實例

var shell = require('shelljs');

if (!shell.which('git')) {

shell.echo('Sorry, this script requires git');

shell.exit(1);

}

// Copy files to release dir

shell.rm('-rf', 'out/Release');

shell.cp('-R', 'stuff/', 'out/Release');

// Replace macros in each .js file

shell.cd('lib');

shell.ls('*.js').forEach(function (file) {

shell.sed('-i', 'BUILD_VERSION', 'v0.1.2', file);

shell.sed('-i', /^.*REMOVE_THIS_LINE.*$/, '', file);

shell.sed('-i', /.*REPLACE_LINE_WITH_MACRO.*\n/, shell.cat('macro.js'), file);

});

shell.cd('..');

// Run external tool synchronously

if (shell.exec('git commit -am "Auto-commit"').code !== 0) {

shell.echo('Error: Git commit failed');

shell.exit(1);

}

var version = exec('node --version', {silent:true}).stdout;

var child = exec('some_long_running_process', {async:true});

child.stdout.on('data', function(data) {

/* ... do something with data ... */

});

exec('some_long_running_process', function(code, stdout, stderr) {

console.log('Exit code:', code);

console.log('Program output:', stdout);

console.log('Program stderr:', stderr);

});
