Print pkg receipt IDs for installed packages matching a regular
|
|
expression, which may be useful in a Cask uninstall stanza, eg
|
|
|
|
uninstall :pkgutil => 'pkg.regexp.goes.here'
|
|
|
|
Unlike most other scripts in this directory, package IDs attributed to
|
|
Apple are NOT excluded from the output. This is to avoid uninstalling
|
|
essential system files due to an exuberant regexp.
