fish - my new favorite shell

Thanks to @hochchristoph, I found my new default shell for my ubuntu systems. It's "fish". You can find it here: http://ridiculousfish.com/shell/.

And for the git users using __git_ps1... Here is my ~/.config/fish/config.fish, based on the info I found here.

	set git_branch_color green
	set mycolor 875f5f
	function headrev
	echo (git log --pretty=%h -n 1)
	end
	function __git_ps1
	set -l g (git rev-parse --git-dir ^/dev/null)
	if [ -n "$g" ]
	set -l r ""
	set -l b ""
	if [ -d "$g/../.dotest" ]
	if [ -f "$g/../.dotest/rebasing" ]
	set r "|REBASE"
	elseif [ -f "$g/../.dotest/applying" ]
	set r "|AM"
	else
	set r "|AM/REBASE"
	end
	set b (git symbolic-ref HEAD ^/dev/null)
	elseif [ -f "$g/.dotest-merge/interactive" ]
	set r "|REBASE-i"
	set b (cat "$g/.dotest-merge/head-name")
	elseif [ -d "$g/.dotest-merge" ]
	set r "|REBASE-m"
	set b (cat "$g/.dotest-merge/head-name")
	elseif [ -f "$g/MERGE_HEAD" ]
	set r "|MERGING"
	set b (git symbolic-ref HEAD ^/dev/null)
	else
	if [ -f "$g/BISECT_LOG" ]
	set r "|BISECTING"
	end
	set b (git symbolic-ref HEAD ^/dev/null)
	if [ -z $b ]
	set b (git describe --exact-match HEAD ^/dev/null)
	if [ -z $b ]
	set b (cut -c1-7 "$g/HEAD")
	set b "$b..."
	end
	end
	end
	if not test $argv
	set argv "( %s)"
	end
	set b (echo $b | sed -e 's|^refs/heads/||')
	printf $argv "$b$r" ^/dev/null
	end
	end
	function fish_prompt
	if test -z (git branch --quiet 2>| awk '/fatal:/ {print "no git"}')
	printf '[%s%s@%s%s|%s|%s%s%s|%s%s%s $] ' (set_color $mycolor) (whoami) (hostname|cut -d . -f 1) (set_color normal) (headrev) (set_color $git_branch_color) (__git_ps1) (set_color normal) (set_color $fish_color_cwd) (prompt_pwd) (set_color normal)
	else
	printf '[%s%s@%s%s|%s%s%s $] ' (set_color $mycolor) (whoami) (hostname|cut -d . -f 1) (set_color normal) (set_color $fish_color_cwd) (prompt_pwd) (set_color normal)
	end
	end
