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
177 =item B<-d libvirt-domain> | B<--domain libvirt-domain>
179 Add disks from the named libvirt domain. If the I<--ro> option is
180 also used, then any libvirt domain can be used. However in write
181 mode, only libvirt domains which are shut down can be named here.
183 =item B<-D> | B<--no-dest-paths>
185 Don't tab-complete paths on the guest filesystem. It is useful to be
186 able to hit the tab key to complete paths on the guest filesystem, but
187 this causes extra "hidden" guestfs calls to be made, so this option is
188 here to allow this feature to be disabled.
192 When prompting for keys and passphrases, guestfish normally turns
193 echoing off so you cannot see what you are typing. If you are not
194 worried about Tempest attacks and there is no one else in the room
195 you can specify this flag to see what you are typing.
197 =item B<-f file> | B<--file file>
199 Read commands from C<file>. To write pure guestfish
202 #!/usr/bin/guestfish -f
204 =item B<--format=raw|qcow2|..> | B<--format>
206 The default for the I<-a> option is to auto-detect the format of the
207 disk image. Using this forces the disk format for I<-a> options which
208 follow on the command line. Using I<--format> with no argument
209 switches back to auto-detection for subsequent I<-a> options.
213 guestfish --format=raw -a disk.img
215 forces raw format (no auto-detection) for C<disk.img>.
217 guestfish --format=raw -a disk.img --format -a another.img
219 forces raw format (no auto-detection) for C<disk.img> and reverts to
220 auto-detection for C<another.img>.
222 If you have untrusted raw-format guest disk images, you should use
223 this option to specify the disk format. This avoids a possible
224 security problem with malicious guests (CVE-2010-3851). See also
227 =item B<-i> | B<--inspector>
229 Using L<virt-inspector(1)> code, inspect the disks looking for
230 an operating system and mount filesystems as they would be
231 mounted on the real virtual machine.
233 Typical usage is either:
235 guestfish -d myguest -i
237 (for an inactive libvirt domain called I<myguest>), or:
239 guestfish --ro -d myguest -i
241 (for active domains, readonly), or specify the block device directly:
243 guestfish --rw -a /dev/Guests/MyGuest -i
245 Note that the command line syntax changed slightly over older
246 versions of guestfish. You can still use the old syntax:
248 guestfish [--ro] -i disk.img
250 guestfish [--ro] -i libvirt-domain
252 =item B<--keys-from-stdin>
254 Read key or passphrase parameters from stdin. The default is
255 to try to read passphrases from the user by opening C</dev/tty>.
259 Fork into the background and listen for remote commands. See section
260 L</REMOTE CONTROL GUESTFISH OVER A SOCKET> below.
262 =item B<-m dev[:mountpoint]> | B<--mount dev[:mountpoint]>
264 Mount the named partition or logical volume on the given mountpoint.
266 If the mountpoint is omitted, it defaults to C</>.
268 You have to mount something on C</> before most commands will work.
270 If any I<-m> or I<--mount> options are given, the guest is
271 automatically launched.
273 If you don't know what filesystems a disk image contains, you
274 can either run guestfish without this option, then list the partitions
275 and LVs available (see L</list-partitions> and L</lvs> commands),
276 or you can use the L<virt-list-filesystems(1)> program.
278 =item B<-n> | B<--no-sync>
280 Disable autosync. This is enabled by default. See the discussion
281 of autosync in the L<guestfs(3)> manpage.
283 =item B<-N type> | B<--new type> | B<-N help>
285 Prepare a fresh disk image formatted as "type". This is an
286 alternative to the I<-a> option: whereas I<-a> adds an existing disk,
287 I<-N> creates a preformatted disk with a filesystem and adds it.
288 See L</PREPARED DISK IMAGES> below.
290 =item B<--progress-bars>
292 Enable progress bars, even when guestfish is used non-interactively.
294 Progress bars are enabled by default when guestfish is used as an
297 =item B<--no-progress-bars>
299 Disable progress bars.
301 =item B<--remote[=pid]>
303 Send remote commands to C<$GUESTFISH_PID> or C<pid>. See section
304 L</REMOTE CONTROL GUESTFISH OVER A SOCKET> below.
306 =item B<-r> | B<--ro>
308 This changes the I<-a> and I<-m> options so that disks are added and
309 mounts are done read-only (see L<guestfs(3)/guestfs_mount_ro>).
311 The option must always be used if the disk image or virtual machine
312 might be running, and is generally recommended in cases where you
313 don't need write access to the disk.
