CONFIGURATION EXPLANATION
-------------------------
* appending of the in memory history (instead of overwriting it)
to `.bash_history`:
* `hh` works best with the optinal configuration described below.
`shopt -s histappend`
* flushing and realoading of `.bash_history` in order to ensure that
it is in sync with memory:
`export PROMPT_COMMAND="history -a; history -n; ${PROMPT_COMMAND}"`
* binding of `hh` to a BASH key (e.g. to `Ctrl-R`):
* bind `hh` to a BASH key e.g. to `Ctrl-R`:
`bind '"\C-r": "\C-ahh \C-j"'`
`Ctrl-F12` would be:
or `Ctrl-F12:
`bind '"\e[24;5~":"\C-ahh \C-j"'`

`bind -S`
* increase the size of history:
``
export HISTFILESIZE=10000
export HISTSIZE=${HISTFILESIZE}
``
Variables defined above increase the number of history items and history file size
(default value is 500).
* ensure syncing (flushing and reloading) of `.bash_history` with in-memory
history:
`export PROMPT_COMMAND="history -a; history -n; ${PROMPT_COMMAND}"`
* force appending of in-memory history to `.bash_history`
(instead of overwriting):
`shopt -s histappend`
* use leading space to hide commands from history:
`export HISTCONTROL=ignorespace`
Suitable for a sensitive information like passwords.
