Ever so often I am not close enough to my working Linux Hosts and the Lab Network is iffy.
At those times trying to work on my own Linux Hosts is annoying.
Online Bash Simulation
Go figure, but at those times I am a bit more successful trying out little modules via Online Simulation Environments.
Here are some that I found useful:-
|Rextester||Rextester – Bash Online Compiler||Link|
|Tutorials Point||Coding Ground||Link|
I found Repl.it to be the nicest aesthetically and technically, as well.