315 Note that prepared disk images created with I<-N> are not affected by
318 See also L</OPENING DISKS FOR READ AND WRITE> below.
322 Enable SELinux support for the guest. See L<guestfs(3)/SELINUX>.
324 =item B<-v> | B<--verbose>
326 Enable very verbose messages. This is particularly useful if you find
329 =item B<-V> | B<--version>
331 Display the guestfish / libguestfs version number and exit.
333 =item B<-w> | B<--rw>
335 This option does nothing at the moment.
336 See L</OPENING DISKS FOR READ AND WRITE> below.
340 Echo each command before executing it.
344 =head1 COMMANDS ON COMMAND LINE
346 Any additional (non-option) arguments are treated as commands to
349 Commands to execute should be separated by a colon (C<:>), where the
350 colon is a separate parameter. Thus:
352 guestfish cmd [args...] : cmd [args...] : cmd [args...] ...
354 If there are no additional arguments, then we enter a shell, either an
355 interactive shell with a prompt (if the input is a terminal) or a
356 non-interactive shell.
358 In either command line mode or non-interactive shell, the first
359 command that gives an error causes the whole shell to exit. In
360 interactive mode (with a prompt) if a command fails, you can continue
363 =head1 USING launch (OR run)
365 As with L<guestfs(3)>, you must first configure your guest by adding
366 disks, then launch it, then mount any disks you need, and finally
367 issue actions/commands. So the general order of the day is:
389 C<run> is a synonym for C<launch>. You must C<launch> (or C<run>)
390 your guest before mounting or performing any other commands.
392 The only exception is that if any of the I<-i>, I<-m>, I<--mount>,
393 I<-N> or I<--new> options were given then C<run> is done
394 automatically, simply because guestfish can't perform the action you
395 asked for without doing this.
397 =head1 OPENING DISKS FOR READ AND WRITE
399 The guestfish (and L<guestmount(1)>) options I<--ro> and I<--rw>
400 affect whether the other command line options I<-a>, I<-c>, I<-d>,
401 I<-i> and I<-m> open disk images read-only or for writing.
403 In libguestfs E<lt> 1.6.2, guestfish and guestmount defaulted to
404 opening disk images supplied on the command line for write. To open a
405 disk image read-only you have to do I<-a image --ro>.
407 This matters: If you accidentally open a live VM disk image writable
408 then you will cause irreversible disk corruption.
410 By libguestfs 1.8 we intend to change the default the other way. Disk
411 images will be opened read-only. You will have to either specify
412 I<guestfish --rw> or change a configuration file in order to get write
413 access for disk images specified by those other command line options.
415 This version of guestfish has a I<--rw> option which does nothing (it
416 is already the default). However it is highly recommended that you
417 use this option to indicate that guestfish needs write access, and to
418 prepare your scripts for the day when this option will be required for
421 B<Note:> This does I<not> affect commands like L</add> and L</mount>,
422 or any other libguestfs program apart from guestfish and guestmount.
426 You can quote ordinary parameters using either single or double
429 add "file with a space.img"
435 A few commands require a list of strings to be passed. For these, use
436 a whitespace-separated list, enclosed in quotes. Strings containing whitespace
437 to be passed through must be enclosed in single quotes. A literal single quote
438 must be escaped with a backslash.
440 vgcreate VG "/dev/sda1 /dev/sdb1"
441 command "/bin/echo 'foo bar'"
442 command "/bin/echo \'foo\'"
444 =head1 OPTIONAL ARGUMENTS
446 Some commands take optional arguments. These arguments appear in this
447 documentation as C<[argname:..]>. You can use them as in these
450 add-drive-opts filename
452 add-drive-opts filename readonly:true
454 add-drive-opts filename format:qcow2 readonly:false
456 Each optional argument can appear at most once. All optional
457 arguments must appear after the required ones.
461 This section applies to all commands which can take integers
466 When the command takes a parameter measured in bytes, you can use one
467 of the following suffixes to specify kilobytes, megabytes and larger
472 =item B<k> or B<K> or B<KiB>
474 The size in kilobytes (multiplied by 1024).
478 The size in SI 1000 byte units.
482 The size in megabytes (multiplied by 1048576).
486 The size in SI 1000000 byte units.
490 The size in gigabytes (multiplied by 2**30).
494 The size in SI 10**9 byte units.
498 The size in terabytes (multiplied by 2**40).
502 The size in SI 10**12 byte units.
506 The size in petabytes (multiplied by 2**50).
510 The size in SI 10**15 byte units.
514 The size in exabytes (multiplied by 2**60).
518 The size in SI 10**18 byte units.
522 The size in zettabytes (multiplied by 2**70).
526 The size in SI 10**21 byte units.
530 The size in yottabytes (multiplied by 2**80).
534 The size in SI 10**24 byte units.
540 truncate-size /file 1G
542 would truncate the file to 1 gigabyte.
