.tar.gz>. (See C<tgz-out>).
626 To change the local directory, use the C<lcd> command. C<!cd> will
627 have no effect, due to the way that subprocesses work in Unix.
631 Use C<command E<lt>spaceE<gt> | command> to pipe the output of the
632 first command (a guestfish command) to the second command (any host
633 command). For example:
635 cat /etc/passwd | awk -F: '$3 == 0 { print }'
637 (where C<cat> is the guestfish cat command, but C<awk> is the host awk
638 program). The above command would list all accounts in the guest
639 filesystem which have UID 0, ie. root accounts including backdoors.
642 hexdump /bin/ls | head
643 list-devices | tail -1
644 tgz-out / - | tar ztf -
646 The space before the pipe symbol is required, any space after the pipe
647 symbol is optional. Everything after the pipe symbol is just passed
648 straight to the host shell, so it can contain redirections, globs and
649 anything else that makes sense on the host side.
651 To use a literal argument which begins with a pipe symbol, you have
656 =head1 HOME DIRECTORIES
658 If a parameter starts with the character C<~> then the tilde may be
659 expanded as a home directory path (either C<~> for the current user's
660 home directory, or C<~user> for another user).
662 Note that home directory expansion happens for users known I<on the
663 host>, not in the guest filesystem.
665 To use a literal argument which begins with a tilde, you have to quote
670 =head1 ENCRYPTED DISKS
672 Libguestfs has some support for Linux guests encrypted according to
673 the Linux Unified Key Setup (LUKS) standard, which includes nearly all
674 whole disk encryption systems used by modern Linux guests. Currently
675 only LVM-on-LUKS is supported.
677 Identify encrypted block devices and partitions using L</vfs-type>:
679 ><fs> vfs-type /dev/sda2
682 Then open those devices using L</luks-open>. This creates a
683 device-mapper device called C</dev/mapper/luksdev>.
685 ><fs> luks-open /dev/sda2 luksdev
686 Enter key or passphrase ("key"): <enter the passphrase>
688 Finally you have to tell LVM to scan for volume groups on
689 the newly created mapper device:
694 The logical volume(s) can now be mounted in the usual way.
696 Before closing a LUKS device you must unmount any logical volumes on
697 it and deactivate the volume groups by calling C<vg-activate false VG>
698 on each one. Then you can close the mapper device:
700 vg-activate false /dev/VG
701 luks-close /dev/mapper/luksdev
705 If a path is prefixed with C<win:> then you can use Windows-style
706 paths (with some limitations). The following commands are equivalent:
708 file /WINDOWS/system32/config/system.LOG
710 file win:/windows/system32/config/system.log
712 file win:\windows\system32\config\system.log
714 file WIN:C:\Windows\SYSTEM32\conFIG\SYSTEM.LOG
716 This syntax implicitly calls C<case-sensitive-path> (q.v.) so it also
717 handles case insensitivity like Windows would. This only works in
718 argument positions that expect a path.
720 =head1 UPLOADING AND DOWNLOADING FILES
722 For commands such as C<upload>, C<download>, C<tar-in>, C<tar-out> and
723 others which upload from or download to a local file, you can use the
724 special filename C<-> to mean "from stdin" or "to stdout". For example:
728 reads stdin and creates from that a file C</foo> in the disk image,
731 tar-out /etc - | tar tf -
733 writes the tarball to stdout and then pipes that into the external
734 "tar" command (see L</PIPES>).
736 When using C<-> to read from stdin, the input is read up to the end of
737 stdin. You can also use a special "heredoc"-like syntax to read up to
738 some arbitrary end marker:
746 Any string of characters can be used instead of C<END>. The end
747 marker must appear on a line of its own, without any preceeding or
748 following characters (not even spaces).
750 Note that the C<-E<lt>E<lt>> syntax only applies to parameters used to
751 upload local files (so-called "FileIn" parameters in the generator).
753 =head1 EXIT ON ERROR BEHAVIOUR
755 By default, guestfish will ignore any errors when in interactive mode
756 (ie. taking commands from a human over a tty), and will exit on the
757 first error in non-interactive mode (scripts, commands given on the
760 If you prefix a command with a I<-> character, then that command will
761 not cause guestfish to exit, even if that (one) command returns an
764 =head1 REMOTE CONTROL GUESTFISH OVER A SOCKET
766 Guestfish can be remote-controlled over a socket. This is useful
767 particularly in shell scripts where you want to make several different
768 changes to a filesystem, but you don't want the overhead of starting
769 up a guestfish process each time.
771 Start a guestfish server process using:
773 eval "`guestfish --listen`"
775 and then send it commands by doing:
777 guestfish --remote cmd [...]
779 To cause the server to exit, send it the exit command:
781 guestfish --remote exit
783 Note that the server will normally exit if there is an error in a
784 command. You can change this in the usual way. See section
785 L</EXIT ON ERROR BEHAVIOUR>.
787 =head2 CONTROLLING MULTIPLE GUESTFISH PROCESSES
789 The C<eval> statement sets the environment variable C<$GUESTFISH_PID>,
790 which is how the I<--remote> option knows where to send the commands.
791 You can have several guestfish listener processes running using:
793 eval "`guestfish --listen`"
795 eval "`guestfish --listen`"
798 guestfish --remote=$pid1 cmd
799 guestfish --remote=$pid2 cmd
801 =head2 REMOTE CONTROL AND CSH
803 When using csh-like shells (csh, tcsh etc) you have to add the
806 eval "`guestfish --listen --csh`"
808 =head2 REMOTE CONTROL DETAILS
810 Remote control happens over a Unix domain socket called
811 C</tmp/.guestfish-$UID/socket-$PID>, where C<$UID> is the effective
812 user ID of the process, and C<$PID> is the process ID of the server.
