=head1 DESCRIPTION
Guestfish is a shell and command-line tool for examining and modifying
Add a block device or virtual machine image to the shell.
+=item B<-f file> | B<--file file>
+
+Read commands from C<file>. To write pure guestfish
+scripts, use:
+
+ #!/usr/bin/guestfish -f
+
+=item B<-i> | B<--inspector>
+
+Run virt-inspector on the named libvirt domain or list of disk
+images. If virt-inspector is available and if it can identify
+the domain or disk images, then partitions will be mounted
+correctly at start-up.
+
+Typical usage is either:
+
+ guestfish -i myguest
+
+(for an inactive libvirt domain called I<myguest>), or:
+
+ guestfish --ro -i myguest
+
+(for active domains, readonly), or specify the block device directly:
+
+ guestfish -i /dev/Guests/MyGuest
+
+You cannot use I<-a> or I<-m> in conjunction with this option, and
+options other than I<--ro> might not behave correctly.
+
+See also: L<virt-inspector(1)>.
+
=item B<-m dev[:mountpoint]> | B<--mount dev[:mountpoint]>
Mount the named partition or logical volume on the given mountpoint.
this causes extra "hidden" guestfs calls to be made, so this option is
here to allow this feature to be disabled.
+=item B<-V> | B<--version>
+
+Display the guestfish / libguestfs version number and exit.

vgcreate VG "/dev/sda1 /dev/sdb1"
+=head1 WILDCARDS AND GLOBBING
+
+Neither guestfish nor the underlying guestfs API performs
+wildcard expansion (globbing) by default. So for example the
+following will not do what you expect:
+
+ rm-rf /home/*
+
+Assuming you don't have a directory literally called C</home/*>
+then the above command will return an error.
+
+To perform wildcard expansion, use the C<glob> command.
+
+ glob rm-rf /home/*
+
+runs C<rm-rf> on each path that matches (ie. potentially running
+the command many times), equivalent to:
+
+ rm-rf /home/jim
+ rm-rf /home/joe
+ rm-rf /home/mary
+
+C<glob> only works on simple guest paths and not on device names.
+
+If you have several parameters, each containing a wildcard, then glob
+will perform a cartesian product.
+
=head1 COMMENTS
Any line which starts with a I<#> character is treated as a comment
the contents of C</remote> on the mounted filesystem to
C<local/remote-data.tar.gz>. (See C<tgz-out>).
+=head1 PIPES
+
+Use C<command E<lt>spaceE<gt> | command> to pipe the output of the
+first command (a guestfish command) to the second command (any host
+command). For example:
+
+ cat /etc/passwd | awk -F: '$3 == 0 { print }'
+
+(where C<cat> is the guestfish cat command, but C<awk> is the host awk
+program). The above command would list all accounts in the guest
+filesystem which have UID 0, ie. root accounts including backdoors.
+Other examples:
+
+ hexdump /bin/ls | head
+ list-devices | tail -1
+
+The space before the pipe symbol is required, any space after the pipe
+symbol is optional. Everything after the pipe symbol is just passed
+straight to the host shell, so it can contain redirections, globs and
+anything else that makes sense on the host side.
+
+To use a literal argument which begins with a pipe symbol, you have
+to quote it, eg:
+
+ echo "|"
+
=head1 EXIT ON ERROR BEHAVIOUR
By default, guestfish will ignore any errors when in interactive mode
not cause guestfish to exit, even if that (one) command returns an
error.

+Expand wildcards in any paths in the args list, and run C<command>

Note that C<!cd> won't do what you might expect.

+
+ more filename
+
+ less filename
+
+This is used to view a file.
+
+The default viewer is C<$PAGER>. However if you use the alternate

+=head2 quit | exit
