=encoding utf8 =head1 NAME virt-ls - List files in a virtual machine =head1 SYNOPSIS virt-ls [--options] -d domname directory [directory ...] virt-ls [--options] -a disk.img [-a disk.img ...] directory [directory ...] Old style: virt-ls [--options] domname directory virt-ls [--options] disk.img [disk.img ...] directory =head1 DESCRIPTION C is a command line tool to list the names of files in a directory inside a virtual machine or disk image. Multiple directory names can be given, in which case the output from each is concatenated. C is just a simple wrapper around L functionality. For more complex cases you should look at the L tool. To list directories from a libvirt guest use the I<-d> option to specify the name of the guest. For a disk image, use the I<-a> option. C can be used in one of three modes: simple, long and recursive. A simple listing is like the ordinary L command: $ virt-ls -d myguest / bin boot [etc.] With the I<-l> (I<--long>) option, C shows more detail: $ virt-ls -l -d myguest / total 204 dr-xr-xr-x. 2 root root 4096 2009-08-25 19:06 bin dr-xr-xr-x. 5 root root 3072 2009-08-25 19:06 boot [etc.] With the I<-R> (I<--recursive>) option, C lists the names of files and directories recursively: $ virt-ls -R -d myguest /tmp foo foo/bar [etc.] You I combine these options. To do more complicated things, use L. =head1 OPTIONS =over 4 =item B<--help> Display brief help. =item B<-a> file =item B<--add> file Add I which should be a disk image from a virtual machine. If the virtual machine has multiple block devices, you must supply all of them with separate I<-a> options. The format of the disk image is auto-detected. To override this and force a particular format use the I<--format=..> option. =item B<-c> URI =item B<--connect> URI If using libvirt, connect to the given I. If omitted, then we connect to the default libvirt hypervisor. If you specify guest block devices directly (I<-a>), then libvirt is not used at all. =item B<-d> guest =item B<--domain> guest Add all the disks from the named libvirt guest. =item B<--echo-keys> When prompting for keys and passphrases, virt-ls normally turns echoing off so you cannot see what you are typing. If you are not worried about Tempest attacks and there is no one else in the room you can specify this flag to see what you are typing. =item B<--format=raw|qcow2|..> =item B<--format> The default for the I<-a> option is to auto-detect the format of the disk image. Using this forces the disk format for I<-a> options which follow on the command line. Using I<--format> with no argument switches back to auto-detection for subsequent I<-a> options. For example: virt-ls --format=raw -a disk.img /dir forces raw format (no auto-detection) for C. virt-ls --format=raw -a disk.img --format -a another.img /dir forces raw format (no auto-detection) for C and reverts to auto-detection for C. If you have untrusted raw-format guest disk images, you should use this option to specify the disk format. This avoids a possible security problem with malicious guests (CVE-2010-3851). =item B<--keys-from-stdin> Read key or passphrase parameters from stdin. The default is to try to read passphrases from the user by opening C. =item B<-l> | B<--long> =item B<-R> | B<--recursive> Select the mode. With neither of these options, C produces a simple, flat list of the files in the named directory. C produces a "long listing", which shows more detail (just like the plain C command). C produces a recursive list of files starting at the named directory. See the documentation for L for precise details. You cannot combine these options. =item B<-v> =item B<--verbose> Enable verbose messages for debugging. =item B<-V> =item B<--version> Display version number and exit. =item B<-x> Enable tracing of libguestfs API calls. =back =head1 OLD-STYLE COMMAND LINE ARGUMENTS Previous versions of virt-ls allowed you to write either: virt-ls disk.img [disk.img ...] /dir or virt-ls guestname /dir whereas in this version you should use I<-a> or I<-d> respectively to avoid the confusing case where a disk image might have the same name as a guest. For compatibility the old style is still supported. =head1 SHELL QUOTING Libvirt guest names can contain arbitrary characters, some of which have meaning to the shell such as C<#> and space. You may need to quote or escape these characters on the command line. See the shell manual page L for details. =head1 SEE ALSO L, L, L, L, L, L, L, L. =head1 AUTHOR Richard W.M.
