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

Chuck the -y in there for extra lazy mode

[โ€“] NauticalNoodle@lemmy.ml 1 points 2 minutes ago

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.

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

In my terminal: resource

Anything to save a few characters

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

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 do love fuck.

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

[โ€“] BaumGeist@lemmy.ml 1 points 9 minutes ago* (last edited 8 minutes ago)

does it do all of those with one press? Id that what the 'A' is for?

[โ€“] lluki@feddit.org 10 points 10 hours ago

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

cd then ls then cd then ls maybe Iโ€™ll throw a ls -a

[โ€“] vrighter@discuss.tchncs.de 7 points 11 hours ago

I use -A instead, which doesn't show "." and ".."

clear because apparently I am too scatterbrained to comprehend more than one full page of text in the terminal

[โ€“] feddylemmy@lemmy.world 1 points 41 minutes ago

I 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.

[โ€“] mexicancartel@lemmy.dbzer0.com 3 points 12 hours ago (1 children)

I almost never use clear because i'm afraid if i will need the text later.(just like infinity tab number on firefox)

Oh god I also do this... See the comment below, I ran history|cut -d " " -f 5|sort|uniq -c|sort -nr|less on my personal laptop, my third most commonly used command (behind ls and cd) is just typing in nothing...

[โ€“] electric_nan@lemmy.ml 3 points 11 hours ago

Saving this thread for later, but I use rsync -a a lot.

[โ€“] pemptago@lemmy.ml 26 points 18 hours ago (5 children)

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 me 20622 2023-02-18 16:41:23 ls I don't know if that's because I set HISTTIMEFORMAT='%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 to l 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 and alias r='source ${HOME}/.bashrc' to reload them.

Uhhh...sudo su

Don't be like me

[โ€“] LaSirena@lemmy.world 30 points 19 hours ago (1 children)

tldr because I am too impatient to read through man pages or google the exact syntax for what I want to do.

[โ€“] pixelscript@lemm.ee 19 points 18 hours ago (5 children)

There are exactly three kinds of manpages:

  1. Way too detailed
  2. Not nearly detailed enough
  3. There is no manpage

I will take 1 any day over 2 or 3. Sometimes I even need 1, so I'm grateful for them.

But holy goddamn is it awful when I just want to use a command for aguably its most common use case and the flag or option for that is lost in a crowd of 30 other switches or buried under some modal subcommand. grep helps if you already know the switch, which isn't always.

You could argue commands like this don't have "arguably most common usecases", so manpages should be completely neutral on singling out examples. But I think the existence of tl;dr is the counterargument.

Tangent complaint: I thought the Unix philosophy was "do one thing, and do it well"? Why then do so many of these shell commands have a billion options? Mostly /s but sometimes it's flustering.

Sudo !!

It reruns the last command as sudo.

Pretty useful since I'm always forgetting.

let me guess, you either use arch or gentoo

[โ€“] pyr0ball@sh.itjust.works 3 points 14 hours ago* (last edited 14 hours ago)

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)
