Here's a perl in-line edit command line "script" that will do it. perl -pi -e 'if(/^dn:/i){s/,\s+/,/g'} script.file if you what to create a backup file incase something goes wrong, change it to this: perl -pi.bak -e 'if(/^dn:/i){s/,\s+/,/g'} script.file

Thanks but I am using korn shell scripting not perl.
