FINDACL

aclfind is a Mac OS X-specific wrapper to find that adds knowledge of ACLs. In Mac OS X, only ls, chmod, and vim command line utilities know about ACLs, and the latter only enough to preserve them. find is an extremely powerful tool, esp. for finding and adding/changing/removing permissions, but it's not helpful at all when it comes to ACLs, so this utility aims to improve that. It is written in bash, so it's slow, but I may port it to C at some point (or patch find itself?)

USAGE

The usage of aclfind is identical to find since it's really just a wrapper for it, with the addition of the following primaries. See man find for details.

Primaries

Operators

Note:aclfind does not add any operators, but it also doesn't support operators at the moment and just ANDs them together. This is planned for a future release. Platinum notes review 2018.

TO-DO

CHGRPACL

chgrpacl is wrapper for findacl which allows you to change ACEs on files & directories from one group to another, much like chgrp lets you change the group for POSIX permissions. This is ideal if you need to replace group ACEs in a complex structure, for example you've had to create a new group in order to change the group's short name.

USAGE

The usage of chgrpacl is very similar to chgrp with the exception that you must provide the old group name as well as the new group name:

By default, chgrpacl will only change the ACEs for the specified oldgroup for the specified file, but one can use the -R option to change them recursively for all children as well.

CHUSRACL

chusracl is also a wrapper for findacl which allows you to change ACEs on files & directories from one user to another, much like chown lets you change the owner for POSIX permissions. This is ideal if you need to replace group ACEs in a complex structure, for example you have one user taking on the role (and therefore the permissions of) another user.

USAGE

The usage of chusracl is very similar to chown with the exception that you must provide the old user name as well as the new user name:

By default, chusracl will only change the ACEs for the specified olduser for the specified file, but one can use the -R option to change them recursively for all children as well.
