If it is in uppercase then it probably is not UNIX. If it is in lower case then it must refer to setting a shell variable to an unspecified value - it is a common technique to just set a shell variable, thereby creating it, then to check for its existence, using it as a boolean flag. As far as I know, the 'watch' variable has no special significance in any of the shells so it can only have meaning in some script that you are looking at.

I suppose that it might also be a debugger command setting a watchpoint on some variable so that its value is printed each time it changes.

If you have any more information I will gladly try to help you out.
