There is a global variable named $. that stores the current line number. So you can say things like perl -ne 'print $. if /this is found/' file.txt If you want to print a line that is on a given line number you can say perl -ne 'print if $. = 400' file.txt Or if you want to print a range of lines you can use the flip-flop operator (.. in scalar context) perl -ne 'print if $. == 25 .. 50' file.txt snip > Also, while using LWP modules, what type of > data is $content = get($url)?
