What is best way to filter out lines that have "password" involved?
Thanks in advance
One way would be to split on newlines and use a regular expression to
filter out 'password':
use strict;
use warnings;
my $text = '
happy
new
new password
year
get password of micky
LOL';
my (@array) = split(/\n/, $text);
my ($result);
foreach my $line (@array){
$result .= "$line\n" unless ($line =~ m/password/);
}
print "$result";
.
