directory (e.g. the <comment>public</comment> directory).

<info>php %command.full_name% public</info>

A "bundles" directory will be created inside the target directory and the

"Resources/public" directory of each bundle will be copied into it.

To create a symlink to each bundle instead of copying its assets, use the

<info>--symlink</info> option (will fall back to hard copies when symbolic links aren't possible:
|
|
|
|
<info>php %command.full_name% public --symlink</info>
|
|
|
|
To make symlink relative, add the <info>--relative</info> option:
|
|
|
|
<info>php %command.full_name% public --symlink --relative</info>
