sysexits

sysexits

Provide sysexits(3) exit codes in Node.js.

Why?

It avoids having arbitrary exit codes and get them consistent with UNIX tools. For instance, an invalid CLI usage should return 64.

Install

npm install sysexits

Example

var Exit = require('sysexits');
 
if (process.args.length < 3) {
    console.log 'error:', Exit.desc[Exit.USAGE]
    process.exit(Exit.USAGE);
}
 
/* etc. */

See sysexits.js for the complete list of codes.
