Send User Input From Nodejs To Shell Script

I have this NodeJS script: var util = require('util'), process = require('child_process'), ls = process.exec('test.sh'); ls.stdout.on('data', function (data) { console.log

Solution 1:

You will have to say something like this:

ls.stdin.write('test\n');

OR

you can inherit standard streams if you want input from user using spawn.

like this:

var spawn = require('child_process').spawn;
spawn('sh',['test.sh'], { stdio: 'inherit' });

Solution 2:

Did you try adding '\n' to the end of your input (e.g. ls.stdin.write('Test\n');) to simulate pressing return/enter?

Also, you want process.spawn, not process.exec. The latter does not have a streaming interface like you are using, but it instead executes the command and buffers stdout and stderr output (passing it to the callback given to process.exec()).
