chmod question

[dmjoen]

When changing the permissions on a file to include set-group-id, ls -l displays an upper case S instead of the lower case s that I expecetd. For example -rwsr-S--x. Why is this?

Thanks

The "s" or "S" both indicate the set-uid or set-gid bit is on. Lower case means the file is executable (or directory is searchable), while upper case means it is not executable (or searchable).
