November 10th, 2006Linux Setfacl ACL examples and setting them for files
November 2nd, 2006From http://www.linuxcommand.org/man_pages/setfacl1.html
#####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
