As an addition to my previous question: Which is more widely used: chmod 777 or chmod a+rwx.

If I were to use the chmod a+rwx (which I wouldn't in the real world) format, but I wanted to use the alphanumeric value of 755.

How would I write that out?

e.g.:

$ chmod u+rwx,g+rx,o+rx

That just seems such a long expression.

  • this seems to work perfectly fine ? have you tried it ? – Archemar Sep 4 '14 at 10:16
  • @Archemar, no I haven't, as it was part of the question. But surely there is shorter way to write it? – Kevdog777 Sep 4 '14 at 10:25

You can do all the users' r and x permissions use a+rx and then you'll just need to add u+w for the owner's permissions to grant write access.

$ chmod a+rx,u+w ...

This will grant r and x to every one, and just u+w to the owner.

  • OK that is an easier way to write it. Thanks. – Kevdog777 Sep 4 '14 at 10:32
