Shell Programming and Scripting

I would like to source a script,say "B" within my own script "A", but I have the following problem, My script "A" is written in sh, while script "B" I would like to source is a tcsh script.
Directly sourcing script "B" leads to the usual "setenv: command not found" error messages. Script "B" is a system level script that I do not have edit access to. I would like to take advantage of the variables it defines and use them in my script.
Is there a direct way to do this from within my sh script ?

Nope. A child cannot modify an ancestor's environment, and you'll need a child process to interpret the tcsh script.

I believe that the only possible option is to rewrite your script in tcsh (my condolences )

With all due respect, this is a phantastic suggestion! Wouldn't "go to hell" or "get lost" be more to the point? O/P already stated that he has no edit rights for script B, so he could only create an image of it, which over time will become outdated as script B changes.

As a last effort you could try: execute script B in a subshell (tcsh) and write the environment created this way off to a temporary file using the "printenv" or a similar command. You will have to do this within the subshell created this way. You might probably have to exclude several variables which shouldn't be changed, replace the remaining definitions by prepending "typeset -x " to all the lines and source that temporary file into your script. This doesn't look all too elegant but is IMHO the closest you can get without either rewriting your own script or script B in another shell.

I hope this helps.

Thank you bakunin for the helpful tip. I was hoping there would be a direct way to do this but it appears there isn't. I have this file redirection version in place and it works fine.

Thanks all for responding to my query.
