If you’re an Arch Linux user, you’ll find yourself typing “pacman -Sy <package>” or “powerpill -Syu” a lot. Here are some useful shell aliases (here, they are for Zsh) that I use to make things much, much easier:
alias p='sudo pacman' alias pu='sudo pacman -Syu' alias pa='sudo pacman -Sy' alias pq='sudo pacman -Q' alias pp='sudo powerpill' alias ppu='sudo powerpill -Syu' alias ppa='sudo powerpill -Sy'
And then all I have to type is ppu, and my system is upgraded. Also, I have in my /etc/sudoers file the following:
shinobu exelion=NOPASSWD: /usr/bin/pacman shinobu exelion=NOPASSWD: /usr/bin/powerpill
This way, I don’t have to type my password every time I want to use pacman/powerpill.
