# 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](https://github.com/TooTallNate/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`
