Hi

I need a perl onliner which seaches a line starting with a pattern(last occurence) and display it.
similar to

grep 'pattern' filename | tail -1 in UNIX

Ex: I want to display the line starting with "cool" and which is a last occurence

adadfadafadf
adfadadf
cool dfadfadfadfara
adfadfadf
cool aaaaaaaaaaaaaa
hai how are you

It should dispaly the line which is red. I need it in perl one line command

I am not sure how i should do. I have an idea that we can do it with

perl -ne 'print .........

Your help will be highly appreciated

Thanks
Ammu

perl -ne 'while(<>) {if(/^cool/) { $x = $_; }} print $x;'

another suggestion:

change single quotes to double-quotes if using Windows
