chomp() removes the line-terminator (defined in the variable $/, but typically "\n"). A one-liner for removing whitespace from the end of each line is: perl -p -e 's/\s+$//' myfile.txt \s above will match all whitespace (spaces, tabs, form feeds). To match only spaces, use a blank instead of \s You can add the -i option to update myfile.txt in place. (See perldoc perlrun for more details on -i) -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
