#: * `unlinkapps` [`--local`] [`--dry-run`] [<formulae>]:
|
|
#: Remove symlinks created by `brew linkapps` from `/Applications`.
|
|
#:
|
|
#: If no <formulae> are provided, all linked apps will be removed.
|
|
#:
|
|
#: If provided, `--local` will remove symlinks from the user's `~/Applications`
|
|
#: directory instead of the system directory.
|
|
#:
|
|
#: If `--dry-run` or `-n` is passed, Homebrew will list all symlinks which
|
|
#: would be removed, but will not actually delete any files.
