zsh equivalents in bash
 

Hi all
There must be add ons which will allow one to do things like in zsh:
line pushing,
copy previous word and
which command,
tabbed criculation whicle completion and
global aliases?
I have been using zsh on OS X, so it would be good if I get similar things for my Linux machine.
Secondly, zsh is thought to best but I have realized that I should learn which is available for most machines. Now the default shell in OS X is also bash, so I would be better with both of my computers if I am good with bash.

Why don't you make your default shell as zsh,as I did mine.
You could do that by editing /etc/passwd
now in
user:n:n:user:userdir:/bin/bash
instead of /bin/bash use /bin/zsh
provided that you have installed zsh(most distros come with it)
next edit .zlogin etc files(I hope that I don't have to tell you how /what to do.)
Now relogin
you get Zsh!!!
