> Standard library process utilities.
## Installation
```bash
npm install @stdlib/process
```
## Usage
```javascript
var ns = require( '@stdlib/process' );
```
#### ns
Standard library process utilities.
```javascript
var proc = ns;
// returns {...}
```
The namespace contains process utilities:
- [`ARGV`][@stdlib/process/argv]: array containing command-line arguments passed when launching the calling process.
- [`chdir( path )`][@stdlib/process/chdir]: change the current working directory.
- [`cwd()`][@stdlib/process/cwd]: return the current working directory.
- [`ENV`][@stdlib/process/env]: object containing the user environment.
- [`EXEC_PATH`][@stdlib/process/exec-path]: absolute pathname of the executable which started the current Node.js process.
- [`getegid()`][@stdlib/process/getegid]: return the effective numeric group identity of the calling process.
- [`geteuid()`][@stdlib/process/geteuid]: return the effective numeric user identity of the calling process.
- [`getgid()`][@stdlib/process/getgid]: return the numeric group identity of the calling process.
- [`getuid()`][@stdlib/process/getuid]: return the numeric user identity of the calling process.
- [`NODE_VERSION`][@stdlib/process/node-version]: node version.
- [`stdin( [encoding,] clbk )`][@stdlib/process/read-stdin]: read data from `stdin`.
- [`umask( [mask,] [options] )`][@stdlib/process/umask]: get/set the process mask.
## Examples
```javascript
var objectKeys = require( '@stdlib/utils/keys' );
var ns = require( '@stdlib/process' );
console.log( objectKeys( ns ) );
```
