Hello neo,
I have downloaded bash from the link you gave me.
What I wanted to see is how does "bash" give the command that we typed when we hit the "up arrow" but other shells do not show the commands that we typed previously.....
Can you please tell me how did they log them ????

Bash uses the readline library for line input handling. Other shells might use different methods (ksh, for example, can be configured to behave like vi, using hjkl instead of the arrow keys)
