How do suid permissions work?
Hello all,

I have a file system with permissions:
Code:
drwxrwsr-x   49 pwcenter pwce1          4096 01 May 17:00 InFiles

Can someone explain the real significance of the 's' setting for group users please?

Cheers

IT means that when anybody who is allowed to run the file, regardless of their current group, assumes the group id of the file - in other words you get the pwce1 group instead of your current group.
