navi

An interactive cheatsheet tool for the command-line.

[!NOTE] Maintenance mode. navi still gets bug fixes, but no new features are planned. For a more modern alternative, check out ezlo.

navi allows you to browse through cheatsheets (that you may write yourself or download from maintainers) and execute commands. Suggested values for arguments are dynamically displayed in a list.

Pros

• it will spare you from knowing CLIs by heart
• it will spare you from copy-pasting output from intermediate commands
• it will make you type less
• it will teach you new one-liners

It uses fzf or skim under the hood and it can be either used as a command or as a shell widget (à la Ctrl-R).

Cheatsheet repositories

Running navi for the first time will help you download and manage cheatsheets. By default, they are stored at ~/.local/share/navi/cheats/.

You can also:

• browse through featured cheatsheets
• import cheatsheets from git repositories
• write your own cheatsheets (and share them, if you want)
• use cheatsheets from other tools, such as tldr and cheat.sh
• auto-update repositories
• auto-export cheatsheets from your TiddlyWiki notes using a TiddlyWiki plugin

Cheatsheet syntax

Cheatsheets are described in .cheat files that look like this:

% git, code

# Change branch
git checkout <branch>

$ branch: git branch | awk '{print $NF}'

The full syntax and examples can be found here.

Customization

You can:

• setup your own config file
• set custom paths for your config file and cheat sheets
• change colors
• resize columns
• change how search is performed
