Get pbcopy and pbpaste in Arch Linux

First you need the 'xsel' package.

pacman -S xsel

Then create aliases.

alias pbcopy='xsel --clipboard --input'
alias pbpaste='xsel --clipboard --output'

(Optional)

If you would like to make your aliases permanent, you need to add them to ~/.bashrc

For Bash:

nano ~/.bashrc

and paste

alias pbcopy='xsel --clipboard --input'
alias pbpaste='xsel --clipboard --output'

For ZSH:

nano .zshrc

and paste

alias pbcopy='xsel --clipboard --input'
alias pbpaste='xsel --clipboard --output'
