=item B<--append-line> FILE:LINE

Append a single line of text to the C<FILE>.  If the file does not already end with a newline, then one is added before the appended line.  Also a newline is added to the end of the C<LINE> string automatically.

For example (assuming ordinary shell quoting) this command:

 --append-line '/etc/hosts:10.0.0.1 foo'

will add either C<10.0.0.1 foo⏎> or C<⏎10.0.0.1 foo⏎> to the file, the latter only if the existing file does not already end with a newline.

C<⏎> represents a newline character, which is guessed by looking at the existing content of the file, so this command does the right thing for files using Unix or Windows line endings.  It also works for empty or non-existent files.

To insert several lines, use the same option several times:

 --append-line '/etc/hosts:10.0.0.1 foo'
 --append-line '/etc/hosts:10.0.0.2 bar'

To insert a blank line before the appended line, do:

 --append-line '/etc/hosts:'
 --append-line '/etc/hosts:10.0.0.1 foo'

=item B<--chmod> PERMISSIONS:FILE

Change the permissions of C<FILE> to C<PERMISSIONS>.

I<Note>: C<PERMISSIONS> by default would be decimal, unless you prefix it with C<0> to get octal, ie. use C<0700> not C<700>.

=item B<--chown> UID:GID:PATH

Change the owner user and group ID of a file or directory in the guest. Note:

=over 4

=item *

Only numeric UIDs and GIDs will work, and these may not be the same inside the guest as on the host.

=item *

This will not work with Windows guests.

=back

例:

 virt-customize --chown '0:0:/var/log/audit.log'

See also: I<--upload>.

=item B<--commands-from-file> FILENAME

Read the customize commands from a file, one (and its arguments)  each line.

Each line contains a single customization command and its arguments, for example:

 delete /some/file
 install some-package
 password some-user:password:its-new-password

Empty lines are ignored, and lines starting with C<#> are comments and are ignored as well.  Furthermore, arguments can be spread across multiple lines, by adding a C<\> (continuation character) at the of a line, for example

 edit /some/file:\
   s/^OPT=.*/OPT=ok/

The commands are handled in the same order as they are in the file, as if they were specified as I<--delete /some/file> on the command line.

=item B<--copy> SOURCE:DEST

Copy files or directories recursively inside the guest.

Wildcards cannot be used.

=item B<--copy-in> LOCALPATH:REMOTEDIR

Copy local files or directories recursively into the disk image, placing them in the directory C<REMOTEDIR> (which must exist).

Wildcards cannot be used.

=item B<--delete> PATH

Delete a file from the guest.  Or delete a directory (and all its contents, recursively).

You can use shell glob characters in the specified path.  Be careful to escape glob characters from the host shell, if that is required.  For example:

 virt-customize --delete '/var/log/*.log'.

See also: I<--upload>, I<--scrub>.

=item B<--edit> FILE:EXPR

Edit C<FILE> using the Perl expression C<EXPR>.

表現がシェルにより変更されるのを防ぐために、適切に引用符でくくるよう注意してください。

このオプションは Perl 5 がインストールされているときのみ利用可能であることに注意してください。

See L<virt-edit(1)/NON-INTERACTIVE EDITING>.

=item B<--firstboot> SCRIPT

Install C<SCRIPT> inside the guest, so that when the guest first boots up, the script runs (as root, late in the boot process).

The script is automatically chmod +x after installation in the guest.

The alternative version I<--firstboot-command> is the same, but it conveniently wraps the command up in a single line script for you.

You can have multiple I<--firstboot> options.  They run in the same order that they appear on the command line.

See also: L<virt-customize(1)/FIRSTBOOT>, I<--run>.

=item B<--firstboot-command> 'CMD+ARGS'

Run command (and arguments) inside the guest when the guest first boots up (as root, late in the boot process).

You can have multiple I<--firstboot> options.  They run in the same order that they appear on the command line.

See also: L<virt-customize(1)/FIRSTBOOT>, I<--run>.

=item B<--firstboot-install> PKG,PKG..

Install the named packages (a comma-separated list).  These are installed when the guest first boots using the guest’s package manager (eg. apt, yum, etc.) and the guest’s network connection.

For an overview on the different ways to install packages, see L<virt-builder(1)/INSTALLING PACKAGES>.

=item B<--hostname> HOSTNAME

Set the hostname of the guest to C<HOSTNAME>.  You can use a dotted hostname.domainname (FQDN) if you want.

=item B<--install> PKG,PKG..

Install the named packages (a comma-separated list).  These are installed during the image build using the guest’s package manager (eg. apt, yum, etc.) and the host’s network connection.

For an overview on the different ways to install packages, see L<virt-builder(1)/INSTALLING PACKAGES>.

See also I<--update>, I<--uninstall>.

=item B<--link> TARGET:LINK[:LINK..]

Create symbolic link(s) in the guest, starting at C<LINK> and pointing at C<TARGET>.

=item B<--mkdir> DIR

Create a directory in the guest.

This uses S<C<mkdir -p>> so any intermediate directories are created, and it also works if the directory already exists.

=item B<--move> SOURCE:DEST

Move files or directories inside the guest.

Wildcards cannot be used.

=item B<--no-logfile>

Scrub C<builder.log> (log file from build commands) from the image after building is complete.  If you don't want to reveal precisely how the image was built, use this option.

See also: L</LOG FILE>.

