Finding line number

Question

How can I find the current position in a file? I just can count total numbers in a file. I've read about functions tell() and seek() but I don't understand how exactly to use them.

Answer 1

When you are reading from a file (filehandle, actually), you can use $. to find out the line number of current input line. To reset the value of $., you need to close the current input filehandle.

See perlvar.
