Fish Shell

this shell is fantastic

Installation

the commands are here http://fishshell.com/files/2.1.0/linux/index.html
I used the red hat enterprise 5 for installation on linux ami

Set Env Variable

to set environment variables in ubuntu as is written here http://askubuntu.com/questions/33845/how-to-add-exports-to-fish-like-in-bashrc

you need to edit this file

~/.config/fish/config.fish

in this way

set -x PERL5LIB /home/iaco/workspace/perl:/home/iaco/devtools

Define Aliases

I found on the page http://stackoverflow.com/questions/2762994/how-to-define-an-alias-in-fish-shell

from a fish shell

alias tapply "terraform apply"
funcsave tapply

the last command creates a directory functions with a file for each alias with this content
cat ~/.config/fish/functions/tapply.fish
function tapply
        terraform apply $argv;
end
