Automatically index your shell history in a full-text search database. Magic!

• Uses SQLite3's excellent FTS4 extension to provide full-text search.
• Respects HISTTIMEFORMAT if set.

• Bash

Download the latest release and extract it somewhere on your $PATH.

Alternatively, install Duiker from source. To build the package you will need:

• jq
• Rust 1.17+ (install with rustup)

Simply run:

make install

Import your existing shell history:

HISTTIMEFORMAT='%s ' history | duiker import -

If you want to automatically import your shell history on-the-fly, you can add duiker import to your PROMPT_COMMAND¹.

Run duiker magic to print a shell snippet that automatically imports your last command into Duiker:

duiker magic

Configure this shell snippet as part of your PROMPT_COMMAND. Run duiker magic --help for an example.

Duiker indexes your shell history in an SQLite3 full-text search table.

You can use any MATCH² expression to search the database:

$ duiker search git
2017-04-13 15:50:02     git staged
2017-04-13 15:50:14     git commit -a
2017-04-13 15:55:07     git diff

$ duiker search '(git OR fossil) diff'
2017-04-27 15:15:01     git diff
2017-04-27 15:15:49     git diff
2017-04-28 14:49:19     fossil diff
2017-04-28 14:53:09     fossil diff src/main.rs

$ duiker search 'sqlite*'
2017-03-04 19:00:42     sqlite3 db.sqlite
2017-03-04 19:13:11     rm db.sqlite

Duiker only supports Bash at present. Pull requests for other shells welcome.
