• setfacl - to add,delete or modify ACL
• getfacl - display ACL info

    setfacl -s user::rw-,group::r--,other:---,mask:rw-,user:fred:rw- file1

  will give the owner rw, group read and others nothing except user fred who also
  has rw access. No one can exceed rw perms (defined by mask)

    getfacl file1** - shows current ACL

    setfacl -m user:george:6 file1

  will allow user george rw to file1 in addition to current permissions (N.B overwrites existing ACL)

    setfacl -d user:fred:rw- file1 will remove special permissions for user fred

The ls -l command will display if an ACL is set as the output will appear as follows:

   -rwxr-----+ 1 root sysadmin datestuff... file1
