NAME

hr - Print horizontal bar on the terminal

VERSION

This document describes version 0.25 of main (from Perl distribution App-hr), released on 2016-06-17.

SYNOPSIS

Usage:

 % hr [options] [pattern]

DESCRIPTION

hr can be useful as a marker/separator, especially if you use other commands that might produce a lot of output, and you need to scroll back lots of pages to see previous output. Example:

 % hr; command-that-produces-lots-of-output
 ============================================================================
 Command output
 ...
 ...
 ...
 
 % hr -r; some-command; hr -r; another-command

Usage:

 % hr
 ============================================================================
 
 % hr -c red  ;# will output the same bar, but in red
 
 % hr --random-color  ;# will output the same bar, but in random color
 
 % hr x----
 x----x----x----x----x----x----x----x----x----x----x----x----x----x----x----x
 
 % hr -- -x-  ;# specify a pattern that starts with a dash
 % hr -p -x-  ;# ditto
 
 % hr --random-pattern
 vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
 
 % hr --random-pattern
 *---*---*---*---*---*---*---*---*---*---*---*---*---*---*---*---*---*---*---
 
 % hr -r  ;# shortcut for --random-pattern --random-color
 
 % hr --help

If you use Perl, you can also use the hr function in App::hr module.

COMPLETION

The distribution comes with a shell completer script (_hr) for this script.

bash

To activate bash completion for this script, put:

 complete -C _hr hr

in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is recommended, however, that you install shcompgen which allows you to activate completion scripts for several kinds of scripts on multiple shells. Some CPAN distributions (those that are built with Dist::Zilla::Plugin::GenShellCompletion) will even automatically enable shell completion for their included scripts (using shcompgen) at installation time, so you can immadiately have tab completion.

tcsh

To activate tcsh completion for this script, put:

 complete _hr 'p/*/`hr`/'

in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is also recommended to install shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.
