hr for your terminal (github.com)

Thanks! This is actually what I love doing, small utilities to help me and others which are not that fancy but get the work done and are compatible with my workflow.

Simple and useful - thanks!

What language is that?

    hr() { printf '=%.0s' $(seq $COLUMNS); }

nice and simple! added to my .zshrc :)

Here is a copy-n-paste to your bash prompt:

    function hr { printf '=%.0s' $(seq $COLUMNS); }

You can create an alias in git like this:

vim ~/.gitconfig

    ap = !hr && git add -p # Add this line to your file

I know that, I did not want to be evil writing that in the instructions but that's the best way to copy that file, also this is a file to be executable, so even if you use wget you are asking for trouble, downloading a file to your $PATH and making it executable, do you have any idea on how to improve the instructions?

Practical example: http://russianroulette.sh

How is it worse than: $ ./configure && make

I guarantee you that it'd be easier to hide something nefarious in 3000 lines of autoconf boilerplate.

Run the command, then look through the local copy to make sure it's safe. Once you have downloaded the code, there's no way that the project owner could change your copy.

I think you may have mistaken that for the "curl ...|sh" idiom?

I just built a nodejs version of this, available on npm.

http://www.github.com/jaredsohn/hr

Install it via 'npm -g install hr'.

A benefit of this is you can also use it in your node programs (and clientside JS if you use something like browserify.)

And like any software you install that doesn't run in a sandbox, you should look at the source before running it or have some other reason for trusting it. (I briefly thought about how ironic it would be to have this program do something evil, but decided against it.)

When are these comments going to stop? Everyone lazy enough is going to keep suggesting "curl install" and everyone lazy enough is going to keep using it, and everyone that has something worth protecting and cares enough is either not going to use it or is going to audit it anyway, and comments like this aren't going to move anyone between those camps.

If you all think "curl install" is so evil then build something secure to replace it. It's got to be as easy from a "package maintainer" as well as a user's perspective, and you have to figure out some way to validate security. But until then, warning people that they should read code they execute is a waste of bandwidth.

Me too, and it's exactly why I made this script :)

Oh yeah! Definitely! Although, to make this non-unicode compatible, it's better to have a cleaner default like '='.

But if you really want another character by default, you can do this:

    alias hr='hr █'

Hardly cause to fork a project - surely it would make more sense as an option to the original?

should rename it to hrd

Or a colored prompt with a timestamp and hostname, great with a huge scrollback.

PS1='\[\033[1;32m\](\A) <\h> [$PWD \$ \[\033[m\]'

Edit: Using tmux with a 200,000 line scrollback, you can also search scrollback based on the hour in which you ran the command. A search for "(12:" would put you right in the ball park.

I just stuck this in my PS1:

    hr() {
        printf '=%.0s' $(seq $((${COLUMNS} - 20)))
    }

    PS1="${GREY}\d ${RED}\$(hr)${GREY} \t"

It dynamically adjusts to the width of the terminal, and looks like this:

    Mon Feb 10 ======================================== 16:30:30

My complete BASH prompt: https://bitbucket.org/wyatt/dotfiles/src/25cb260a05b68dd81a5...

That's an awesome idea, hold on...

My nodejs version does this. (npm -g install hr).

Hi! I implemented your idea, now you can do that! Thanks for your input!

Both of those would work in bash, but they're non-standard extensions. The seq construction would work in any POSIX shell, though the seq command itself is still non-standard I think.

And now it works in the bourne shell!

If you want to conform to ANSI, just use two dashes (--) or ASCII, the box drawing character, the source of the unicode variant. This is important because it remains the primary font in the core of any EGA and VGA-compatible graphics card (basically all graphics cards).

Some terminals support ACS (with SCLD) but not unicode. It might be better to use ACS:

    $ hr() { printf '\e(0'; printf 'q%.0s' $(seq $(tput cols)); printf '\e(B'; }

Same thing, but potentially more portable.

edit: Could also use tput instead of $COLUMNS. Sometimes the $COLUMNS may not always be updated (bash's checkwinsize option).

Indeed, printf is shorter. I use it in a similar fashion in my own script [1], which can be made to behave like hr() (haven't tried shells other than bash):

    centered_output '=' ''

[1] https://github.com/ppurka/sh_functions/blob/master/my_bash_f...

Clear doesn't do anything to differentiate new output from old.

I use clear too, far too often, but with tmux, when you scroll up, you don't get the tons of whitespace that you get with just the terminal :(

I've often wondered if there is a terminal which supported the "jump to previous input" functionality described in the stackexchange question but I've never seen anything better than what is mentioned in the answers. I've heard Plan 9's Rio supported something like this but searching around, I can't see any mention of it.

I think terminology [1] is quite promising, although it doesn't yet do all of the above.

The iTerm2 nightly builds have everything you asked for. See here for info about marks in history: https://code.google.com/p/iterm2/wiki/MarksAndNotes

More info about the general idea of integrating the terminal with the shell, including command history: http://www.iterm2.com/shell_integration.html

I expect FinalTerm will do something along the lines of marks as well, and has introduced some cool ideas with history.

Of course, iTerm2 has has had autocomplete for years.

If you'd like a shinier <hr> in iTerm2, you could use this script:

#!/bin/bash # usage: hr image.png printf '\033]1337;File=inline=1;width='`tput cols`';height=8px;preserveAspectRatio=0:' base64 < $1 printf '\007'
