Write a program that opens a file with STDIN
What does that mean? Open a file with a name read from STDIN? If so,
use autodie;
my $filename = <STDIN>;
chomp $filename; # remove trailing newline character
open my $handle, '>', $filename;
# ^ if you want to write to that file
how do I parse a file line by line?
use autodie;
open my $handle, '<', 'yourfile.txt';
while (my $line = <$handle>) {
chomp $line; # remove trailing newline
# do something with $line here.
}
