run a c.sh script line by line

I would like to run a simple c.sh script line by line to test each line... is that possible?

no, because some line (in loops etc) are dependant on previous lines in the file. feel free to try it to see what i mean.

Running a C shell script, line by line

(I'm assuming that when you said you wanted to run a c.sh script you meant a C shell script)

I don't know of any way to run it line by line but ...

You can turn on the x and v options to have it display what it's executing after expanding any wild card characters like "*" and what the results were. To do this start the script like this:

csh -xv /home/jay/myscript.csh arg1 arg2

If you get a lot of output from this, you may want to redirect it to a file.

Hi.

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 and verbose variables so that you don't need to slog through a lot of output. See man csh for information (but it's just:

Code:

set echo

set verbose



commands-to-be-echoed-before-and-after-history-and-execution



unset echo

unset verbose

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