544 Be careful because a few commands take sizes in kilobytes or megabytes
545 (eg. the parameter to L</memsize> is specified in megabytes already).
546 Adding a suffix will probably not do what you expect.
548 =head2 OCTAL AND HEXADECIMAL NUMBERS
550 For specifying the radix (base) use the C convention: C<0> to prefix
551 an octal number or C<0x> to prefix a hexadecimal number. For example:
553 1234 decimal number 1234
554 02322 octal number, equivalent to decimal 1234
555 0x4d2 hexadecimal number, equivalent to decimal 1234
557 When using the C<chmod> command, you almost always want to specify an
558 octal number for the mode, and you must prefix it with C<0> (unlike
559 the Unix L<chmod(1)> program):
561 chmod 0777 /public # OK
562 chmod 777 /public # WRONG! This is mode 777 decimal = 01411 octal.
564 Commands that return numbers usually print them in decimal, but
565 some commands print numbers in other radices (eg. C<umask> prints
566 the mode in octal, preceeded by C<0>).
568 =head1 WILDCARDS AND GLOBBING
570 Neither guestfish nor the underlying guestfs API performs
571 wildcard expansion (globbing) by default. So for example the
572 following will not do what you expect:
576 Assuming you don't have a directory called literally C</home/*>
577 then the above command will return an error.
579 To perform wildcard expansion, use the C<glob> command.
583 runs C<rm-rf> on each path that matches (ie. potentially running
584 the command many times), equivalent to:
590 C<glob> only works on simple guest paths and not on device names.
592 If you have several parameters, each containing a wildcard, then glob
593 will perform a Cartesian product.
597 Any line which starts with a I<#> character is treated as a comment
598 and ignored. The I<#> can optionally be preceeded by whitespace,
599 but B<not> by a command. For example:
605 Blank lines are also ignored.
607 =head1 RUNNING COMMANDS LOCALLY
609 Any line which starts with a I<!> character is treated as a command
610 sent to the local shell (C</bin/sh> or whatever L<system(3)> uses).
614 tgz-out /remote local/remote-data.tar.gz
616 will create a directory C<local> on the host, and then export
617 the contents of C</remote> on the mounted filesystem to
618 C<local/remote-data.tar.gz>. (See C<tgz-out>).
620 To change the local directory, use the C<lcd> command. C<!cd> will
621 have no effect, due to the way that subprocesses work in Unix.
625 Use C<command E<lt>spaceE<gt> | command> to pipe the output of the
626 first command (a guestfish command) to the second command (any host
627 command). For example:
629 cat /etc/passwd | awk -F: '$3 == 0 { print }'
631 (where C<cat> is the guestfish cat command, but C<awk> is the host awk
632 program). The above command would list all accounts in the guest
633 filesystem which have UID 0, ie. root accounts including backdoors.
636 hexdump /bin/ls | head
637 list-devices | tail -1
638 tgz-out / - | tar ztf -
640 The space before the pipe symbol is required, any space after the pipe
641 symbol is optional. Everything after the pipe symbol is just passed
642 straight to the host shell, so it can contain redirections, globs and
643 anything else that makes sense on the host side.
645 To use a literal argument which begins with a pipe symbol, you have
650 =head1 HOME DIRECTORIES
652 If a parameter starts with the character C<~> then the tilde may be
653 expanded as a home directory path (either C<~> for the current user's
654 home directory, or C<~user> for another user).
656 Note that home directory expansion happens for users known I<on the
657 host>, not in the guest filesystem.
659 To use a literal argument which begins with a tilde, you have to quote
664 =head1 ENCRYPTED DISKS
666 Libguestfs has some support for Linux guests encrypted according to
667 the Linux Unified Key Setup (LUKS) standard, which includes nearly all
668 whole disk encryption systems used by modern Linux guests. Currently
669 only LVM-on-LUKS is supported.
671 Identify encrypted block devices and partitions using L</vfs-type>:
673 ><fs> vfs-type /dev/sda2
676 Then open those devices using L</luks-open>. This creates a
677 device-mapper device called C</dev/mapper/luksdev>.
