since I switch between linux and macos a lot I wrote a dotfile function called "clip" that will work the same on both. nice thing is it will automatically paste if nothing is piped to it to copy so there's no need to use separate commands... although I just realized it might be nice to have a "passthrough" mode that both copies and pastes if you add this to a pipeline in order to capture some intermediate part to the clipboard

    if [[ "$(uname)" == "Darwin" ]]; then
      clip() {
        [ -t 0 ] && pbpaste || pbcopy
      }
    else # assume linux if not macos
      clip() {
        [ -t 0 ] && xclip -o -selection clipboard || xclip -selection clipboard
      }
    fi

At my job I have to work with a lot of JSON that's usually minimized. This command has single-handedly saved my sanity:

$ pbpaste | jq | pbcopy

Then I can paste it into whatever text editor I want and it's all nice & pretty-printed for me.

Bonus is that I don't have to change the command at all, just copy the minimized JSON to the clipboard (say from DBeaver, for example), then hit the 'up' arrow and enter.

I copied this functionality to linux it's been so useful.