814 Guestfish client and server versions must match exactly.
816 =head1 PREPARED DISK IMAGES
818 Use the I<-N type> or I<--new type> parameter to select one of a set
819 of preformatted disk images that guestfish can make for you to save
820 typing. This is particularly useful for testing purposes. This
821 option is used instead of the I<-a> option, and like I<-a> can appear
822 multiple times (and can be mixed with I<-a>).
824 The new disk is called C<test1.img> for the first I<-N>, C<test2.img>
825 for the second and so on. Existing files in the current directory are
828 The type briefly describes how the disk should be sized, partitioned,
829 how filesystem(s) should be created, and how content should be added.
830 Optionally the type can be followed by extra parameters, separated by
831 C<:> (colon) characters. For example, I<-N fs> creates a default
832 100MB, sparsely-allocated disk, containing a single partition, with
833 the partition formatted as ext2. I<-N fs:ext4:1G> is the same, but
834 for an ext4 filesystem on a 1GB disk instead.
836 To list the available types and any extra parameters they take, run:
838 guestfish -N help | less
840 Note that the prepared filesystem is not mounted. You would usually
841 have to use the C<mount /dev/sda1 /> command or add the
842 I<-m /dev/sda1> option.
844 If any I<-N> or I<--new> options are given, the guest is automatically
849 Create a 100MB disk with an ext4-formatted partition:
853 Create a 32MB disk with a VFAT-formatted partition, and mount it:
855 guestfish -N fs:vfat:32M -m /dev/sda1
857 Create a blank 200MB disk:
859 guestfish -N disk:200M
863 Some (not all) long-running commands send progress notification
864 messages as they are running. Guestfish turns these messages into
867 When a command that supports progress bars takes longer than two
868 seconds to run, and if progress bars are enabled, then you will see
869 one appearing below the command:
871 ><fs> copy-size /large-file /another-file 2048M
872 / 10% [#####-----------------------------------------] 00:30
874 The spinner on the left hand side moves round once for every progress
875 notification received from the backend. This is a (reasonably) golden
876 assurance that the command is "doing something" even if the progress
877 bar is not moving, because the command is able to send the progress
878 notifications. When the bar reaches 100% and the command finishes,
879 the spinner disappears.
881 Progress bars are enabled by default when guestfish is used
882 interactively. You can enable them even for non-interactive modes
883 using I<--progress-bars>, and you can disable them completely using
884 I<--no-progress-bars>.
886 =head1 GUESTFISH COMMANDS
888 The commands in this section are guestfish convenience commands, in
889 other words, they are not part of the L<guestfs(3)> API.
896 Without any parameter, this provides general help.
898 With a C<cmd> parameter, this displays detailed help for that command.
902 This exits guestfish. You can also use C<^D> key.
912 guestfish returns 0 if the commands completed without error, or
913 1 if there was an error.
915 =head1 ENVIRONMENT VARIABLES
921 The C<edit> command uses C<$EDITOR> as the editor. If not
926 Used with the I<--remote> option to specify the remote guestfish
927 process to control. See section
928 L</REMOTE CONTROL GUESTFISH OVER A SOCKET>.
932 The L</hexedit> command uses C<$HEXEDITOR> as the external hex
933 editor. If not specified, the external L<hexedit(1)> program
938 If compiled with GNU readline support, various files in the
939 home directory can be used. See L</FILES>.
941 =item LIBGUESTFS_APPEND
943 Pass additional options to the guest kernel.
945 =item LIBGUESTFS_DEBUG
947 Set C<LIBGUESTFS_DEBUG=1> to enable verbose messages. This has the
948 same effect as using the B<-v> option.
950 =item LIBGUESTFS_MEMSIZE
952 Set the memory allocated to the qemu process, in megabytes. For
955 LIBGUESTFS_MEMSIZE=700
957 =item LIBGUESTFS_PATH
959 Set the path that guestfish uses to search for kernel and initrd.img.
960 See the discussion of paths in L<guestfs(3)>.
962 =item LIBGUESTFS_QEMU
964 Set the default qemu binary that libguestfs uses. If not set, then
965 the qemu which was found at compile time by the configure script is
968 =item LIBGUESTFS_TRACE
970 Set C<LIBGUESTFS_TRACE=1> to enable command traces.
974 The C<more> command uses C<$PAGER> as the pager. If not
975 set, it uses C<more>.
979 Location of temporary directory, defaults to C</tmp>.
981 If libguestfs was compiled to use the supermin appliance then the
982 real appliance is cached in this directory, shared between all
983 handles belonging to the same EUID. You can use C<$TMPDIR> to
984 configure another directory to use in case C</tmp> is not large
993 =item $HOME/.guestfish
995 If compiled with GNU readline support, then the command history
996 is saved in this file.
1002 If compiled with GNU readline support, then these files can be used to
1003 configure readline. For further information, please see
1004 L<readline(3)/INITIALIZATION FILE>.
1006 To write rules which only apply to guestfish, use:
1012 Variables that you can set in inputrc that change the behaviour
1013 of guestfish in useful ways include:
1017 =item completion-ignore-case (default: on)
1019 By default, guestfish will ignore case when tab-completing
1020 paths on the disk. Use:
1022 set completion-ignore-case off
1024 to make guestfish case sensitive.
1030 =item test2.img (etc)
1032 When using the C<-N> or C<--new> option, the prepared disk or
1033 filesystem will be created in the file C<test1.img> in the current
1034 directory. The second use of C<-N> will use C<test2.img> and so on.
1035 Any existing file with the same name will be overwritten.
