ACLs

Examples

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 -s 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

Note:equivalent commands of HP are chacl and lsacl . However, currently it is not supported with vxfs filesystems
