Cheat sheets for the shell

DIY

If you are missing an important command, you can create your own cheat sheet for the command and call it in navi. Use a file from /opt/navi/cheats/ as a template (for a detailed explanation of the syntax, see GitHub [6]). Then call the new cheat sheet with a command like the one shown in line 1 of Listing 3 or include several directories in $NAVI_PATH, separated by colons (line 2).

Listing 3

Calling a new cheat sheet

01 $ navi --path "/<MyOwn>/<Cheatsheets>"
02 $ export NAVI_PATH="/<MyOwn>/<Cheatsheets>:/<Even>/<more>/<Cheatsheets>"

Conclusions

While the built-in cheat sheets for Docker, Kubernetes, and Git focus strongly on developers' needs, they also contain many cheat sheets useful for desktop users. In particular, navi makes it easier for console gamers to handle complex command-line commands.

In addition, navi can be extended by integrating online or DIY cheat sheets. However, navi's developer recommends using the --print option to check commands from online cheat sheets.

Finally, Katacoda [7] lets you test navi prior to installation to see if it's a good fit for your needs. If it isn't, you will find other similar tools on GitHub, such as cheat, cmdmenu, BEAVR, and howdoi.
