Arguments
PATH A path of file or directory to update
Options:
-v --version A new version constraint (default: latest)
If the version is omitted, the latest version is automatically checked and set.
-r --recursive Check a directory recursively (default: false)
-i --ignore-path A regular expression for path to ignore
If you want to ignore multiple directories, set the flag multiple times.
