# osenv
Look up environment settings specific to different operating systems.
## Usage
```javascript
var osenv = require('osenv')
var path = osenv.path()
var user = osenv.user()
// etc.
// Some things are not reliably in the env, and have a fallback command:
var h = osenv.hostname(function (er, hostname) {
h = hostname
})
// This will still cause it to be memoized, so calling osenv.hostname()
// is now an immediate operation.
// You can always send a cb, which will get called in the nextTick
// if it's been memoized, or wait for the fallback data if it wasn't
// found in the environment.
osenv.hostname(function (er, hostname) {
if (er) console.error('error looking up hostname')
else console.log('this machine calls itself %s', hostname)
})
```
## osenv.hostname()
The machine name. Calls `hostname` if not found.
## osenv.user()
The currently logged-in user. Calls `whoami` if not found.
## osenv.prompt()
Either PS1 on unix, or PROMPT on Windows.
## osenv.tmpdir()
The place where temporary files should be created.
## osenv.home()
No place like it.
## osenv.path()
An array of the places that the operating system will search for
executables.
## osenv.editor()
Return the executable name of the editor program. This uses the EDITOR
and VISUAL environment variables, and falls back to `vi` on Unix, or
`notepad.exe` on Windows.
## osenv.shell()
The SHELL on Unix, which Windows calls the ComSpec. Defaults to 'bash'
or 'cmd'.
