5 guestfish - the libguestfs Filesystem Interactive SHell
9 guestfish [--options] [commands]
15 guestfish -a disk.img -m dev[:mountpoint]
17 guestfish -d libvirt-domain
19 guestfish -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 --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 -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 -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
325 Enable SELinux support for the guest. See L<guestfs(3)/SELINUX>.
327 =item B<-v> | B<--verbose>
329 Enable very verbose messages. This is particularly useful if you find
332 =item B<-V> | B<--version>
334 Display the guestfish / libguestfs version number and exit.
338 Echo each command before executing it.
342 =head1 COMMANDS ON COMMAND LINE
344 Any additional (non-option) arguments are treated as commands to
347 Commands to execute should be separated by a colon (C<:>), where the
348 colon is a separate parameter. Thus:
350 guestfish cmd [args...] : cmd [args...] : cmd [args...] ...
352 If there are no additional arguments, then we enter a shell, either an
353 interactive shell with a prompt (if the input is a terminal) or a
354 non-interactive shell.
356 In either command line mode or non-interactive shell, the first
357 command that gives an error causes the whole shell to exit. In
358 interactive mode (with a prompt) if a command fails, you can continue
361 =head1 USING launch (OR run)
363 As with L<guestfs(3)>, you must first configure your guest by adding
364 disks, then launch it, then mount any disks you need, and finally
365 issue actions/commands. So the general order of the day is:
387 C<run> is a synonym for C<launch>. You must C<launch> (or C<run>)
388 your guest before mounting or performing any other commands.
390 The only exception is that if any of the I<-i>, I<-m>, I<--mount>,
391 I<-N> or I<--new> options were given then C<run> is done
392 automatically, simply because guestfish can't perform the action you
393 asked for without doing this.
397 You can quote ordinary parameters using either single or double
400 add "file with a space.img"
406 A few commands require a list of strings to be passed. For these, use
407 a whitespace-separated list, enclosed in quotes. Strings containing whitespace
408 to be passed through must be enclosed in single quotes. A literal single quote
409 must be escaped with a backslash.
411 vgcreate VG "/dev/sda1 /dev/sdb1"
412 command "/bin/echo 'foo bar'"
413 command "/bin/echo \'foo\'"
415 =head1 OPTIONAL ARGUMENTS
417 Some commands take optional arguments. These arguments appear in this
418 documentation as C<[argname:..]>. You can use them as in these
421 add-drive-opts filename
423 add-drive-opts filename readonly:true
425 add-drive-opts filename format:qcow2 readonly:false
427 Each optional argument can appear at most once. All optional
428 arguments must appear after the required ones.
432 This section applies to all commands which can take integers
437 When the command takes a parameter measured in bytes, you can use one
438 of the following suffixes to specify kilobytes, megabytes and larger
443 =item B<k> or B<K> or B<KiB>
445 The size in kilobytes (multiplied by 1024).
449 The size in SI 1000 byte units.
453 The size in megabytes (multiplied by 1048576).
457 The size in SI 1000000 byte units.
461 The size in gigabytes (multiplied by 2**30).
465 The size in SI 10**9 byte units.
469 The size in terabytes (multiplied by 2**40).
473 The size in SI 10**12 byte units.
477 The size in petabytes (multiplied by 2**50).
481 The size in SI 10**15 byte units.
485 The size in exabytes (multiplied by 2**60).
489 The size in SI 10**18 byte units.
493 The size in zettabytes (multiplied by 2**70).
497 The size in SI 10**21 byte units.
501 The size in yottabytes (multiplied by 2**80).
505 The size in SI 10**24 byte units.
511 truncate-size /file 1G
513 would truncate the file to 1 gigabyte.
515 Be careful because a few commands take sizes in kilobytes or megabytes
516 (eg. the parameter to L</memsize> is specified in megabytes already).
517 Adding a suffix will probably not do what you expect.
519 =head2 OCTAL AND HEXADECIMAL NUMBERS
521 For specifying the radix (base) use the C convention: C<0> to prefix
522 an octal number or C<0x> to prefix a hexadecimal number. For example:
524 1234 decimal number 1234
525 02322 octal number, equivalent to decimal 1234
526 0x4d2 hexadecimal number, equivalent to decimal 1234
528 When using the C<chmod> command, you almost always want to specify an
529 octal number for the mode, and you must prefix it with C<0> (unlike
530 the Unix L<chmod(1)> program):
532 chmod 0777 /public # OK
533 chmod 777 /public # WRONG! This is mode 777 decimal = 01411 octal.
