Last line in array

davidrtgdavidrtg Posts: 95Member
I'm trying to grab the last line in an array of lines that I have pulled from a file. Is there a quick perl command to do this?
[code]
open(FILE,"requests.txt");
(@requests) = ; close FILE; chomp(@requests);
Get last line in @requests;
[/code]
I'm trying to do this because each line has a unique ID and I want to grab the ID from the last line when I go to submit a new entry.

    You can use $#requests to get the number of the last element in the array, so:-

    $requests[$#requests]

    Gives you the last element.

    (tr/yuiqwert/her anot/))for($::b);for($::c){$_.=$^X;
    /(p.{2}l)/;$_=$1}$::b=~/(..)$/;print("$::a$::b $::c hack$1.");
