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)"
}

It's not terribly exciting but I find myself using this a lot:

#!/bin/sh

echo "$*" | sed -e "s/x/*/g" | bc -l

Just a little shorthand for bc that allows me to write "x" instead of "*" to avoid shell expansion nonsense. I put it in ~/.local/bin/= so I can e.g. just write = 17+4x5. Combined with a Quake-style terminal this is much faster than launching a calculator app. It's a script instead of an alias so it works regardless of the shell I'm currently using.

The call to bc -l could be replaced with one to qalc -t if you know qalc to be present on the system .
