yes they do, you are probably just doing it wrong. it’s not very apparent in the way this image shows. bg and fg are used after hitting ctrl+z, for example.

Try this.

$ ping google.com
ctrl+z
$ fg (restarts ping google.com in the terminal)

$ bg (restarts ping google.com in the background)

If you “bg” a command, you will still see the output of the command, but you can input new commands. Try it.

Ooops, I didn’t mean to use that version for posting. Let me make up a new one using the correct version. I have the “joke” one on my desktop just for grins because I know what it really does.

To anyone using this version, remember that the rm -rf command does not make a computer faster, it removes files.

I rethought my Gimp fix for the typo; there is a link for the corrected image. Enjoy!

This is a cool background! I saw this after the image had been updated.

I fixed the typo with Gimp on my copy. Not too difficult to carefully cut the misspelled word, fill with black, and then insert a correctly spelled word. I still need to airbrush the new word slightly, but I like it better spelled right.

The rm ha-ha is exactly why I hate the Linux world, those neckbeards think it’s just so cute to pray on beginner knowledge levels forgetting that they too had to learn at one time.

Dave,

Yes typing things correctly is very important.

On that note, the original image contained a somewhat common joke in the Linux world regarding the ‘rm’ command that is not helpful to novice command line users. The claim was that it makes your computer faster and this is false, it removes files.

The image has been changed, it is a good idea to update to the newer image.

One thing I’ve read about this command-line stuff is how important it is to get things exactly right, because a command that’s mistyped can cause problems.

If that’s so, how concerned should we be about a cheat sheet which contains the word “direcotry” (as in “mkdir dir – create direcotry dir”)?

(Seriously, the wallpaper’s a great idea, and clearly that particular typo is within a description not an actual command – but are there any other possible problems in there for the unwary?)
