zoxide - an alternative to z
I have for a long time maintained notes in a public wiki, finding the TIL ofJosh Branchaudjbranchaud/til was aneye-opener and I immiediately wanted to try it out, so after a few months I havefinally set it up.
I plan to migrate my earlier notes, so they are more easily accessible here asTIL snippets, this will be done when I have the time, one TIL at a time :-)
