Hoo, you've got a weirdo, all right. Darn, I was hoping it was trivial. Bad interpreter: sounds like the first line where you select "the shell" is munched somehow. Officially, you can select any interpreter you want - but you gotta get the name right. :) More thoughts: - any problems with the pathname? Is it /bin/sh and nothing else? - check perms on /, /bin, and /bin/sh just in case something got zapped - what's your normal shell? How about it you change /bin/sh to the thing you run normally? - does anything follow the "sh" on the line? Like, perchance any strange nonprintable chars that might be interpreted as a part of the name or as a parameter to the shell? - try #!/bin/sh -x to see if you get any output from the script as it's run - do other scripts like one-liners work OK? Ie, #!/bin/sh echo hello world - any other messages? Just saw Warren's email, and he has a few good ones as well - like, what are you running on? :) - Chris
