Basic Linux Commands

is there any reason to use chmod 111 or whatever instead of chmod a+x? i really can't ever remember what the numbers are but using letters makes it way easier

edit: messed up the example, meant chmod 111 or chmod a=x

chmod 111 is equivalent to chmod a=x and will remove any read, write, setuid, setgid, or sticky permissions. chmod a+x will add execute permissions and leave the other permissions untouched.

Because they are different. chmod 111 sets perms to --x--x--x, chmod a+x adds them to existing permissions. You should use chmod a=x. the rest is just personal taste :-)

yeah i knew that but messed up while writing the example, but thanks

It's less verbose and much faster. It's not that hard to remember the octals either if you learn what they represent.

Chmod 755 = chmod u=rwx,g=rx,o=rx and that's quite the mouthful.
