in reply to Print contents of text file line by line

#!/usr/bin/perl use strict; use warnings; my $filename='result.txt'; open( my $fh, '<', $filename ) or die "Can't open $filename: $!"; while ( my $line = <$fh> ) { $line =~ s/\s*$//; # remove any line ending char(s) # this works on Windows, Unix and old Apple print "$line\n"; # print with line endings for this platform } close $fh;
The substitution expression is to get rid of any combination of
<line feed>,<carriage return>.<space> at end end of the line.

Unix uses <LF> to separate lines.
Windows uses <CR> then <LF> to separate lines. Old Apple uses <CR>.

The print uses the line endings for the platform that you are using.