679 ><fs> luks-open /dev/sda2 luksdev
680 Enter key or passphrase ("key"): <enter the passphrase>
682 Finally you have to tell LVM to scan for volume groups on
683 the newly created mapper device:
688 The logical volume(s) can now be mounted in the usual way.
690 Before closing a LUKS device you must unmount any logical volumes on
691 it and deactivate the volume groups by calling C<vg-activate false VG>
692 on each one. Then you can close the mapper device:
694 vg-activate false /dev/VG
695 luks-close /dev/mapper/luksdev
699 If a path is prefixed with C<win:> then you can use Windows-style
700 paths (with some limitations). The following commands are equivalent:
702 file /WINDOWS/system32/config/system.LOG
704 file win:/windows/system32/config/system.log
706 file win:\windows\system32\config\system.log
708 file WIN:C:\Windows\SYSTEM32\conFIG\SYSTEM.LOG
710 This syntax implicitly calls C<case-sensitive-path> (q.v.) so it also
711 handles case insensitivity like Windows would. This only works in
712 argument positions that expect a path.
714 =head1 UPLOADING AND DOWNLOADING FILES
716 For commands such as C<upload>, C<download>, C<tar-in>, C<tar-out> and
717 others which upload from or download to a local file, you can use the
718 special filename C<-> to mean "from stdin" or "to stdout". For example:
722 reads stdin and creates from that a file C</foo> in the disk image,
725 tar-out /etc - | tar tf -
727 writes the tarball to stdout and then pipes that into the external
728 "tar" command (see L</PIPES>).
730 When using C<-> to read from stdin, the input is read up to the end of
731 stdin. You can also use a special "heredoc"-like syntax to read up to
732 some arbitrary end marker:
740 Any string of characters can be used instead of C<END>. The end
741 marker must appear on a line of its own, without any preceeding or
742 following characters (not even spaces).
744 Note that the C<-E<lt>E<lt>> syntax only applies to parameters used to
745 upload local files (so-called "FileIn" parameters in the generator).
747 =head1 EXIT ON ERROR BEHAVIOUR
749 By default, guestfish will ignore any errors when in interactive mode
750 (ie. taking commands from a human over a tty), and will exit on the
751 first error in non-interactive mode (scripts, commands given on the
754 If you prefix a command with a I<-> character, then that command will
755 not cause guestfish to exit, even if that (one) command returns an
758 =head1 REMOTE CONTROL GUESTFISH OVER A SOCKET
760 Guestfish can be remote-controlled over a socket. This is useful
761 particularly in shell scripts where you want to make several different
762 changes to a filesystem, but you don't want the overhead of starting
763 up a guestfish process each time.
765 Start a guestfish server process using:
767 eval "`guestfish --listen`"
769 and then send it commands by doing:
771 guestfish --remote cmd [...]
773 To cause the server to exit, send it the exit command:
775 guestfish --remote exit
777 Note that the server will normally exit if there is an error in a
778 command. You can change this in the usual way. See section
779 L</EXIT ON ERROR BEHAVIOUR>.
781 =head2 CONTROLLING MULTIPLE GUESTFISH PROCESSES
783 The C<eval> statement sets the environment variable C<$GUESTFISH_PID>,
784 which is how the I<--remote> option knows where to send the commands.
785 You can have several guestfish listener processes running using:
787 eval "`guestfish --listen`"
789 eval "`guestfish --listen`"
792 guestfish --remote=$pid1 cmd
793 guestfish --remote=$pid2 cmd
795 =head2 REMOTE CONTROL DETAILS
797 Remote control happens over a Unix domain socket called
798 C</tmp/.guestfish-$UID/socket-$PID>, where C<$UID> is the effective
799 user ID of the process, and C<$PID> is the process ID of the server.
801 Guestfish client and server versions must match exactly.
803 =head1 PREPARED DISK IMAGES
805 Use the I<-N type> or I<--new type> parameter to select one of a set
806 of preformatted disk images that guestfish can make for you to save
807 typing. This is particularly useful for testing purposes. This
808 option is used instead of the I<-a> option, and like I<-a> can appear
809 multiple times (and can be mixed with I<-a>).
811 The new disk is called C<test1.img> for the first I<-N>, C<test2.img>
812 for the second and so on. Existing files in the current directory are
815 The type briefly describes how the disk should be sized, partitioned,
816 how filesystem(s) should be created, and how content should be added.
817 Optionally the type can be followed by extra parameters, separated by
818 C<:> (colon) characters. For example, I<-N fs> creates a default
819 100MB, sparsely-allocated disk, containing a single partition, with
820 the partition formatted as ext2. I<-N fs:ext4:1G> is the same, but
821 for an ext4 filesystem on a 1GB disk instead.
