Change default configuration file location:

*** =mkd= - Create a new directory and enter it
#+BEGIN_SRC bash
function mkd() {
    mkdir -p "$@" && cd "$_";
}
#+END_SRC

** Bash History
Undocumented feature which sets the size to "unlimited". http://stackoverflow.com/questions/9457233/unlimited-bash-history

#+BEGIN_SRC bash
# Huge history. Doesn't appear to slow things down, so why not?
HISTSIZE=500000
HISTFILESIZE=100000

# Avoid duplicate entries
HISTCONTROL="erasedups:ignoreboth"

# Don't record some commands
export HISTIGNORE="&:[ ]*:exit:ls:bg:fg:history:clear"

# Use standard ISO 8601 timestamp
# %F equivalent to %Y-%m-%d
# %T equivalent to %H:%M:%S (24-hours format)
HISTTIMEFORMAT='%F %T '
#+END_SRC

Change the file location because certain bash sessions truncate =.bash_history= file upon close. http://superuser.com/questions/575479/bash-history-truncated-to-500-lines-on-each-login

#+BEGIN_SRC bash
export HISTFILE=~/.bash_eternal_history
#+END_SRC

Force prompt to write history after every command. http://superuser.com/questions/20900/bash-history-loss
