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
279 can either run guestfish without this option, then list the partitions
280 and LVs available (see L</list-partitions> and L</lvs> commands),
281 or you can use the L<virt-list-filesystems(1)> program.
283 =item B<-n> | B<--no-sync>
285 Disable autosync. This is enabled by default. See the discussion
286 of autosync in the L<guestfs(3)> manpage.
288 =item B<-N type> | B<--new type> | B<-N help>
290 Prepare a fresh disk image formatted as "type". This is an
291 alternative to the I<-a> option: whereas I<-a> adds an existing disk,
292 I<-N> creates a preformatted disk with a filesystem and adds it.
293 See L</PREPARED DISK IMAGES> below.
295 =item B<--progress-bars>
297 Enable progress bars, even when guestfish is used non-interactively.
299 Progress bars are enabled by default when guestfish is used as an
302 =item B<--no-progress-bars>
304 Disable progress bars.
306 =item B<--remote[=pid]>
308 Send remote commands to C<$GUESTFISH_PID> or C<pid>. See section
309 L</REMOTE CONTROL GUESTFISH OVER A SOCKET> below.
311 =item B<-r> | B<--ro>
313 This changes the I<-a> and I<-m> options so that disks are added and
314 mounts are done read-only (see L<guestfs(3)/guestfs_mount_ro>).
316 The option must always be used if the disk image or virtual machine
317 might be running, and is generally recommended in cases where you
318 don't need write access to the disk.
320 Note that prepared disk images created with I<-N> are not affected by
323 See also L</OPENING DISKS FOR READ AND WRITE> below.
327 Enable SELinux support for the guest. See L<guestfs(3)/SELINUX>.
329 =item B<-v> | B<--verbose>
331 Enable very verbose messages. This is particularly useful if you find
334 =item B<-V> | B<--version>
336 Display the guestfish / libguestfs version number and exit.
338 =item B<-w> | B<--rw>
340 This option does nothing at the moment.
341 See L</OPENING DISKS FOR READ AND WRITE> below.
345 Echo each command before executing it.
349 =head1 COMMANDS ON COMMAND LINE
351 Any additional (non-option) arguments are treated as commands to
354 Commands to execute should be separated by a colon (C<:>), where the
355 colon is a separate parameter. Thus:
357 guestfish cmd [args...] : cmd [args...] : cmd [args...] ...
359 If there are no additional arguments, then we enter a shell, either an
360 interactive shell with a prompt (if the input is a terminal) or a
361 non-interactive shell.
363 In either command line mode or non-interactive shell, the first
364 command that gives an error causes the whole shell to exit. In
365 interactive mode (with a prompt) if a command fails, you can continue
368 =head1 USING launch (OR run)
370 As with L<guestfs(3)>, you must first configure your guest by adding
371 disks, then launch it, then mount any disks you need, and finally
372 issue actions/commands. So the general order of the day is:
394 C<run> is a synonym for C<launch>. You must C<launch> (or C<run>)
395 your guest before mounting or performing any other commands.
397 The only exception is that if any of the I<-i>, I<-m>, I<--mount>,
398 I<-N> or I<--new> options were given then C<run> is done
399 automatically, simply because guestfish can't perform the action you
400 asked for without doing this.
402 =head1 OPENING DISKS FOR READ AND WRITE
404 The guestfish (and L<guestmount(1)>) options I<--ro> and I<--rw>
405 affect whether the other command line options I<-a>, I<-c>, I<-d>,
406 I<-i> and I<-m> open disk images read-only or for writing.
408 In libguestfs E<lt> 1.6.2, guestfish and guestmount defaulted to
409 opening disk images supplied on the command line for write. To open a
410 disk image read-only you have to do I<-a image --ro>.
412 This matters: If you accidentally open a live VM disk image writable
413 then you will cause irreversible disk corruption.
415 By libguestfs 1.8 we intend to change the default the other way. Disk
416 images will be opened read-only. You will have to either specify
417 I<guestfish --rw> or change a configuration file in order to get write
418 access for disk images specified by those other command line options.
