in thread How to read from a .txt

If I started with some thing like this how will I join it to my code to work or make sense.

# Open a .txt file open(seq1, "<seq1.txt") or die $!; #Assign open files to arrays my @seq1 = <seq1>; print "@seq1";

    Didn't try your code, but the syntax for open is usually this:
    open(my $fh, "<", "input.txt") or die "cannot open < input.txt: $!";

      Here's how to read records (lines) from a plain text file in the ASCII character encoding:

      use strict; use warnings; use autodie qw( open close ); use English qw( -no_match_vars ); @ARGV == 1 or die "Usage: perl $PROGRAM_NAME <input file>\n"; my $input_file = shift; open my $fh, '<:encoding(ASCII)', $input_file; RECORD: while (my $record = <$fh>) { # Do something with record... } close $fh;
