This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.
| Description | Syntax |

| Get a single character | ${VARNAME[index]} |
systemctl list-unit-filessystemctl list-unitssystemctl --failedsystemctl --allsystemctl start [SERVICE_NAME]systemctl stop [SERVICE_NAME]

Any GitHub wiki can be cloned by appending wiki.git to the repo url, so the clone url for
the repo https://myorg/myrepo/ is: git@github.com:myorg/myrepo.wiki.git (for ssh) or https://github.com/my/myrepo.wiki.git (for https).
You make edits, and commit and push your changes, like any normal repo. This wiki repo
is distinct from any clone of the project repo (the repo without wiki.get appended).
