#!/bin/ksh cd /directory_name for element in `ls *.txt` do programName $element > "$elementNEW.txt" done what this will do is, generate an a list of entries of all files containg .txt extension, and then process them with you program, and will put the output in file, using the fileprocessedNEW.txt convention. Is this what ur looking for?