535 Commands that return numbers usually print them in decimal, but
536 some commands print numbers in other radices (eg. C<umask> prints
537 the mode in octal, preceeded by C<0>).
539 =head1 WILDCARDS AND GLOBBING
541 Neither guestfish nor the underlying guestfs API performs
542 wildcard expansion (globbing) by default. So for example the
543 following will not do what you expect:
547 Assuming you don't have a directory called literally C</home/*>
548 then the above command will return an error.
550 To perform wildcard expansion, use the C<glob> command.
554 runs C<rm-rf> on each path that matches (ie. potentially running
555 the command many times), equivalent to:
561 C<glob> only works on simple guest paths and not on device names.
563 If you have several parameters, each containing a wildcard, then glob
564 will perform a Cartesian product.
568 Any line which starts with a I<#> character is treated as a comment
569 and ignored. The I<#> can optionally be preceeded by whitespace,
570 but B<not> by a command. For example:
576 Blank lines are also ignored.
578 =head1 RUNNING COMMANDS LOCALLY
580 Any line which starts with a I<!> character is treated as a command
581 sent to the local shell (C</bin/sh> or whatever L<system(3)> uses).
585 tgz-out /remote local/remote-data.tar.gz
587 will create a directory C<local> on the host, and then export
588 the contents of C</remote> on the mounted filesystem to
589 C<local/remote-data.tar.gz>. (See C<tgz-out>).
591 To change the local directory, use the C<lcd> command. C<!cd> will
592 have no effect, due to the way that subprocesses work in Unix.
596 Use C<command E<lt>spaceE<gt> | command> to pipe the output of the
597 first command (a guestfish command) to the second command (any host
598 command). For example:
600 cat /etc/passwd | awk -F: '$3 == 0 { print }'
602 (where C<cat> is the guestfish cat command, but C<awk> is the host awk
603 program). The above command would list all accounts in the guest
604 filesystem which have UID 0, ie. root accounts including backdoors.
607 hexdump /bin/ls | head
608 list-devices | tail -1
609 tgz-out / - | tar ztf -
611 The space before the pipe symbol is required, any space after the pipe
612 symbol is optional. Everything after the pipe symbol is just passed
613 straight to the host shell, so it can contain redirections, globs and
614 anything else that makes sense on the host side.
616 To use a literal argument which begins with a pipe symbol, you have
621 =head1 HOME DIRECTORIES
623 If a parameter starts with the character C<~> then the tilde may be
624 expanded as a home directory path (either C<~> for the current user's
625 home directory, or C<~user> for another user).
627 Note that home directory expansion happens for users known I<on the
628 host>, not in the guest filesystem.
630 To use a literal argument which begins with a tilde, you have to quote
635 =head1 ENCRYPTED DISKS
637 Libguestfs has some support for Linux guests encrypted according to
638 the Linux Unified Key Setup (LUKS) standard, which includes nearly all
639 whole disk encryption systems used by modern Linux guests. Currently
640 only LVM-on-LUKS is supported.
642 Identify encrypted block devices and partitions using L</vfs-type>:
644 ><fs> vfs-type /dev/sda2
647 Then open those devices using L</luks-open>. This creates a
648 device-mapper device called C</dev/mapper/luksdev>.
650 ><fs> luks-open /dev/sda2 luksdev
651 Enter key or passphrase ("key"): <enter the passphrase>
653 Finally you have to tell LVM to scan for volume groups on
654 the newly created mapper device:
659 The logical volume(s) can now be mounted in the usual way.
661 Before closing a LUKS device you must unmount any logical volumes on
662 it and deactivate the volume groups by calling C<vg-activate false VG>
663 on each one. Then you can close the mapper device:
665 vg-activate false /dev/VG
666 luks-close /dev/mapper/luksdev
670 If a path is prefixed with C<win:> then you can use Windows-style
671 paths (with some limitations). The following commands are equivalent:
673 file /WINDOWS/system32/config/system.LOG
675 file win:/windows/system32/config/system.log
677 file win:\windows\system32\config\system.log
679 file WIN:C:\Windows\SYSTEM32\conFIG\SYSTEM.LOG
681 This syntax implicitly calls C<case-sensitive-path> (q.v.) so it also
682 handles case insensitivity like Windows would. This only works in
683 argument positions that expect a path.
