=head2 cat
cat path
Return the contents of the file named C<path>.
Note that this function cannot correctly handle binary files
(specifically, files containing C<\0> character which is treated
as end of string). For those you need to use the C<guestfs_read_file>
function which has a more complex interface.
=head2 list-devices
list-devices
List all the block devices.
The full block device names are returned, eg. C</dev/sda>
=head2 list-partitions
list-partitions
List all the partitions detected on all block devices.
The full partition device names are returned, eg. C</dev/sda1>
This does not return logical volumes. For that you will need to
call C<guestfs_lvs>.
=head2 ll
ll directory
List the files in C<directory> (relative to the root directory,
there is no cwd) in the format of 'ls -la'.
This command is mostly useful for interactive sessions. It
is I<not> intended that you try to parse the output string.
=head2 ls
ls directory
List the files in C<directory> (relative to the root directory,
there is no cwd). The '.' and '..' entries are not returned, but
hidden files are shown.
This command is mostly useful for interactive sessions. Programs
should probably use C<guestfs_readdir> instead.
=head2 lvs
lvs
List all the logical volumes detected. This is the equivalent
of the L<lvs(8)> command.
This returns a list of the logical volume device names
(eg. C</dev/VolGroup00/LogVol00>).
See also C<guestfs_lvs_full>.
=head2 lvs-full
lvs-full
List all the logical volumes detected. This is the equivalent
of the L<lvs(8)> command. The "full" version includes all fields.
=head2 mount
mount device mountpoint
Mount a guest disk at a position in the filesystem. Block devices
are named C</dev/sda>, C</dev/sdb> and so on, as they were added to
the guest. If those block devices contain partitions, they will have
the usual names (eg. C</dev/sda1>). Also LVM C</dev/VG/LV>-style
names can be used.
The rules are the same as for L<mount(2)>: A filesystem must
first be mounted on C</> before others can be mounted. Other
filesystems can only be mounted on directories which already
exist.
The mounted filesystem is writable, if we have sufficient permissions
on the underlying device.
The filesystem options C<sync> and C<noatime> are set with this
call, in order to improve reliability.
=head2 pvs
pvs
List all the physical volumes detected. This is the equivalent
of the L<pvs(8)> command.
This returns a list of just the device names that contain
PVs (eg. C</dev/sda2>).
See also C<guestfs_pvs_full>.
=head2 pvs-full
pvs-full
List all the physical volumes detected. This is the equivalent
of the L<pvs(8)> command. The "full" version includes all fields.
=head2 sync
sync
This syncs the disk, so that any writes are flushed through to the
underlying disk image.
You should always call this if you have modified a disk image, before
calling C<guestfs_close>.
=head2 touch
touch path
Touch acts like the L<touch(1)> command. It can be used to
update the timestamps on a file, or, if the file does not exist,
to create a new zero-length file.
=head2 vgs
vgs
List all the volumes groups detected. This is the equivalent
of the L<vgs(8)> command.
This returns a list of just the volume group names that were
detected (eg. C<VolGroup00>).
See also C<guestfs_vgs_full>.
=head2 vgs-full
vgs-full
List all the volumes groups detected. This is the equivalent
of the L<vgs(8)> command. The "full" version includes all fields.