=item B<--no-selinux-relabel>

Do not attempt to correct the SELinux labels of files in the guest.

In such guests that support SELinux, customization automatically relabels files so that they have the correct SELinux label.  (The relabeling is performed immediately, but if the operation fails, customization will instead touch F</.autorelabel> on the image to schedule a relabel operation for the next time the image boots.)  This option disables the automatic relabeling.

The option is a no-op for guests that do not support SELinux.

=item B<--password> USER:SELECTOR

Set the password for C<USER>.  (Note this option does I<not> create the user account).

See L<virt-builder(1)/USERS AND PASSWORDS> for the format of the C<SELECTOR> field, and also how to set up user accounts.

=item B<--password-crypto> md5|sha256|sha512

When the virt tools change or set a password in the guest, this option sets the password encryption of that password to C<md5>, C<sha256> or C<sha512>.

C<sha256> and C<sha512> require glibc E<ge> 2.7 (check crypt(3) inside the guest).

C<md5> will work with relatively old Linux guests (eg. RHEL 3), but is not secure against modern attacks.

The default is C<sha512> unless libguestfs detects an old guest that didn't have support for SHA-512, in which case it will use C<md5>.  You can override libguestfs by specifying this option.

Note this does not change the default password encryption used by the guest when you create new user accounts inside the guest.  If you want to do that, then you should use the I<--edit> option to modify C</etc/sysconfig/authconfig> (Fedora, RHEL) or C</etc/pam.d/common-password> (Debian, Ubuntu).

=item B<--root-password> SELECTOR

Set the root password.

See L<virt-builder(1)/USERS AND PASSWORDS> for the format of the C<SELECTOR> field, and also how to set up user accounts.

Note: In virt-builder, if you I<don't> set I<--root-password> then the guest is given a I<random> root password.

=item B<--run> SCRIPT

Run the shell script (or any program) called C<SCRIPT> on the disk image. The script runs virtualized inside a small appliance, chrooted into the guest filesystem.

The script is automatically chmod +x.

If libguestfs supports it then a limited network connection is available but it only allows outgoing network connections.  You can also attach data disks (eg. ISO files) as another way to provide data (eg. software packages) to the script without needing a network connection (I<--attach>).  You can also upload data files (I<--upload>).

You can have multiple I<--run> options.  They run in the same order that they appear on the command line.

See also: I<--firstboot>, I<--attach>, I<--upload>.

=item B<--run-command> 'CMD+ARGS'

Run the command and arguments on the disk image.  The command runs virtualized inside a small appliance, chrooted into the guest filesystem.

If libguestfs supports it then a limited network connection is available but it only allows outgoing network connections.  You can also attach data disks (eg. ISO files) as another way to provide data (eg. software packages) to the script without needing a network connection (I<--attach>).  You can also upload data files (I<--upload>).

You can have multiple I<--run-command> options.  They run in the same order that they appear on the command line.

See also: I<--firstboot>, I<--attach>, I<--upload>.

=item B<--scrub> FILE

Scrub a file from the guest.  This is like I<--delete> except that:

=over 4

=item *

It scrubs the data so a guest could not recover it.

=item *

It cannot delete directories, only regular files.

=back

=item B<--selinux-relabel>

This is a compatibility option that does nothing.

=item B<--ssh-inject> USER[:SELECTOR]

Inject an ssh key so the given C<USER> will be able to log in over ssh without supplying a password.  The C<USER> must exist already in the guest.

See L<virt-builder(1)/SSH KEYS> for the format of the C<SELECTOR> field.

You can have multiple I<--ssh-inject> options, for different users and also for more keys for each user.

=item B<--tar-in> TARFILE:REMOTEDIR

Copy local files or directories from a local tar file called C<TARFILE> into the disk image, placing them in the directory C<REMOTEDIR> (which must exist).  Note that the tar file must be uncompressed (F<.tar.gz> files will not work here)

=item B<--timezone> TIMEZONE

Set the default timezone of the guest to C<TIMEZONE>.  Use a location string like C<Europe/London>

=item B<--touch> FILE

This command performs a L<touch(1)>-like operation on C<FILE>.

=item B<--truncate> FILE

This command truncates C<FILE> to a zero-length file. The file must exist already.

=item B<--truncate-recursive> PATH

This command recursively truncates all files under C<PATH> to zero-length.

=item B<--uninstall> PKG,PKG..

Uninstall the named packages (a comma-separated list).  These are removed during the image build using the guest’s package manager (eg. apt, yum, etc.).  Dependent packages may also need to be uninstalled to satisfy the request.

See also I<--install>, I<--update>.

=item B<--update>

Do the equivalent of C<yum update>, C<apt-get upgrade>, or whatever command is required to update the packages already installed in the template to their latest versions.

See also I<--install>, I<--uninstall>.

=item B<--upload> FILE:DEST

Upload local file C<FILE> to destination C<DEST> in the disk image.  File owner and permissions from the original are preserved, so you should set them to what you want them to be in the disk image.

C<DEST> could be the final filename.  This can be used to rename the file on upload.

If C<DEST> is a directory name (which must already exist in the guest)  then the file is uploaded into that directory, and it keeps the same name as on the local filesystem.

See also: I<--mkdir>, I<--delete>, I<--scrub>.

=item B<--write> FILE:CONTENT

Write C<CONTENT> to C<FILE>.
