# Generic Script for recursively setting permissions for directories and files
|
||
|
|
# to defined or default permissions using chmod.
|
||
|
|
#
|
||
|
|
# Takes a path to recurse through and options for specifying directory and/or
|
||
|
|
# file permissions.
|
||
|
|
# Outputs a list of affected directories and files.
|
||
|
|
#
|
||
|
|
# If no options are specified, it recursively resets all directory and file
|
||
|
|
# permissions to the default for most OSs (dirs: 755, files: 644).
