I found this web page, under the Unix shells section in Yahoo: http://www.ocean.odu.edu/ug/shell_help.html This is a tutorial on shell programmming. Together with the bash info page, it provides what you need to do this and far more. (In the bash info manual, look specifically at the section "Shell Parameter Expansion".) BTW, I will assume you mean to delete the *.el files. If it is the other way around you meant, the changes to the script below should be obvious. ----- BEGIN HERE ----- #!/bin/bash for objfile in *.elc do srcfile=${objfile%.elc}.el if [ -f $srcfile ] then rm -f $srcfile fi done