685 =head1 UPLOADING AND DOWNLOADING FILES
687 For commands such as C<upload>, C<download>, C<tar-in>, C<tar-out> and
688 others which upload from or download to a local file, you can use the
689 special filename C<-> to mean "from stdin" or "to stdout". For example:
693 reads stdin and creates from that a file C</foo> in the disk image,
696 tar-out /etc - | tar tf -
698 writes the tarball to stdout and then pipes that into the external
699 "tar" command (see L</PIPES>).
701 When using C<-> to read from stdin, the input is read up to the end of
702 stdin. You can also use a special "heredoc"-like syntax to read up to
703 some arbitrary end marker:
711 Any string of characters can be used instead of C<END>. The end
712 marker must appear on a line of its own, without any preceeding or
713 following characters (not even spaces).
715 Note that the C<-E<lt>E<lt>> syntax only applies to parameters used to
716 upload local files (so-called "FileIn" parameters in the generator).
718 =head1 EXIT ON ERROR BEHAVIOUR
720 By default, guestfish will ignore any errors when in interactive mode
721 (ie. taking commands from a human over a tty), and will exit on the
722 first error in non-interactive mode (scripts, commands given on the
725 If you prefix a command with a I<-> character, then that command will
726 not cause guestfish to exit, even if that (one) command returns an
729 =head1 REMOTE CONTROL GUESTFISH OVER A SOCKET
731 Guestfish can be remote-controlled over a socket. This is useful
732 particularly in shell scripts where you want to make several different
733 changes to a filesystem, but you don't want the overhead of starting
734 up a guestfish process each time.
736 Start a guestfish server process using:
738 eval "`guestfish --listen`"
740 and then send it commands by doing:
742 guestfish --remote cmd [...]
744 To cause the server to exit, send it the exit command:
746 guestfish --remote exit
748 Note that the server will normally exit if there is an error in a
749 command. You can change this in the usual way. See section
750 L</EXIT ON ERROR BEHAVIOUR>.
752 =head2 CONTROLLING MULTIPLE GUESTFISH PROCESSES
754 The C<eval> statement sets the environment variable C<$GUESTFISH_PID>,
755 which is how the I<--remote> option knows where to send the commands.
756 You can have several guestfish listener processes running using:
758 eval "`guestfish --listen`"
760 eval "`guestfish --listen`"
763 guestfish --remote=$pid1 cmd
764 guestfish --remote=$pid2 cmd
766 =head2 REMOTE CONTROL AND CSH
768 When using csh-like shells (csh, tcsh etc) you have to add the
771 eval "`guestfish --listen --csh`"
773 =head2 REMOTE CONTROL DETAILS
775 Remote control happens over a Unix domain socket called
776 C</tmp/.guestfish-$UID/socket-$PID>, where C<$UID> is the effective
777 user ID of the process, and C<$PID> is the process ID of the server.
779 Guestfish client and server versions must match exactly.
781 =head1 PREPARED DISK IMAGES
783 Use the I<-N type> or I<--new type> parameter to select one of a set
784 of preformatted disk images that guestfish can make for you to save
785 typing. This is particularly useful for testing purposes. This
786 option is used instead of the I<-a> option, and like I<-a> can appear
787 multiple times (and can be mixed with I<-a>).
789 The new disk is called C<test1.img> for the first I<-N>, C<test2.img>
790 for the second and so on. Existing files in the current directory are
793 The type briefly describes how the disk should be sized, partitioned,
794 how filesystem(s) should be created, and how content should be added.
795 Optionally the type can be followed by extra parameters, separated by
796 C<:> (colon) characters. For example, I<-N fs> creates a default
797 100MB, sparsely-allocated disk, containing a single partition, with
798 the partition formatted as ext2. I<-N fs:ext4:1G> is the same, but
799 for an ext4 filesystem on a 1GB disk instead.