420 This version of guestfish has a I<--rw> option which does nothing (it
421 is already the default). However it is highly recommended that you
422 use this option to indicate that guestfish needs write access, and to
423 prepare your scripts for the day when this option will be required for
426 B<Note:> This does I<not> affect commands like L</add> and L</mount>,
427 or any other libguestfs program apart from guestfish and guestmount.
431 You can quote ordinary parameters using either single or double
434 add "file with a space.img"
440 A few commands require a list of strings to be passed. For these, use
441 a whitespace-separated list, enclosed in quotes. Strings containing whitespace
442 to be passed through must be enclosed in single quotes. A literal single quote
443 must be escaped with a backslash.
445 vgcreate VG "/dev/sda1 /dev/sdb1"
446 command "/bin/echo 'foo bar'"
447 command "/bin/echo \'foo\'"
449 =head1 OPTIONAL ARGUMENTS
451 Some commands take optional arguments. These arguments appear in this
452 documentation as C<[argname:..]>. You can use them as in these
455 add-drive-opts filename
457 add-drive-opts filename readonly:true
459 add-drive-opts filename format:qcow2 readonly:false
461 Each optional argument can appear at most once. All optional
462 arguments must appear after the required ones.
466 This section applies to all commands which can take integers
471 When the command takes a parameter measured in bytes, you can use one
472 of the following suffixes to specify kilobytes, megabytes and larger
477 =item B<k> or B<K> or B<KiB>
479 The size in kilobytes (multiplied by 1024).
483 The size in SI 1000 byte units.
487 The size in megabytes (multiplied by 1048576).
491 The size in SI 1000000 byte units.
495 The size in gigabytes (multiplied by 2**30).
499 The size in SI 10**9 byte units.
503 The size in terabytes (multiplied by 2**40).
507 The size in SI 10**12 byte units.
511 The size in petabytes (multiplied by 2**50).
515 The size in SI 10**15 byte units.
519 The size in exabytes (multiplied by 2**60).
523 The size in SI 10**18 byte units.
527 The size in zettabytes (multiplied by 2**70).
531 The size in SI 10**21 byte units.
535 The size in yottabytes (multiplied by 2**80).
539 The size in SI 10**24 byte units.
545 truncate-size /file 1G
547 would truncate the file to 1 gigabyte.
549 Be careful because a few commands take sizes in kilobytes or megabytes
550 (eg. the parameter to L</memsize> is specified in megabytes already).
551 Adding a suffix will probably not do what you expect.
553 =head2 OCTAL AND HEXADECIMAL NUMBERS
555 For specifying the radix (base) use the C convention: C<0> to prefix
556 an octal number or C<0x> to prefix a hexadecimal number. For example:
558 1234 decimal number 1234
559 02322 octal number, equivalent to decimal 1234
560 0x4d2 hexadecimal number, equivalent to decimal 1234
562 When using the C<chmod> command, you almost always want to specify an
563 octal number for the mode, and you must prefix it with C<0> (unlike
564 the Unix L<chmod(1)> program):
566 chmod 0777 /public # OK
567 chmod 777 /public # WRONG! This is mode 777 decimal = 01411 octal.
569 Commands that return numbers usually print them in decimal, but
570 some commands print numbers in other radices (eg. C<umask> prints
571 the mode in octal, preceeded by C<0>).
573 =head1 WILDCARDS AND GLOBBING
575 Neither guestfish nor the underlying guestfs API performs
576 wildcard expansion (globbing) by default. So for example the
577 following will not do what you expect:
581 Assuming you don't have a directory called literally C</home/*>
582 then the above command will return an error.
584 To perform wildcard expansion, use the C<glob> command.
588 runs C<rm-rf> on each path that matches (ie. potentially running
589 the command many times), equivalent to:
595 C<glob> only works on simple guest paths and not on device names.
597 If you have several parameters, each containing a wildcard, then glob
598 will perform a Cartesian product.