823 To list the available types and any extra parameters they take, run:
825 guestfish -N help | less
827 Note that the prepared filesystem is not mounted. You would usually
828 have to use the C<mount /dev/sda1 /> command or add the
829 I<-m /dev/sda1> option.
831 If any I<-N> or I<--new> options are given, the guest is automatically
836 Create a 100MB disk with an ext4-formatted partition:
840 Create a 32MB disk with a VFAT-formatted partition, and mount it:
842 guestfish -N fs:vfat:32M -m /dev/sda1
844 Create a blank 200MB disk:
846 guestfish -N disk:200M
850 Some (not all) long-running commands send progress notification
851 messages as they are running. Guestfish turns these messages into
854 When a command that supports progress bars takes longer than two
855 seconds to run, and if progress bars are enabled, then you will see
856 one appearing below the command:
858 ><fs> copy-size /large-file /another-file 2048M
859 / 10% [#####-----------------------------------------] 00:30
861 The spinner on the left hand side moves round once for every progress
862 notification received from the backend. This is a (reasonably) golden
863 assurance that the command is "doing something" even if the progress
864 bar is not moving, because the command is able to send the progress
865 notifications. When the bar reaches 100% and the command finishes,
866 the spinner disappears.
868 Progress bars are enabled by default when guestfish is used
869 interactively. You can enable them even for non-interactive modes
870 using I<--progress-bars>, and you can disable them completely using
871 I<--no-progress-bars>.
873 =head1 GUESTFISH COMMANDS
875 The commands in this section are guestfish convenience commands, in
876 other words, they are not part of the L<guestfs(3)> API.
883 Without any parameter, this lists all commands. With a C<cmd>
884 parameter, this displays detailed help for a command.
888 This exits guestfish. You can also use C<^D> key.
898 guestfish returns 0 if the commands completed without error, or
899 1 if there was an error.
901 =head1 ENVIRONMENT VARIABLES
907 The C<edit> command uses C<$EDITOR> as the editor. If not
912 Used with the I<--remote> option to specify the remote guestfish
913 process to control. See section
914 L</REMOTE CONTROL GUESTFISH OVER A SOCKET>.
918 The L</hexedit> command uses C<$HEXEDITOR> as the external hex
919 editor. If not specified, the external L<hexedit(1)> program
924 If compiled with GNU readline support, various files in the
925 home directory can be used. See L</FILES>.
927 =item LIBGUESTFS_APPEND
929 Pass additional options to the guest kernel.
931 =item LIBGUESTFS_DEBUG
933 Set C<LIBGUESTFS_DEBUG=1> to enable verbose messages. This has the
934 same effect as using the B<-v> option.
936 =item LIBGUESTFS_MEMSIZE
938 Set the memory allocated to the qemu process, in megabytes. For
941 LIBGUESTFS_MEMSIZE=700
943 =item LIBGUESTFS_PATH
945 Set the path that guestfish uses to search for kernel and initrd.img.
946 See the discussion of paths in L<guestfs(3)>.
948 =item LIBGUESTFS_QEMU
950 Set the default qemu binary that libguestfs uses. If not set, then
951 the qemu which was found at compile time by the configure script is
954 =item LIBGUESTFS_TRACE
956 Set C<LIBGUESTFS_TRACE=1> to enable command traces.
960 The C<more> command uses C<$PAGER> as the pager. If not
961 set, it uses C<more>.
965 Location of temporary directory, defaults to C</tmp>.
967 If libguestfs was compiled to use the supermin appliance then the
968 real appliance is cached in this directory, shared between all
969 handles belonging to the same EUID. You can use C<$TMPDIR> to
970 configure another directory to use in case C</tmp> is not large
979 =item $HOME/.guestfish
981 If compiled with GNU readline support, then the command history
982 is saved in this file.
988 If compiled with GNU readline support, then these files can be used to
989 configure readline. For further information, please see
990 L<readline(3)/INITIALIZATION FILE>.
992 To write rules which only apply to guestfish, use:
998 Variables that you can set in inputrc that change the behaviour
999 of guestfish in useful ways include:
1003 =item completion-ignore-case (default: on)
1005 By default, guestfish will ignore case when tab-completing
1006 paths on the disk. Use:
1008 set completion-ignore-case off
1010 to make guestfish case sensitive.
1016 =item test2.img (etc)
1018 When using the C<-N> or C<--new> option, the prepared disk or
1019 filesystem will be created in the file C<test1.img> in the current
1020 directory. The second use of C<-N> will use C<test2.img> and so on.
1021 Any existing file with the same name will be overwritten.
