Cicada History

Shell history items are stored with sqlite database. You can find the file location with cinfo command. Like bash, you can use Ctrl-R, Ctrl-P, Ctrl-N, Arrow-UP, Arrow-DOWN keys to access history.

Recommend that in your ~/.inputrc, you have:

"\e[1;9D": backward-word
"\e[1;9C": forward-word
"\e[A": history-search-backward
"\e[B": history-search-forward

With above inputrc setup, you can type a part (prefix) of history, and then hit <Arrow-Up> to retrive items start with this prefix:

$ echo 1.23
$ echo foo bar
$ echo 1<Arrow-UP>  # will get you `echo 1.23`

Prefixing spaces will suppress history to be saved

You can prevent commands from saving into history by prefixing spaces with them.

$ echo foo bar
$ echo 123
$  echo secret 235
  ^ prefix command with a space to make command skip saving to history.
$ history
2: echo 123
1: echo foo bar

History Environment Variables

There are several environment variables on history.

export HISTORY_FILE="$HOME/.local/share/cicada/history.sqlite"
export HISTORY_SIZE=99999
export HISTORY_TABLE="cicada_history"

You can modify the settings of history related value in RC-file.

History is Immutable
