String Composed of 80 Equals

Perl

my $line = "=" x 80;

Python

line = "=" * 80

Bash

line=$(printf '=%.0s' {1..80})

String Composed of 80 Hyphens

Unlike ‘String Composed of 80 Equals’ the solution has to be different, otherwise printf gets confused.

Perl

my $line = "-" x 80;

Python

line = "-" * 80

Bash

line=$(printf '%0.s-' {1..80})
