tldr
is great. Basically a crowd-sourced alternative toman
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
Well…slap my ass and call me Mary…
Thanks kind internet stranger!:O
Woah, that’s dope as heck. Thank you!

maybe I’ll throw als -a
Nah you gotta alias ls -a to la for more efficiency.
l
I use -A instead, which doesn’t show “.” and “…”
Don’t forget your

thrown in to get back your bearings!Done be silly, that’s part of my prompt.
As primarily a Windows admin (Yes, we exist on Lemmy ;) ) here are few I use often.

I went a little overboard and wrote a one-liner to accurately answer this question
history|cut -d " " -f 5|sort|uniq -c|sort -nr|head -5
Note:
history
displays like this for me20622 2023-02-18 16:41:23 ls
I don’t know if that’s because I setHISTTIMEFORMAT='%F %T '
in .bashrc, or if it’s like that for everyone. If it’s different for you change-f 5
to target the command. Use-f 5-7
to include flags and arguments.My top 5 (since last install)
2002 ls 1296 cd 455 hx 427 g 316 find
g
is an alias for gitui. When I include flags and arguments most of the top commands are aliases, often shortcuts to a project directory.Not to ramble, but after doing this I figured I should alias the longest, most-used commands (even aliasing
ls
tol
could have saved 2002 keystrokes :P) So I wrote another one-liner to check for available single characters to alias with:for c in a b c d e f g h i j k l m n o p q r s t u v w x y z; do [[ ! $(command -v $c) ]] && echo $c; done
In .bash_aliases I’ve added
alias b='hx ${HOME}/.bash_aliases'
to quickly edit aliases andalias r='source ${HOME}/.bashrc'
to reload them.Helix?
Yup! Migrated from VSCodium; wanted to learn a modal editor but didn’t have the time or confidence to configure vim or neovim. It’s been my go-to editor for 2+ years now.
I’ve been using vi (just the basics) for ~4 years, I don’t think I could be arsed to pick up the keybindings the other way around lol. I’ve heard very good things about Helix, of course
As another longtime Vi user - I had a hell of a time & wound up switching back lol
I think for a lot of folks Helix would be intuitive. Vi has her hooks in me, though.
Holy shit, you’re a madman

clear
because apparently I am too scatterbrained to comprehend more than one full page of text in the terminalI like using CRTL+L to clear. It’s nice because you can have a command typed out and still be able to press CTRL+L to clear the screen and keep the command typed out.
Uhhh…
sudo su

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 directoryxdg-open .

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.
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
Chuck the -y in there for extra lazy mode
I would but much like somebody else’s recent post I have in the past nuked my install by blindly agreeing to some recommended software removals before. These days I like to double check what packages are being updated and replaced.
topgrade
does this and and a lot more
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.
I’ve recently started using
tmux

exec $SHELL -l
omz reload
not going to say zsh is better than bash or fish, but oh-my-zsh does make it more attractive for some use-cases
omz is bloat and slows fown your shell a lot. Just do this: https://www.youtube.com/watch?v=21_WkzBErQk
And I’d recommend starship for a custom prompt, it’s really good: https://starship.rs
Edit: For other ZSH nice-to-haves: https://www.youtube.com/watch?v=eLEo4OQ-cuQ
I’ll have to give starship a try, seems like a cool way to handle customizing the prompt
as to the “omz is bloat and slows down your shell”:
- How slow? Because I’ve never noticed. Are we talking about waiting for 15 seconds when I should only have to wait for 1, or are we talking theory and the difference between 0.5 vs 0.08 seconds in benchmarks?
Because I’ve never been inconvenienced by the speed of my shell nor terminal emulator, despite having tried all kinds of setups. Turns out that “blazing fast” gpu accelerated terminal really didn’t make much of a difference on human timescales. Now I’m at the point where I appreciate the features over the performance.
- In reply to Brody’s point, I’m inclined to say “yes, and…?”
OMZ automates a lot. Sure, I could follow his way of manulaly sourcing dozens of individual shellscripts and making my own aliases and have a zshrc 1200 lines long… Or I could just let omz handle it.
Yes it’s mostly just a plugin manager, and…? Yes it automates a process I could do manually, and… ? Yes, it uses bindings that I didn’t personally write, and… ?
Fuck off with the clickbait “You’re living your life wrong, do this lifehack instead!!!” (and the lifehack is to reinvent the wheel) bullshit
Here’s a fun real lifehack: try things out for yourself, don’t just listen to and parrot other people’s opinions, don’t be afraid to go against the grain. Way more fun and fulfilling that way!
How slow, because I neved noticed
Trust me, it’s noticeable. Or at least it was for me. Numbers wise, it doesn’t sound like much, but the difference between 0.05s and 0.5s (which are roughly the times I was experiencing) is very noticeable, at least for me. One is done before you’ve even fully lifted the finger off the key, while with the other you’re preparing to press (or maybe you’re already pressing pressing) the next key, by the time you see a reaction.
Your mileage may vary.
