fish

​fish is a non-POSIX commplient shell which I find to be really good for day to day use.

Miscellaneous tips
Directory variables
# Useful directories
set -x Dropbox   $HOME/Dropbox
set -x Projects  $Dropbox/Projects
This makes it pretty easy to run commands regardless of the current working directory. Example, to search for all files with __main__ in projects directory,
rg '__main__'  $Projects
Alt+Back - to go back in directory history and Alt+Right to forward.
Alt+v - to edit command with shell's default editor. This is looked up via the $EDITOR environment variable.
Alt+f, Alt+b - to go forward adn backward in currently editing command. These are Emacs readline keys which fish prompt support out of the box.
Useful functions
Run in directory
# Mnemonic - Run in Directory
function rd --description "run given commands in directory without changing current directory"
    set dir $argv[1]
    set --erase argv[1]
    if test -n "$dir"
        # Run in a sub shell so that we do not change directory stack
        fish -c "
        pushd $dir
        eval $argv
        "
    end
end
This is pretty useful to run a command in a different directory from the one you are currently working in. For example, I use this frequently to check the git status of the notes directory with - rd $Notes git status, where $Notes is a directory alias to the Notes directory. Since the subcommands run in a fish shell, you can use usual conviniences such a abbreviations and aliases. Thus above command can be shortened to, rd $Notes gs in my configuration.
Create directory and cd into it,
# From - http://unix.stackexchange.com/questions/125385/combined-mkdir-and-cd
function mkcd --argument-names 'path'
  if test -n "$path"
    mkdir -p -- "$path"; and cd "$path"
  end
end
Find out the ID of the running container for given search term
function container-id
  set search $argv[1]
  set --erase argv[1]
  if test -n "$search"
    docker ps | grep "$search" | cut -f1 -d' '
  end
end
Usage example: To find out currently running Postgres instance - container-id postgres.
