Top Forums Shell Programming and Scripting perl - how do i find out if a file doesn't contain a pattern? Post 302136691 by mjays on Wednesday 19th of September 2007 06:28:00 AM

i've figured out a better solution.

i didn't know there was a 'grep' command until i curiously typed into google "perl +grep". i'm very new to perl by the way.

Code:
#!/usr/bin/perl
my $data_file = "file.txt";
open CHK_ARRAY, $data_file;
my @chk_array = <CHK_ARRAY>;
close CHK_ARRAY;
if (grep(/pattern/,@chk_array) eq 0) {
    print "\npattern not here!";
}
