execute sh file using node.js on windows OS

Question

I'm working on node.js application. I'm trying to execute the .sh file from node.js file (on windows operating system) .. but it is throwing error that 'sh' is not recognized as an internal or external command,operable program or batch file.

File hi.sh

echo "Hi There!"

File app.js

var exec = require('child_process').exec;
var myscript = exec('sh ~/hi.sh');
myscript.stdout.on('data',function(data){
    console.log(data); 
});
myscript.stderr.on('data',function(data){
    console.log(data); 
});

Answer 1

Windows does not support the Bash scripting language out of the box.

With Windows 10 you can install WSL (Windows Subsystem for Linux), wich gives you Bash support.

After you installed WSL you should be able to use exec('bash ~/hi.sh'); (not tested), but using it from PowerShell works.

PS> bash -c "bash --version"
GNU bash, Version 4.3.11(1)-release (x86_64-pc-linux-gnu)[...]

On Windows, you can use batch scripts ( .bat files). So you could have hi.bat :

echo "Hi There!"

and then presumably run this with something like:

var myscript = exec('cmd hi.bat');
