|
|---|
| 24 | =item B<--debug>
|
|---|
| 25 |
|
|---|
| 26 | Enter debug mode. This will print what would be done. No commands are executed,
|
|---|
| 27 | so this is safe to use when testing.
|
|---|
| 28 |
|
|---|
| 29 | =item B<--help>
|
|---|
| 30 |
|
|---|
| 31 | Print a brief help message and exits.
|
|---|
| 32 |
|
|---|
| 33 | =item B<--man>
|
|---|
| 34 |
|
|---|
| 35 | Prints the manual page and exits.
|
|---|
| 36 |
|
|---|
| 37 | =item B<--machine> I<machine name>
|
|---|
| 38 |
|
|---|
| 39 | Specify the machine to consider when dealing with the CasparBuster structure.
|
|---|
| 40 | The files will be pushed to this machine, and a subdirectory named after the machine
|
|---|
| 41 | will be used under the basedir to look at the directory structure to deploy
|
|---|
| 42 |
|
|---|
| 43 | =item B<--source> I<path>
|
|---|
| 44 |
|
|---|
| 45 | Specify the path of the source file or directory to deploy with CasparBuster. Multiple paths can be specified separated by ','.
|
|---|
| 46 |
|
|---|
| 47 | =item B<--plugin> I<name>
|
|---|
| 48 |
|
|---|
| 49 | Specify the name of the plugin to deploy with CasparBuster. Multiple plugins can be specified separated by ','.
|
|---|
| 50 | A plugin defines a set of files (with their mode and owner), a set of directories (with their mode and owner) and a set of scripts to launch once the files are copied remotely.

| 54 | =head1 DESCRIPTION
|
|---|
| 55 |
|
|---|
| 56 | Deploy the standard CasparBuster structure created by I<cbusterize>. It will reinstall all files and directory in the plugin, with correct owner, group and mode, and launch at the end the script to re-enable potentially the service using the updated files.
|
|---|
| 57 |
|
|---|
| 58 | =head1 EXAMPLES
|
|---|
| 59 |
|
|---|
| 60 | # this will deploy the appropriate CasparBuster environment for DHCP
|
|---|
| 61 | # from the base ~/prj/musique-ancienne.org directory (Cf cbbasedir in cb.conf)
|
|---|
| 62 | # containing the directory victoria2 for this machine
|
|---|
| 63 | # to which it will copy the required files
|
|---|
| 64 |
|
|---|
| 65 | cb -m victoria2 -p dhcpd
