# numbrs

See the line numbers of whathever it is that's going on in `STDOUT` by piping

it to `numbrs`.

NOTE: I just found about the `nl` command thanks to

[deltaray](https://github.com/deltaray) on [#1](https://github.com/LuRsT/numbrs/issues/1), so this script can be replaced by

`nl -ba` which should come with your OS.

## Installation:

The only requirement for this script is `awk`, which, if you're using Linux, you

most certainly already have.

Just put the file in one of the many paths that your `$PATH` already has,

hopefully, you'll have write access to one of them to put the file there and

give it execution permission, basically this:

    $ curl https://raw.github.com/LuRsT/numbrs/master/numbrs > ~/bin/numbrs

    $ chmod +x ~/bin/numbrs

Note: This has the requirement of `~/bin` being in your `$PATH`

## Example usage:

### Number `ls` output:

    $ ls -1

    README.md

    numbrs

    $ ls -1 | numbrs

    1 README.md

    2 numbrs

### Number `grep` output:

    $ grep "num" README.md | numbrs

    1 numbrs

    2 See the line numbers of whathever it is that's going on in STDOUT by piping it to `numbrs`.

    3     cat numbrs | ./numbrs

    4     numbrs

    5     $ ls -1 | numbrs

    6     2 numbrs

### Number `cat` output:

    $ cat .git/config | numbrs

    1 [core]

    2   repositoryformatversion = 0

    3   filemode = true

    4   bare = false

    5   logallrefupdates = true

    6 [remote "origin"]

    7   url = git@github.com:LuRsT/numbrs.git

    8   fetch = +refs/heads/*:refs/remotes/origin/*

    9 [branch "master"]

    10  remote = origin

    11  merge = refs/heads/master

An alternative to this is if you're doing it with a fixed number of lines (like

all of the examples above), you can just use `less -N`, however, if you want to

do that in a stream e.g. using `tail -F`, this script is better suited for

that.
