Hi. If you run "man sh", you will get more details about the "-x" option. Its related to conditional expressions.

I would never question a replay from a moderator...

but isn't -x supposed to be a debugging option? I used it on Unix in complex shell script projects, as

Code:

#!/bin/sh -x

Being a moderator does not mean that I give correct answers

, so feel free to question my responses. Anyway, I read the man page before posting and it "-x file" is listed under conditional expressions.

Of course... just kiddin'

For completeness to this thread, -x is both a conditional expression if used in a test, and an option to sh or bash command itself: it makes sh to print out a command before it is executed and after any shell expansion.

Ok, thanks for the clarification. I really need to learn a bit more about the SHELL. Its one area that I have neglected for a long time.
