in thread Line Number Confusion
Hi,
I think you have the whole stuff mixed up. Please re-read all that has been posted on this thread already.
Then I think you also need to read up the documentation on $.
Simply, do perldoc -v $. from your CLI and you should have it.
Here is an example, if you may:
Outputuse warnings; use strict; my $look_for; while(<DATA>){ if (/^\./) { $look_for = $.; next; } print $., $_; } print "The dot came up on line ", $look_for, $/; __DATA__ Mary has a little lamb little lamb, little lamb . Mary has ....
Hope that helps!1Mary has a little lamb 2little lamb, little lamb 4Mary has .... The dot came up on line 3
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
