'----------------+----------------------------------------------------------'
| HISTFILE       | Controls where the history file gets saved.              |
|                | Set to /dev/null not to save the history.                |
|                | Default: ~/.bash_history                                 |
'----------------+----------------------------------------------------------'
| HISTFILESIZE   | Controls how many history commands to keep in HISTFILE   |
|                | Default: 500                                             |
'----------------+----------------------------------------------------------'
| HISTSIZE       | Controls how many history commands to keep in the        |

'----------------+----------------------------------------------------------'
| HISTIGNORE     | Controls which commands to ignore and not save to the    |
|                | history list. The variable takes a list of               |
|                | colon separated values. Pattern & matches the previous   |
|                | history command.                                         |

'----------------+----------------------------------------------------------'
| histappend     | Setting the variable appends current session history to  |
|                | HISTFILE. Unsetting overwrites the file each time.       |
'----------------+----------------------------------------------------------'
| histreedit     | If set, puts a failed history substitution back on the   |
|                | command line for re-editing.                             |
'----------------+----------------------------------------------------------'
| histverify     | If set, puts the command to be executed after a          |
|                | substitution on command line as if you had typed it.     |
'----------------'----------------------------------------------------------'

 shopt options can be set by a `shopt -s option' and
 can be unset by             a `shopt -u option'.

	Word Designators:
	(Word designators follow the event designators, separated by a collon ':')

	.--------------.------------------------------------------------------------.
	\| \| \|
	\| Designator \| Description \|
	\| \| \|
	'--------------+------------------------------------------------------------'
	\| 0 \| The zeroth (first) word in a line (usually command name). \|

	============ History Behavior Modification via Shell Variables ============

	.----------------.----------------------------------------------------------.
	\| \| \|
	\| Shell Variable \| Description \|
	\| \| \|
	'----------------+----------------------------------------------------------'
	\| HISTFILE \| Controls where the history file gets saved. \|

	\| HISTFILESIZE \| Controls how many history commands to keep in HISTFILE \|
	\| \| Default: 500 \|
	'----------------+----------------------------------------------------------'
	\| HISTSIZE \| Controls how many history commands to keep in the \|
	\| \| history list of current session. \|
	\| \| Default: 500 \|
	'----------------+----------------------------------------------------------'
	\| HISTIGNORE \| Controls which commands to ignore and not save to the \|
	\| \| history list. The variable takes a list of \|
	\| \| colon separated values. Pattern & matches the previous \|
	\| \| history command. \|
	'----------------'----------------------------------------------------------'

	============ History Behavior Modification via `shopt' Command ============

	.----------------.----------------------------------------------------------.
	\| \| \|
	\| shopt Option \| Description \|
	\| \| \|
	'----------------+----------------------------------------------------------'
	\| histappend \| Setting the variable appends current session history to \|
	\| \| HISTFILE. Unsetting overwrites the file each time. \|
	'----------------+----------------------------------------------------------'
	\| histreedit \| If set, puts a failed history substitution back on the \|
	\| \| command line for re-editing. \|
	'----------------+----------------------------------------------------------'
	\| histverify \| If set, puts the command to be executed after a \|
	\| \| substitution on command line as if you had typed it. \|
	'----------------'----------------------------------------------------------'

	shopt options can be set by a `shopt -s option' and
	can be unset by a `shopt -u option'.

	=============================== Examples ==================================

	$ echo a b c d e (executes `echo ab c d e`)
	a b c d e

	$ echo !!:3-$ (executes `echo c d e`)
	c d e

	$ echo !-2:*:q (executes `echo 'a b c d e'`)
	a b c d e

	$ echo !-3:1:2:4:x (executes `echo 'a' 'b' 'd'`)
	a b d

	$ echo !-4:1-3:s/a/foo/:s/b/bar/:s/c/baz/ (executes `echo foo bar baz`)
	foo bar baz

	$ tar -xzf package-x.y.z.tgz
	...
	$ cd !-1:$:r (executes `cd package-x.y.z`)
	package-x.y.z $

	$ ls -a /tmp
	file1 file2 file3 ...

	$ ^-a^-l^ (executes `ls -l /tmp`)
	-rw------- 1 user user file1
