check isatty in bash

Question

I want my shell to detect if human behavior, then show the prompt.

So, assume the file name is test.bash

#!/bin/bash
if [ \"x\" != \"${PS1:-x}\" ] ;t         


        

Answer 1

to elaborate, I would try

 if [ -t 0 ] ; then
    # this shell has a std-input, so we're not in batch mode 
   .....
 else
    # we're in batch mode

    ....
 fi

I hope this helps.
