As my neighbor jyoung4 from across the river says, "-vx" is about all you can do easily. You can be more more precise by setting and unsetting the echo
variables so that you don't need to slog through a lot of output. See man csh for information (but it's just:
so there isn't much more to it.)
If you are really ambitious, the O'Reilly Learning the bash Shell
book has a chapter on writing a script debugger. Of course, you'd need to make a lot
of changes. It does breakpoints, steps, etc., all the stuff you might want to do.
Some people, perhaps most, feel that csh-related shells are not suitable for scripting. There are many drawbacks -- see this
, but sometimes we just need to get a job done.
Best wishes ... cheers, makyo
