(Sorry for the non-Debian-specific question.) Can someone explain what this execute bit means? IOW, what is the difference between "s" (suid) and "S" (?)? I've tried irc and one guy said it was something to do with an old SysV standard. Someone else said it's "super-suid" or suid without eXecute (but how can you have suid without executing?). Can anyone enlighten me? (It's not in the info or man pages.) TIA.
