> 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 ) );
```
