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

<Esc>[2J<Esc>[H

Is one of my favorites. Of course, most of you are too young to know what that means.

I often play an old DOS game in DOSBox, and when I exit it doesn’t reset the screen resolution. So I reset it manually by typing

xrandr -output e-DP1 -auto

$ z

A great cd alternative

Also $ sudo paru -Syu

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

g-push which is alias for

git push origin `git branch --show`

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

In my ~/.bashprofile: alias resource="source ~/.bashprofile"

In my terminal: resource

Anything to save a few characters

ls and cd

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.

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 do love fuck.

I use “ping” every time I suspect my internet might be going a bit slow.

cd then ls then cd then ls maybe I’ll throw a ls -a

More of a shortcut, CTRL + A + D to exit the current session (exits a sudo su first, then a ssh, then the actual terminal)
