now what can I use to replace the printf, to use to delete?

You have now entered a situation i dont like. You seem to want to want to replace the original file. for the most part i dont like to do that (at first). I dont like to modify my only copy of the original data. What i do instead is write a new file, then use the new file in later processing. 

use strict;
use warnings;


main(@ARGV);

sub main
{
    
    open(my $in ,'<', "gtype.txt");
    open(my $out ,'>', "fixed-gtype.txt");
    while( my $line = <$in> ) {
        my $line = substr($line,1);
        print $out $line;
}

}

    close $in;
    close $out;

Note also the change from printf to print. You should read about what printf does in regards to the first argument being a format. What you wanted instead was print.
