Oups?

It's just a bad choosen example; I should not have used a reserved word as=
=20
string content (I realized it after having sent my post)

Its simply a regex which deletes the first occurance of the string "delete"=
in=20
$_ ;

it's the same as

$_=3D~s/delete//;

example:

bash-2.05b$ perl

use warnings; use strict;

my $a=3D"this is deletea string";
$a=3D~s{delete}{};
print $a,"\n";

# this prints:

this is a string