602 Any line which starts with a I<#> character is treated as a comment
603 and ignored. The I<#> can optionally be preceeded by whitespace,
604 but B<not> by a command. For example:
610 Blank lines are also ignored.
612 =head1 RUNNING COMMANDS LOCALLY
614 Any line which starts with a I<!> character is treated as a command
615 sent to the local shell (C</bin/sh> or whatever L<system(3)> uses).
619 tgz-out /remote local/remote-data.tar.gz
621 will create a directory C<local> on the host, and then export
622 the contents of C</remote> on the mounted filesystem to
623 C<local/remote-data.tar.gz>. (See C<tgz-out>).
625 To change the local directory, use the C<lcd> command. C<!cd> will
626 have no effect, due to the way that subprocesses work in Unix.
630 Use C<command E<lt>spaceE<gt> | command> to pipe the output of the
631 first command (a guestfish command) to the second command (any host
632 command). For example:
634 cat /etc/passwd | awk -F: '$3 == 0 { print }'
636 (where C<cat> is the guestfish cat command, but C<awk> is the host awk
637 program). The above command would list all accounts in the guest
638 filesystem which have UID 0, ie. root accounts including backdoors.
641 hexdump /bin/ls | head
642 list-devices | tail -1
643 tgz-out / - | tar ztf -
645 The space before the pipe symbol is required, any space after the pipe
646 symbol is optional. Everything after the pipe symbol is just passed
647 straight to the host shell, so it can contain redirections, globs and
648 anything else that makes sense on the host side.
650 To use a literal argument which begins with a pipe symbol, you have
655 =head1 HOME DIRECTORIES
657 If a parameter starts with the character C<~> then the tilde may be
658 expanded as a home directory path (either C<~> for the current user's
659 home directory, or C<~user> for another user).
661 Note that home directory expansion happens for users known I<on the
662 host>, not in the guest filesystem.
664 To use a literal argument which begins with a tilde, you have to quote
669 =head1 ENCRYPTED DISKS
671 Libguestfs has some support for Linux guests encrypted according to
672 the Linux Unified Key Setup (LUKS) standard, which includes nearly all
673 whole disk encryption systems used by modern Linux guests. Currently
674 only LVM-on-LUKS is supported.
676 Identify encrypted block devices and partitions using L</vfs-type>:
678 ><fs> vfs-type /dev/sda2
681 Then open those devices using L</luks-open>. This creates a
682 device-mapper device called C</dev/mapper/luksdev>.
684 ><fs> luks-open /dev/sda2 luksdev
685 Enter key or passphrase ("key"): <enter the passphrase>
687 Finally you have to tell LVM to scan for volume groups on
688 the newly created mapper device:
693 The logical volume(s) can now be mounted in the usual way.
695 Before closing a LUKS device you must unmount any logical volumes on
696 it and deactivate the volume groups by calling C<vg-activate false VG>
697 on each one. Then you can close the mapper device:
699 vg-activate false /dev/VG
700 luks-close /dev/mapper/luksdev
704 If a path is prefixed with C<win:> then you can use Windows-style
705 paths (with some limitations). The following commands are equivalent:
707 file /WINDOWS/system32/config/system.LOG
709 file win:/windows/system32/config/system.log
711 file win:\windows\system32\config\system.log
713 file WIN:C:\Windows\SYSTEM32\conFIG\SYSTEM.LOG
715 This syntax implicitly calls C<case-sensitive-path> (q.v.) so it also
716 handles case insensitivity like Windows would. This only works in
717 argument positions that expect a path.
719 =head1 UPLOADING AND DOWNLOADING FILES
721 For commands such as C<upload>, C<download>, C<tar-in>, C<tar-out> and
722 others which upload from or download to a local file, you can use the
723 special filename C<-> to mean "from stdin" or "to stdout". For example:
727 reads stdin and creates from that a file C</foo> in the disk image,
730 tar-out /etc - | tar tf -
732 writes the tarball to stdout and then pipes that into the external
733 "tar" command (see L</PIPES>).
