alias forgethist=unset HISTFILE

Useful when I run the same two commands 20 times in a row

in zsh you can just forbid it to save duplicates

macallik OP ,

Digging the systemctl ones. I added myself to the group so that I wouldn't have to write sudo each time, but I might as well alias the entire prompt for restart and status to make it even shorter

These are some pacman+fzf implementations from the arch wiki + a flatpak implementation i did with fzf(still needs some polish but it works).

alias pacq=$‘pacman -Q | fzf’

alias pacs=$‘pacman -Slq | fzf --multi --preview 'pacman -Si {1}' | xargs -ro sudo pacman -S’

alias pacr=$‘pacman -Qq | fzf --multi --preview 'pacman -Si {1}' | xargs -ro sudo pacman -Rns’

alias flatr=$‘flatpak list | fzf --preview 'flatpak info {2} ' | grep -Eo '[a-ZA-Z]+.[^ ]+' |awk '{print $1}' | xargs -ro flatpak remove --delete-data’

macallik OP ,

Good to see another exa user. Care to break down what yay does btw?

megane_kun , (edited )

Ah, yay is an AUR helper, though I personally see it as a pacman helper as well. Link here. Some of the flags and options that can be used for pacman can be used for yay, thus, some of the flags in the aliases I use are actually for pacman. Anyways, on to the breakdown.

alias yy=‘yay -Y --needed --norebuild --nocleanafter --nodiffmenu --noredownload --nocleanmenu --removemake --sudoloop’

This one is what I use to look up for packages. The result of runnning yy «search term» would be a list of packages matching the search term and prompting the user on which package(s) to install.

flag description
-Y performs yay-specific operations.
–needed (pacman) do not reinstall up to date packages
–norebuild skips package build if in cache and up to date
–nocleanafter do not remove package sources after successful build
–noredownlod skip pkgbuild download if in cache and up to date
–nodiffmenu don’t show diffs for build files
–nocleanmenu don’t clean build PKGBUILDS
–removemake remove makedepends after install
–sudoloop loop sudo calls in the background to avoid timeout

alias ya=‘yay -S --needed --norebuild --nocleanafter --nodiffmenu --noredownload --nocleanmenu --removemake --sudoloop’

This one is what I use for installing packages. Useful if I already know what package I would be installing.

flag description
-S (pacman, extended by Yay to cover AUR as well) Synchronize packages. Packages are installed directly from the remote repositories, including all dependencies required to run the packages.

alias yu=‘yay -R --recursive --nosave’

This one is what I use when uninstalling packages. I usually check the package name with something like yay -Qi «package-name-guess» beforehand.

flag description
-R (pacman, extended by Yay to also remove cached data about devel packages) Remove package(s) from the system.
–recursive (pacman) Remove each target specified including all of their dependencies, provided that (A) they are not required by other packages; and (B) they were not explicitly installed by the user. This operation is recurisve and analogous to a backwards –sync operation.
–nosave (pacman) Instructs pacman to ignore file backup designations. (This avoids the removed files being renamed with a .pacsave extension.)

I actually don’t know much about both yay and pacman myself, since the aliases were just passed onto me by the same friend who helped me (re-)install my system (long story) and set-up the aliases. Having looked all these up, however, I might make a few changes (like changing the –nocleanafter and –nocleanmenu options to their clean ones`).

soloner ,

I like the idea of binding numbers to parent directory traversal. I do cd …/… a lot in one of my projects (switching between source code and terraform folder), it’d be handy to get out of the terraform folder by just typing 2.

megane_kun ,

I actually would do cd … and then do a pwd (and so on, repeatedly) because I often get confused and have a very short attention span that the aliases ended up unused.

olafurp ,

I have codebase of 5k lines. Most used are git commands (squash all to merge base, push to current branch, commit with format etc), work shortcuts for starting projects, time logging, startup programs. Then I have some cli interface for redo commands, size of current folders for disk pruning, abandoned project alias, os commands like brightness adjust, launch game on steam with qwert instead of dvorak keyboard, search cli history, kill with regex matching…

Just anything that I don’t want to Google twice. bash is life

iHUNTcriminals ,

What… I didn’t know this was a thing.

So I could make be “sudo gimme-dat-new-new” Instead of “sudo DNF upgrade -y”

Vilian ,

you can just put “gimme-dat-new-new”

s20 ,

alias gimmie-dat-new-new=‘sudo dnf upgrade -y’

Although you should probably look over your upgrade before applying it as a general good practice. But, hey, I do this myself (dnfup instead of gimmie-dat-etc.), so I can’t talk too much shit.

ETA: If you want it to be a persistent alias, though, you gotta add it to your .bashrc

I'm going to assume all these syntax highlighted HTML embeds are from Lemmy users. Sadly, illegible on Kbin.

Ahhh I was wondering what that was as a fellow kbin-er. I was pleasantly surprised when I found out I could create threads across the fediverse today as a consolation.

This is a separate reply since I didn’t know that you can include shell functions here.

I made this little function read_latest_log() because I just want to “read the latest log file” in a directory full of timestamped log files. I made a helper function separator_line_with_text() to help with the output, basically setting off the file-info portion (just the filename for now) from the file contents.

Sorry for all the edits, for some reason anything that looks like an HTML tag gets erased.
