I usually set up an alias or script to update everything on my system. For example, on Ubuntu, I would do this: alias sysup='snap refresh && apt update && apt upgrade'

And on Arch, I do this: alias sysup ='flatpak update && paru'

Funny enough you'd need to use sudo to run this on Ubuntu, but not in the Arch example because paru being neat

For doing stuff in a directory, I use a replacement for cd
command.

For aliases:

alias +='git add'
alias +p='git add -p'
alias +u='git add -u'
alias -- -='cd -'
alias @='for i in'
alias c='cargo'
alias date='LANG=C date'
alias diff='cdiff'
alias gg='git grep -n'
alias grep='grep --color=auto'
alias ll='ls -o'
alias ls='ls -vFT0 --si --color=auto --time-style=long-iso'
alias rmd='rmdir'

And here’s ,:

$ cat ~/.local/bin/,
\#!/bin/sh

if [ $# -eq 0 ]; then
    paste -sd,
else
    printf '%s\n' "$@" | paste -sd,
fi

Similar to yours OP I copy many URLs and then run my script that takes the number of URLs I copied eg 5,and downloads them with yt-dlp and GNU parallel to ~/Videos

I use CopyQ to hold the clipboard history.

alias dockpull="docker compose pull"
alias dockup="docker compose up -d --remove-orphans"

alias chx='chmod +x'
alias rr='rm -rf'
alias shrug="echo '¯\_(ツ)_/¯'"

To answer your question realistically I did history | sed "s/.* //" | sort | uniq -c | sort -n

which returned as first non standard command lr which from my grep lr ~/.bashrc is alias lr="ls -lrth"

I replaced rm with trash-put, just in case I realize I need some files that I removed down the line.

alias rm='trash-put'

Also I like to alias xclip:

alias clippy='xclip -selection clipboard'

# cat things.txt | clippy

I often want to know the status code of a curl request, but I don't want that extra information to mess with the response body that it prints to stdout.

What to do?

Render an image instead, of course!

curlcat takes the same params as curl, but it uses iTerm2's imgcat tool to draw an "HTTP Cat" of the status code.

It even sends the image to stderr instead of stdout, so you can still pipe curlcat to jq or something.

\#!/usr/bin/env zsh

stdoutfile=$( mktemp )
curl -sw "\n%{http_code}" $@ > $stdoutfile
exitcode=$?

if [[ $exitcode == 0 ]]; then
  statuscode=$( cat $stdoutfile | tail -1 )

  if [[ ! -f $HOME/.httpcat$statuscode ]]; then
    curl -so $HOME/.httpcat$statuscode https://http.cat/$statuscode
  fi

  imgcat $HOME/.httpcat$statuscode 1>&2
fi

cat $stdoutfile | ghead -n -1

exit $exitcode

Because using docker can sometimes cause ownership issues if not properly configured in your docker-compose.yml, I just added an alias to ~/.zshrc to rectify that.

I have a bunch of the server aliases. I use those and gl the most.

alias clip='xclip -selection clipboard'

When you pipe to this, for example ls | clip, it will stick the output of the command ran into the clipboard without needing to manually copy the output.

I used this a lot when I had to deal with CSV files — it simply shows the data in a nice format. It's an alias for the fish shell by the way.

# Changes to top-level directory of git repository.

Hey OP, consider using $XDG_RUNTIME_DIR instead of /tmp. It's now the more proper place for these kinds of things to avoid permission issues, although I'm sure you're on a single user system like most people. I have clipboard actions set to download with yt-dlp 😀

My favorite aliases are:

alias dff='findmnt -D -t nosquashfs,notmpfs,nodevtmpfs,nofuse.portal,nocifs,nofuse.kio-fuse'

alias lt='ls -t | less'

I use Clevis to auto-unlock my encrypted root partition with my TPM; this means when my boot partition is updated (E.G a kernel update), I have to update the PCR register values in my TPM. I do it with my little script /usr/bin/update_pcr:

\#!/bin/bash
clevis luks regen -d /dev/nvme1n1p3 -s 1 tpm2

Now, if I were really fancy and could get it to correctly update the TPM binding immediately after the update, I would have something like an apt package shim with a hook that does it seamlessly. Honestly, I'm surprised that distributions haven't developed robust support for this; the technology is clearly available (I'm using it), but no one seems to have made a user-friendly way for the common user to have TPM encryption in the installer.

Not exactly a single script, but I use scm breeze for git stuff. Has a ton of QoL features for working with git

I wrote a script called please. You input please followed by any other command (e.g. please git clone, please wget blahblah) and a robotic voice will say "affirmative," then the command will run, and when it completes, the robotic voice reads out the exit code (e.g. "completed successfully" or "failed with status 1" etc.)

This is useful for when you have a command that takes a long time and you want to be alerted when it's finished. And it's a gentleman.

I have a collection of about 8 machines around the house (a lot of Raspberry Pi) that I ssh around to from various points.

I have setup scripts named: ssp1 ssp2 ssba ss2p etc. to ssh into the various machines, and of course shared public ssh keys among them to skip the password prompt. So, yes, once you are "in" one machine in my network, if you know this, you are "in" all of them, but... it's bloody convenient.

# fish shell
function jmpd
    set _selection $(fzf --walker=dir);
    if test -n "$_selection"
        cd "$_selection";
    end
end

git push origin `git branch --show`

Technically not an alias, because I just use nushell's history + autocompletion everytime I use it, but one could alias it. I think I might even write a custom command for it, with path argument, some day. Anyway, here it goes:

rsync -aPh -e "ssh -p 2222" test@172.16.0.86:/storage/emulated/0/PicturesArchive/ ~/PicturesArchive/

I run an ssh daemon on my phone, and use this snippet to back up my photos.
