From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

A while ago I made a tiny function in my ~/.zshrc to download a video from the link in my clipboard. I use this nearly every day to share videos with people without forcing them to watch it on whatever site I found it. What's a script/alias that you use a lot?

# Download clipboard to tmp with yt-dlp
tmpv() {
  cd /tmp/ && yt-dlp "$(wl-paste)"
}

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.

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

Note: This is macOS-specific, as written, but as long as your terminal supports images, you should be able to adapt it just fine.

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.

Here are probably the most useful ones. I prefer for rm to be interactive so I don't accidentally delete something important and for mkdir to create a parent directory if necessary.

alias rm='rm -i'
alias mkdir='mkdir -p'
alias podup='podman-compose down && podman-compose pull && podman-compose up -d'

This extract function (which I didn't make myself, I got it from when I was using nakeDeb) has been pretty useful too.

function extract()
{
     if [ -f $1 ] ; then
         case $1 in
             *.tar.bz2)   tar xvjf $1     ;;
             *.tar.gz)    tar xvzf $1     ;;
             *.bz2)       bunzip2 $1      ;;
             *.rar)       unrar x $1      ;;
             *.gz)        gunzip $1       ;;
             *.tar)       tar xvf $1      ;;
             *.tbz2)      tar xvjf $1     ;;
             *.tgz)       tar xvzf $1     ;;
             *.zip)       unzip $1        ;;
             *.Z)         uncompress $1   ;;
             *.7z)        7z x $1         ;;
             *.xz)        unxz $1         ;;
             *)           echo "'$1' cannot be extracted via >extract<" ;;
         esac
     else
         echo "'$1' is not a valid file"
     fi

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.

[–] mmmm@sopuli.xyz 10 points 1 week ago* (last edited 1 week ago)

I use a KDE variant of this that uses klipper instead (whatever you pipe to this will be available in klipper):

` #!/bin/sh

function copy {
    if ! tty -s && stdin=$(</dev/stdin) && [[ "$stdin" ]]; then
        stdin=$stdin$(cat)
        qdbus6 org.kde.klipper /klipper setClipboardContents "$stdin"
        exit
    fi

    qdbus6 org.kde.klipper /klipper getClipboardContents
}

copy $@`

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'

I also have various small scripts and functions:

  • a for package management (think apt but has simplified arguments which makes it faster to use in usual cases),
  • e for opening file in Emacs,
  • g for git,
  • s for sudo.

And here’s ,:

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

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

This tmux wrapper is remarkably convenient:

Usage:

# Usage: t [session-name]
#
# With no arguments:
#   Lists existing tmux sessions, or prints "[No sessions]" if none exist.
#
# With a session name:
#   Attempts to attach to the named tmux session.
#   If the session does not exist, creates a new session with that name.
#
# Examples:
#   t            # Lists all tmux sessions
#   t dev        # Attaches to "dev" session or creates it if it doesn't exist

function t {
	if [[ -z $1 ]]; then
		tmux ls 2> /dev/null || echo "[No sessions]"
	else
		tmux attach -t $@ 2> /dev/null
		if [[ $? -ne 0 ]]; then
			tmux new -s $@
		fi
	fi
}

I have a few interesting ones.

Download a video:

alias yt="yt-dlp -o '%(title)s-%(id)s.%(ext)s' "

Execute the previous command as root:

alias please='sudo $(fc -n -l -1)'

Delete all the Docker things. I do this surprisingly often:

alias docker-nuke="docker system prune --all --volumes --force"

This is a handy one for detecting a hard link

function is-hardlink {
  count=$(stat -c %h -- "${1}")
  if [ "${count}" -gt 1 ]; then
    echo "Yes.  There are ${count} links to this file."
  else
    echo "Nope.  This file is unique."
  fi
}

I run this one pretty much every day. Regardless of the distro I'm using, it Updates All The Things:

function up {
  if [[ $(command -v yay) ]]; then
    yay -Syu --noconfirm
    yay -Yc --noconfirm
  elif [[ $(command -v apt) ]]; then
    sudo apt update
    sudo apt upgrade -y
    sudo apt autoremove -y
  fi
  flatpak update --assumeyes
  flatpak remove --unused --assumeyes
}

I maintain an aliases file in GitLab with all the stuff I have in my environment if anyone is curious.

[–] golden_zealot@lemmy.ml 11 points 1 week ago (1 children)

Execute the previous command as root

Fun fact if you are using bash, !! will evaluate to the previous command, so if you miss sudo on some long command, you can also just do sudo !!.

[–] IronKrill@lemmy.ca 5 points 1 week ago

on most of my systems I get tired of constantly lsing after a cd so I combine them:

cd(){
    cd $1 && ls
}

(excuse if this doesn't work, I am writing this from memory)

I also wrote a function to access docker commands quicker on my Truenas system. If passed nothing, it enters the docker jailmaker system, else it passes the command to docker running inside the system.

docker () {
        if [[ "$1" == "" ]]; then
                jlmkr shell docker
                return
        else
                sudo systemd-run --pipe --machine docker docker "$@"
                return
        fi
}

I have a few similar shortcuts for programs inside jailmaker and long directories that I got sick of typing out.

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

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.

[–] randy@lemmy.ca 11 points 1 week ago

I used to have scripts like that, but eventually switched to ssh aliases. You can set up an alias for each machine in ~/.ssh/config with lines like this:

Host p1
    HostName 192.168.1.123
    Port 22
    User pi

Then access with ssh p1. Slightly more typing, but avoids adding more commands to your $PATH. Also has the benefit of letting you use the same alias with other ssh-related commands like sftp.
