Share a script/alias you use a lot

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)"
}
