Ask HN: What are your favourite bash aliases?

Wondering what people use day-to-day?

I currently have:

  alias dev="cd ~/Documents/dev"
  alias bashreload="source ~/.bashrc && echo Bash config reloaded"
  alias sleep="pmset sleep now"
  weather() { curl wttr.in/"$1"; }
  alias lenny='echo \_(ツ)_/¯ | pbcopy'
