histarc is an attempt to archive all my bash command history for later reference. It uses an sqlite database to record command history. histarc.bash defines a function histarc_update that provides an interface to the histarc program. In my bash interactive config files (.bashrc) I set it up like this,

# histarc support.
HISTARCBASH=${HOME}/projects/histarc/histarc.bash
if [ -f $HISTARCBASH ]
then
  source $HISTARCBASH
  PROMPT_COMMAND=histarc_update
fi

histarc uses a few files from my CTI project, clone that in an adjacent folder if you want to build histarc.
