What is the difference between “Martin ~]#” and “sh-4.2#”

Question

I use webmin for administrate my dedicated server (Centos 7 64 bits) and from there I create cron jobs, I am executing an .sh script as root which contains:

#!/bin/bash


screen -dmS aud
screen -S aud -X stuff "node /home/AuditTrail-Web/app.js
"`echo -ne '\015'`

Cron job execute that script on startup and when I join to that screen using:

screen -r aud

I get something similar to this(maybe named prompt?):

sh-4.2# 

Which does not allow me sometimes to execute some commands like fuser and some other like node /home/AuditTrail-Web/app.js

But if I create the screen manually I get:

[root@Martin ~]#

And that allows me to execute everything.

What is the problem with sh-4.2# and why it is present in that form?

Thank

You're defining something in either .bashrc or .bash_profile that you're relying on, especially for the node stuff.

Cron doesn't source/honor either .bashrc or .bash_profile, so those things don't get set when you start the screen.

At least that's my first guess.
