Two points:

1: It’s nothing more than an inconvenience to highlight the text, then copy-paste using keyboard shortcuts (I’m not going to tell you how to do them, you should know them already if you want to start messing with the Terminal)

2: It’s also nothing more than an inconvenience to manually type the command into the Terminal yourself using that nifty little thing attached to your machine that I call a keyboard.

Finally, this is a post that offers helpful tips to people who might be able to make use of them. Insulting said helpful poster shows a sense of entitlement that reeks of spoiled brat… Something I will always detest.

What kind of ungrateful, selfish person rips into someone who is only trying to help others?

You’re a goddamn idiot. If you’re not even able to select & copy you have no business opening the terminal.

no it is not, only the spaces and the fourfinger-up thing. 😉

That’s the windows way, and look where it got them. Millions of grannies everywhere breaking stuff they don’t understand.
