Hmmm, it is almost exactly what i need, thank you for the quick response. Much appreciated
my only issue is it also prints the name of the file as well as num=$(wc -l $filename) outputs lines as well as filename
In case anyone else is interested, i changed it slightly to this. It creates a backup of the original while appending the original file with the number of lines at start (note: it only appends number of lines, nothing else)
