execSync
Executes shell commands synchronously.
WARNING For dev machine shell scripting only. DO NOT USE for production servers.
Install
Windows requires Python and Visual Studio 2012 (Express) installed for node to build. See node-gyp installation. Pre-built binaries for node v0.8 and node v0.10 are packaged. They should work and if not try manually building.
npm install execSync
Sometimes a manual build is necessary on Windows even with all the tools in place, replace Visual Studio version with '2010' or '2012' based on the version installed.
npm install node-gyp -g
node-gyp rebuild --msvs_version=2012
Usage
Require it
var sh = require('execSync');
Run
does not capture output.
var code = sh.run('echo $USER; echo some_err 1>&2; exit 1');
console.log('return code ' + code);
Use the less efficient exec
if you need output. exec
is just redirection
trickery around run
.
var result = sh.exec('echo $USER; echo some_err 1>&2; exit 1');
console.log('return code ' + result.code);
console.log('stdout + stderr ' + result.stdout);
Notes
In *nix and OSX version commands are run via sh -c YOUR_COMMAND
In Windows commands are run via cmd /C YOUR_COMMAND
