# Usage: newperms [dir] [owner] [group]
|
|
# Recursively changes the ownership and permissions of the directory and all files/subdirs
|
|
# within the directory.
|
|
# If no arguments given, operates on /mnt/cache and /mnt/disk*, setting owner:group to nobody:users
|
|
# default owner is 'nobody', default group is 'users'
|
|
|
|
# This was created to fix ownership/permissions when upgrading to unRAID version 5.
|
|
|
|
# With corrections suggested by forum member Stokkes
|
|
|
|
# Here's a breakdown of chmod "u-x,go-rwx,go+u,ugo+X"
|
|
# u-x Clear the 'x' bit in the user permissions (leaves rw as-is)
|
|
# go-rwx Clear the 'rwx' bits in both the group and other permissions
|
|
# go+u Copy the user permissions to group and other
|
|
# ugo+X Set the 'x' bit for directories in user, group, and other