735 When using C<-> to read from stdin, the input is read up to the end of
736 stdin. You can also use a special "heredoc"-like syntax to read up to
737 some arbitrary end marker:
745 Any string of characters can be used instead of C<END>. The end
746 marker must appear on a line of its own, without any preceeding or
747 following characters (not even spaces).
749 Note that the C<-E<lt>E<lt>> syntax only applies to parameters used to
750 upload local files (so-called "FileIn" parameters in the generator).
752 =head1 EXIT ON ERROR BEHAVIOUR
754 By default, guestfish will ignore any errors when in interactive mode
755 (ie. taking commands from a human over a tty), and will exit on the
756 first error in non-interactive mode (scripts, commands given on the
759 If you prefix a command with a I<-> character, then that command will
760 not cause guestfish to exit, even if that (one) command returns an
763 =head1 REMOTE CONTROL GUESTFISH OVER A SOCKET
765 Guestfish can be remote-controlled over a socket. This is useful
766 particularly in shell scripts where you want to make several different
767 changes to a filesystem, but you don't want the overhead of starting
768 up a guestfish process each time.
770 Start a guestfish server process using:
772 eval "`guestfish --listen`"
774 and then send it commands by doing:
776 guestfish --remote cmd [...]
778 To cause the server to exit, send it the exit command:
780 guestfish --remote exit
782 Note that the server will normally exit if there is an error in a
783 command. You can change this in the usual way. See section
784 L</EXIT ON ERROR BEHAVIOUR>.
786 =head2 CONTROLLING MULTIPLE GUESTFISH PROCESSES
788 The C<eval> statement sets the environment variable C<$GUESTFISH_PID>,
789 which is how the I<--remote> option knows where to send the commands.
790 You can have several guestfish listener processes running using:
792 eval "`guestfish --listen`"
794 eval "`guestfish --listen`"
797 guestfish --remote=$pid1 cmd
798 guestfish --remote=$pid2 cmd
800 =head2 REMOTE CONTROL AND CSH
802 When using csh-like shells (csh, tcsh etc) you have to add the
805 eval "`guestfish --listen --csh`"
807 =head2 REMOTE CONTROL DETAILS
809 Remote control happens over a Unix domain socket called
810 C</tmp/.guestfish-$UID/socket-$PID>, where C<$UID> is the effective
811 user ID of the process, and C<$PID> is the process ID of the server.
813 Guestfish client and server versions must match exactly.
815 =head1 PREPARED DISK IMAGES
817 Use the I<-N type> or I<--new type> parameter to select one of a set
818 of preformatted disk images that guestfish can make for you to save
819 typing. This is particularly useful for testing purposes. This
820 option is used instead of the I<-a> option, and like I<-a> can appear
821 multiple times (and can be mixed with I<-a>).
823 The new disk is called C<test1.img> for the first I<-N>, C<test2.img>
824 for the second and so on. Existing files in the current directory are
827 The type briefly describes how the disk should be sized, partitioned,
828 how filesystem(s) should be created, and how content should be added.
829 Optionally the type can be followed by extra parameters, separated by
830 C<:> (colon) characters. For example, I<-N fs> creates a default
831 100MB, sparsely-allocated disk, containing a single partition, with
832 the partition formatted as ext2. I<-N fs:ext4:1G> is the same, but
833 for an ext4 filesystem on a 1GB disk instead.
