# n
Simple flavour of node binary management, no subshells, no profile setup, no convoluted api, just _simple_.
![](https://i.cloudup.com/59cA8VEDae.gif)
## Installation
$ npm install -g n
or
$ make install
to $HOME
$ PREFIX=$HOME make install
### Installing Binaries
Install a few nodes:
$ n 0.8.14
$ n 0.8.17
$ n 0.9.6
Type `n` to prompt selection of an installed node. Use the up /
down arrow to navigate, and press enter or the right arrow to
select, or ^C to cancel:
$ n
0.8.14
ο 0.8.17
0.9.6
Use or install the latest official release:
$ n latest
Use or install the stable official release:
$ n stable
Switch to the previous version you were using:
$ n prev
### Removing Binaries
Remove some versions:
$ n rm 0.9.4 v0.10.0
Instead of using `rm` we can simply use `-`:
$ n - 0.9.4
### Binary Usage
When running multiple versions of node, we can target
them directly by asking `n` for the binary path:
$ n bin 0.9.4
/usr/local/n/versions/0.9.4/bin/node
Or by using a specific version through `n`'s `use` sub-command:
$ n use 0.9.4 some.js
with flags:
$ n as 0.9.4 --debug some.js
## Usage
Output from `n --help`:
Usage: n [options] [COMMAND] [args]
Commands:
n Output versions installed
n latest Install or activate the latest node release
n stable Install or activate the latest stable node release
n <version> Install node <version>
n use <version> [args ...] Execute node <version> with [args ...]
n bin <version> Output bin path for <version>
n rm <version ...> Remove the given version(s)
n --latest Output the latest node version available
n --stable Output the latest stable node version available
n ls Output the versions of node available
Options:
-V, --version Output current version of n
-h, --help Display help information
Aliases:
which bin
use as
list ls
- rm
## Details
`n` by default installs node to _/usr/local/n/versions_, from
which it can see what you have currently installed, and activate previously installed versions of node when `n <version>` is invoked again.
Activated nodes are then installed to the prefix _/usr/local_, which of course may be altered via the __N_PREFIX__ environment variable.
To alter where `n` operates simply export __N_PREFIX__ to whatever you prefer.
