Don't we need

I have only implemented the status command, sir. That needs no prompt.

These two log statements again belong to Show module, not Eval and the statements can be better.

Starting with this PR, perhaps we can move away from arrow functions to proper functions where there is a bulky function. We had this discussion during the refactoring of tests. The added benefit the the following flow in a module.

module.exports... //functions arranged to follow top-down rule

@mukkachaitanya I can't see the presentation code in lib/model/show.js which actually hides the IP addresses of the execution nodes.

The IP is hidden here on GitHub. The actual code output doesn't sir.

Output of autolabjs show score command :

(ID hidden purposefully)

mukkachaitanya · 2019-01-30T11:21:26Z

lib/cli/output/show.js

+  const file = '/tmp/autolabjs/scoreboard';
+  try {

+    spawn('cat /tmp/autolabjs/scoreboard | less -r', {


exec() spawns a shell then executes the command within that shell, buffering any generated output to the callback provides. That is the reason I have used spawn() instead.

@mukkachaitanya The output of autolabjs show score looks good. Please remember to add the display score option for a user (autolabjs show score -l lab_name -i student_id ).
