.TH HH 1
.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.

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.
