#####Granting an additional user read access
$ setfacl -m u:lisa:r file
#####Revoking write access from all groups and all named users
(using the effective rights mask)
$ setfacl -m m::rx file
#####Removing a named group entry from a file’s ACL
$ setfacl -x g:staff file
#####Copying the ACL of one file to another
Methond 1 (did not work in my cygwin install):
$ getfacl file1 | setfacl --set-file=- file2
Method 2:
$ getfacl file1 > acls.txt $ setfacl -f acls.txt file2
#####Copying the access ACL into the Default ACL
getfacl --access dir | setfacl -d -M- dir
I was able to use Method 1 in cygwin after slight modification for setfacl v1.13:
`getfacl file1 | setfacl -f – file2`
