Getting cheatsheets via curl cheat.sh/INSERT_COMMAND_HERE

No install necessary, Also, you can quickly search within the cheatsheets via ~. For example if you copy curl cheat.sh/ls~find will show all the examples of ls that use find. If you remove ~find, then it shows all examples of ls.

I have a function in my bash alias for it (also piped into more for readability):

function cht() { curl cheat.sh/"$1"?style=igor|more }

qmv -f do ${dir}

... for quickly moving and renaming files. The default 'qmv' opens up your preferred text editor with a list of the source and destination name of the directory of files you want to move/rename. The '-f do' tells the command we only want to see/edit the [d]estination [o]nly. If you need to rename/move a bunch of files, it's much quicker to do it in vim (at least for me).

du -sh /too/bar to get size of files/folders. sudo !! inserts sudo into previous command when forgotten. yay for full system update if yay is installed. cat reads files.

Going to shamelessly plug my custom bashrc setup which has a ton of little scripting helpers and a few useful aliases. Remember to clone recursively if you want to try it out. (Still very much a work in progress, but it's getting to be pretty robust)

I really like how nushell can parse output into it's native structures called tables using the detect command.

Unlike string outputs, tables allow for easy data manipulation through pipes like select foo will select foo key and you can filter and even reshape the datasets.

This is great if you need to work with large data pipes like kuberneters so you can do something like:

kubectl get pods --all-namespaces | detect columns | where $it.STATUS !~ "Running|Completed" | par-each { |it| kubectl -n $it.NAMESPACE delete pod $it.NAME }

This looks complex but it parses kubectl table string to table object -> filters rows only where status is not running or completed -> executes pod delete task for each row in parallel.

Nushell take a while to learn but having real data objects in your terminal pipes is incredible! Especially with the detect command.

There's are few more shells that do that though nu is the most mature one I've seen so far.

locate, from the mlocate package. So useful. Honorable mention goes out to tldr.
