.SH NAME
|
|
\fBhh\fR \- shell history suggest box
|
|
.SH SYNOPSIS
|
|
.B hh [option] [arg1] [arg2]...
|
|
.SH DESCRIPTION
|
|
.B hh
|
|
uses shell history to provide suggest box like functionality
|
|
for commands used in the past. By default it parses .bash-history
|
|
file that is filtered as you type a command substring. Commands
|
|
are not just filtered, but also ordered by a ranking algorithm
|
|
that considers number of occurences, length and timestamp. In addition
|
|
hh allows removal of commands from history - for instance with a typo or with a sensitive content.
|

.SH INSTALLATION
|
|
Add the following lines to ~/.bashrc:
|
|
.nf
|
|
.sp
|
|
shopt -s histappend
|
|
export PROMPT_COMMAND="history \-a; history \-n; ${PROMPT_COMMAND}"
|
|
bind '"\eC\-r": "\eC\-ahh \eC-j"'
|
|
.sp
|
|
.fi
|
|
The first command ensures that new history items are appended to .bash_history
|
|
(instead of overwriting). The second command ensures synchronization of the
|
|
history between memory and file system. The third command binds hh to
|
|
Ctrl-r shortcut.
