I am not a GNU/Linux master, nor a terminal expert, i was going to make a bash script to clean orphan packages, then i read this...

Using arrays or loops in shells is often signs of bad coding practice.

• Source: store the command output in an array and print one by one.

... So i decided to research about awk, and i did this one-line command to clean your orphan pacman packages sudo pacman -R $(pacman -Qdt | awk '{print $1}')

• pacman -Qdt: Used to display the orphan packages.
• awk '{print $1}': Prints the first field of the output.
