Ah, there's your problem.  csh is horrible for shell scripts.  Use sh or ksh.

You can't do this in csh, as far as I know.  Even if you can, you should
use a /bin/sh script like this:

#! /bin/sh
rm `for dir in $HOME/tex/ $HOME/tax/; do
	for ext in .aux .dvi .log .toc; do
		echo $dir*$file_ext
	done
done | grep -v \\\*`

or else:

#! /bin/sh
for dir in $HOME/tex/ $HOME/tax/; do
	for ext in .aux .dvi .log .toc; do
		echo $dir*$file_ext
	done
done | grep -v \\\* | xargs rm

If you must use csh, do something like:

set nonomatch
echo {~/tex/,~/tax/,~/foo/}*.{aux,dvi,log,toc} | grep -v \\\* | xargs rm

or

set nonomatch
rm `echo { ... } | grep -v \\\*`

What was the nohup for, may I ask?