835 To list the available types and any extra parameters they take, run:
837 guestfish -N help | less
839 Note that the prepared filesystem is not mounted. You would usually
840 have to use the C<mount /dev/sda1 /> command or add the
841 I<-m /dev/sda1> option.
843 If any I<-N> or I<--new> options are given, the guest is automatically
848 Create a 100MB disk with an ext4-formatted partition:
852 Create a 32MB disk with a VFAT-formatted partition, and mount it:
854 guestfish -N fs:vfat:32M -m /dev/sda1
856 Create a blank 200MB disk:
858 guestfish -N disk:200M
862 Some (not all) long-running commands send progress notification
863 messages as they are running. Guestfish turns these messages into
866 When a command that supports progress bars takes longer than two
867 seconds to run, and if progress bars are enabled, then you will see
868 one appearing below the command:
870 ><fs> copy-size /large-file /another-file 2048M
871 / 10% [#####-----------------------------------------] 00:30
873 The spinner on the left hand side moves round once for every progress
874 notification received from the backend. This is a (reasonably) golden
875 assurance that the command is "doing something" even if the progress
876 bar is not moving, because the command is able to send the progress
877 notifications. When the bar reaches 100% and the command finishes,
878 the spinner disappears.
880 Progress bars are enabled by default when guestfish is used
881 interactively. You can enable them even for non-interactive modes
882 using I<--progress-bars>, and you can disable them completely using
883 I<--no-progress-bars>.
885 =head1 GUESTFISH COMMANDS
887 The commands in this section are guestfish convenience commands, in
888 other words, they are not part of the L<guestfs(3)> API.
895 Without any parameter, this provides general help.
897 With a C<cmd> parameter, this displays detailed help for that command.
901 This exits guestfish. You can also use C<^D> key.
911 guestfish returns 0 if the commands completed without error, or
912 1 if there was an error.
914 =head1 ENVIRONMENT VARIABLES
920 The C<edit> command uses C<$EDITOR> as the editor. If not
925 Used with the I<--remote> option to specify the remote guestfish
926 process to control. See section
927 L</REMOTE CONTROL GUESTFISH OVER A SOCKET>.
931 The L</hexedit> command uses C<$HEXEDITOR> as the external hex
932 editor. If not specified, the external L<hexedit(1)> program
937 If compiled with GNU readline support, various files in the
938 home directory can be used. See L</FILES>.
940 =item LIBGUESTFS_APPEND
942 Pass additional options to the guest kernel.
944 =item LIBGUESTFS_DEBUG
946 Set C<LIBGUESTFS_DEBUG=1> to enable verbose messages. This has the
947 same effect as using the B<-v> option.
949 =item LIBGUESTFS_MEMSIZE
951 Set the memory allocated to the qemu process, in megabytes. For
954 LIBGUESTFS_MEMSIZE=700
956 =item LIBGUESTFS_PATH
958 Set the path that guestfish uses to search for kernel and initrd.img.
959 See the discussion of paths in L<guestfs(3)>.
961 =item LIBGUESTFS_QEMU
963 Set the default qemu binary that libguestfs uses. If not set, then
964 the qemu which was found at compile time by the configure script is
967 =item LIBGUESTFS_TRACE
969 Set C<LIBGUESTFS_TRACE=1> to enable command traces.
973 The C<more> command uses C<$PAGER> as the pager. If not
974 set, it uses C<more>.
978 Location of temporary directory, defaults to C</tmp>.
980 If libguestfs was compiled to use the supermin appliance then the
981 real appliance is cached in this directory, shared between all
982 handles belonging to the same EUID. You can use C<$TMPDIR> to
983 configure another directory to use in case C</tmp> is not large
992 =item $HOME/.guestfish
994 If compiled with GNU readline support, then the command history
995 is saved in this file.
1001 If compiled with GNU readline support, then these files can be used to
1002 configure readline. For further information, please see
1003 L<readline(3)/INITIALIZATION FILE>.
1005 To write rules which only apply to guestfish, use:
1011 Variables that you can set in inputrc that change the behaviour
1012 of guestfish in useful ways include:
1016 =item completion-ignore-case (default: on)
1018 By default, guestfish will ignore case when tab-completing
1019 paths on the disk. Use:
1021 set completion-ignore-case off
1023 to make guestfish case sensitive.
1029 =item test2.img (etc)
1031 When using the C<-N> or C<--new> option, the prepared disk or
1032 filesystem will be created in the file C<test1.img> in the current
1033 directory. The second use of C<-N> will use C<test2.img> and so on.
1034 Any existing file with the same name will be overwritten.
