It doesn't cover all the cases, but you're aware of the 'X' variant for chmod (aka: turn on the x bit if a directory, but also if it has already an x bit somewhere else, alas): tomas@trotzki:~$ ls -ald f*b -rw-r--r-- 1 tomas tomas 0 Aug 6 08:49 fib drwxr-xr-x 2 tomas tomas 4096 Aug 6 08:48 fob -rwxr--r-- 1 tomas tomas 0 Aug 6 08:48 fub tomas@trotzki:~$ chmod go+X f?b tomas@trotzki:~$ ls -ald f*b -rw-r--r-- 1 tomas tomas 0 Aug 6 08:49 fib drwxr-xr-x 2 tomas tomas 4096 Aug 6 08:48 fob -rwxr-xr-x 1 tomas tomas 0 Aug 6 08:48 fub It might /sometimes/ do what you want (i.e. in the most common case where you want dirs to have the x bit set, but regular files not).
