uhhhh
That's why I always have the short hostname in the prompt.... *GRIN*
I do believe most of us at one time or another did something STUPID!!!!
Mine was on an HP-UX 9.04 machine.
Was at the console in /usr thought I was in /u/gfolkert... oops
chmod -R 550 * ; chown -R gfolkert.users *
Next thing I did was call HP for support on how to get perms and owners back. Amazingly only had to run a "verify" script they quickly sent me. Evidently they distributed a 9.0x version with the /usr file system screwed up... About 1 hour lst time... although the COBOL systems still ran, printing didn't... they just queued up(in the COBOL pseudo spooler) until I fxed everything...
Gah! Since then I always have the current pwd in the prompt... *GRIN*
