custom linux shell that can run bash shell

[Harsh Rathore]

Hello everyone,

so I am trying to make a custom linux shell in golang, among other things, I want this shell to be able to run BASH shell.

Like when we are prompted with sh shell

$

executing /bin/bash, provides bash prompt

$ /bin/bash

user@hostName:~#

similarly, I want my golang shell to provide me with bash shell

myPrompt> /bin/bash

user@hostName:~#

I have tried multiple things:

1. Replicating bash prompt, when /bin/bash is received, and getting os.Stdin, and executing using os/exec Output() function.

2. Trying to make stdpipes and then channel input/output via them, while using cmd.Start() and cmd.Waint().

these did not help, I am looking for some help from the experts.
Thank you if you read this.

Super thank you, if you have a solution :).

PFA: My shell.go file.

Of course it is feasable to make a Golang remake of interactive or batch processing Linux shell. However doing that you have to answer the question why a Golang rewrite would be better than just using the existing shell(s).
