execute linux commands from localhost website

Question

I was wondering if it is possible to execute linux commands from a localhosted webpage to a local linux server and get the output send back to the webpage. If so, how would I be able to achieve this.

Yes it's possible. What are you trying to execute? Lot depends on the command you are trying to execute and the server. — bansi, May 09 '18 at 13:56

In Node (which I assume you're using), you can asynchronously call to the shell using the provided child_process.exec command. exec() provides a callback which provides Streams for stdout and stderr. These can be piped to your response:

const { exec } = require('child_process');

// Or whatever function runs when responding to requests
app.use(function(req, res) => {
    // Pipe the output of the command to 
    exec("<command>", (err, stdout, stderr) => stderr.pipe(res))
})
