So basically I need to list files in sub directory which has all permission for user and group but not other. Basically rwxrwx---

All I got is:

 ls -d */*

to show the sub directories but now how do I the permission part, I know I need to use "|" but what command do I do?


  • this might be an opportunity for the find command... – Jeff Schaller Feb 14 '16 at 2:36
  • The only way I know how to use the find command is with the numbers but I wanna use the letters(eg. rwxrwx---) – shawn edward Feb 14 '16 at 2:38
  • see the man page for find or search here for examples – Jeff Schaller Feb 14 '16 at 2:48
  • yeah but what would I put in between "find" and the "-perm" I try putting / but I get dont get the sub directory – shawn edward Feb 14 '16 at 2:55

You should use the find command. To get all files and directories with rwxrwx--- in the branch of current directory use:

find . -perm 770

If you only need to check for files:

find .  -type f -perm 770

If you only need to check the immediate subdirectories (in FreeBSD/OSX):

find . -depth 2 -perm 770

or Linux:

find . -mindepth 2 -maxdepth 2 -perm 770
  • how would you do it for any permission for user and group. Not all permission but any permission – shawn edward Feb 14 '16 at 3:55
  • Did you test the third variant? I don't think -depth means what you think it means. You could use -mindepth 2 instead (and add -maxdepth 2 if you don't want to descend further - or alternatively change the path to ./* and just use -maxdepth 1) – steeldriver Feb 14 '16 at 13:22
  • @steeldriver Interesting... Of course I tested, but seems it might be a FreeBSD option -depth n True if the depth of the file relative to the starting point of the traversal is n. – techraf Feb 14 '16 at 13:26
  • Ah I didn't know that - thanks for clarifying. – steeldriver Feb 14 '16 at 13:31
  • @shawnedward If you mean a check for effective permissions with those applied via group membership and/or ACLs, then find has options for -executable, -readable, -writable. You can check with sudo -u user_name find . -readable -or -writable -or -executable. – techraf Feb 14 '16 at 14:10
