tldr is great. Basically a crowd-sourced alternative to man with much more concise entries. Example:

$ tldr dhcpcd

  DHCP client.
  More information: <https://roy.marples.name/projects/dhcpcd>.

  Release all address leases:

      sudo dhcpcd --release

  Request the DHCP server for new leases:

      sudo dhcpcd --rebind

As primarily a Windows admin (Yes, we exist on Lemmy ;) ) here are few I use often.

• Enter-PSSesion
• Get-ADUser (also group and computer)
• CLS (aka the superior clear)
• ii . (short for Invoke-Item . which runs the selected object using the default method. For paths (like .) the default is explorer, so ii . opens the current directory using explorer.)
• ft (short for Format-Table formats piped input as a table.)
• fl (short for format-like. Used like ft but for lists.)
• Where-Object
• Select-Object

ls and cd

I use atuin (link) all the time

xdg-open FILE - opens a file with the default GUI app. I use it for example to open PDFs and PNG. I have a one letter alias for that. It can also open a file explorer in the current directory xdg-open . . Should work on any compliant desktop environment (gnome/kde).

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.

exit

diff -y -W 200 file1 file2

Shows a side by side diff of 2 files with enough column width to see most of what I need usually.

I have actually aliased this command as diffy

ctrl-r

searching bash history

du -sh * | sort -h

shows size of all files and dirs in the current dir and sorts them in ascending order so you can easily see the largest files or dirt ant the end of the list

ls -ltr

Shows the most recently modified files at the end of the listing.

I’ve recently started using tmux when starting a new SSH session to try to build the habit.

g-push which is alias for

git push origin `git branch --show`

Which I’m writing on my phone without testing or looking

For Debian based/descended distros:

sudo apt-get update && sudo apt-get upgrade

And technically I also regularly use

redshift -O 3000

all of the blue light filter programs try to align themselves with a user’s geographic location and time, but I don’t keep normal hours

sudo

Zoxide, dust, fd, rg, btm, tokei. So many newer Rust tools that are way better than the old stuff.

I do love fuck.
