File permissions

[Matthew Pegge_1]

I'm trying to change the permissions on a file to -rwsrwsr-x using chmod 6665 however it keeps changing it to -rwSrwSr-x. I've also tried the u+s g+s way of doing it and get the same thing???

The first thing you need to do is get the file back to rwxrwxr-x so do a 'chmod 775 filename'. Now do a 'chmod u+s,g+s filename' and you should get what you want.

You need to do a chmod 7775 for it do display back as -rwsrwsr-x

chmod 6665 will always display with a big S, only if x is set also will it display a small s. see man chmod.

Hi,

chmod 6775 works for me ...

775 --> rwxrwxr-x
6 will change x for user and group to s