801 To list the available types and any extra parameters they take, run:
803 guestfish -N help | less
805 Note that the prepared filesystem is not mounted. You would usually
806 have to use the C<mount /dev/sda1 /> command or add the
807 I<-m /dev/sda1> option.
809 If any I<-N> or I<--new> options are given, the guest is automatically
814 Create a 100MB disk with an ext4-formatted partition:
818 Create a 32MB disk with a VFAT-formatted partition, and mount it:
820 guestfish -N fs:vfat:32M -m /dev/sda1
822 Create a blank 200MB disk:
824 guestfish -N disk:200M
828 Some (not all) long-running commands send progress notification
829 messages as they are running. Guestfish turns these messages into
832 When a command that supports progress bars takes longer than two
833 seconds to run, and if progress bars are enabled, then you will see
834 one appearing below the command:
836 ><fs> copy-size /large-file /another-file 2048M
837 / 10% [#####-----------------------------------------] 00:30
839 The spinner on the left hand side moves round once for every progress
840 notification received from the backend. This is a (reasonably) golden
841 assurance that the command is "doing something" even if the progress
842 bar is not moving, because the command is able to send the progress
843 notifications. When the bar reaches 100% and the command finishes,
844 the spinner disappears.
846 Progress bars are enabled by default when guestfish is used
847 interactively. You can enable them even for non-interactive modes
848 using I<--progress-bars>, and you can disable them completely using
849 I<--no-progress-bars>.
851 =head1 GUESTFISH COMMANDS
853 The commands in this section are guestfish convenience commands, in
854 other words, they are not part of the L<guestfs(3)> API.
861 Without any parameter, this provides general help.
863 With a C<cmd> parameter, this displays detailed help for that command.
867 This exits guestfish. You can also use C<^D> key.
877 guestfish returns 0 if the commands completed without error, or
878 1 if there was an error.
880 =head1 ENVIRONMENT VARIABLES
886 The C<edit> command uses C<$EDITOR> as the editor. If not
891 Used with the I<--remote> option to specify the remote guestfish
892 process to control. See section
893 L</REMOTE CONTROL GUESTFISH OVER A SOCKET>.
897 The L</hexedit> command uses C<$HEXEDITOR> as the external hex
898 editor. If not specified, the external L<hexedit(1)> program
903 If compiled with GNU readline support, various files in the
904 home directory can be used. See L</FILES>.
906 =item LIBGUESTFS_APPEND
908 Pass additional options to the guest kernel.
910 =item LIBGUESTFS_DEBUG
912 Set C<LIBGUESTFS_DEBUG=1> to enable verbose messages. This has the
913 same effect as using the B<-v> option.
915 =item LIBGUESTFS_MEMSIZE
917 Set the memory allocated to the qemu process, in megabytes. For
920 LIBGUESTFS_MEMSIZE=700
922 =item LIBGUESTFS_PATH
924 Set the path that guestfish uses to search for kernel and initrd.img.
925 See the discussion of paths in L<guestfs(3)>.
927 =item LIBGUESTFS_QEMU
929 Set the default qemu binary that libguestfs uses. If not set, then
930 the qemu which was found at compile time by the configure script is
933 =item LIBGUESTFS_TRACE
935 Set C<LIBGUESTFS_TRACE=1> to enable command traces.
939 The C<more> command uses C<$PAGER> as the pager. If not
940 set, it uses C<more>.
944 Location of temporary directory, defaults to C</tmp>.
946 If libguestfs was compiled to use the supermin appliance then the
947 real appliance is cached in this directory, shared between all
948 handles belonging to the same EUID. You can use C<$TMPDIR> to
949 configure another directory to use in case C</tmp> is not large
958 =item $HOME/.guestfish
960 If compiled with GNU readline support, then the command history
961 is saved in this file.
967 If compiled with GNU readline support, then these files can be used to
968 configure readline. For further information, please see
969 L<readline(3)/INITIALIZATION FILE>.
971 To write rules which only apply to guestfish, use:
977 Variables that you can set in inputrc that change the behaviour
978 of guestfish in useful ways include:
982 =item completion-ignore-case (default: on)
984 By default, guestfish will ignore case when tab-completing
985 paths on the disk. Use:
987 set completion-ignore-case off
989 to make guestfish case sensitive.
995 =item test2.img (etc)
997 When using the C<-N> or C<--new> option, the prepared disk or
998 filesystem will be created in the file C<test1.img> in the current
999 directory. The second use of C<-N> will use C<test2.img> and so on.
1000 Any existing file with the same name will be overwritten.
