There are two ways to clear a screen. You could type in 'clear' then press enter or press the command key cmd + letter 'L' on the keyboard; if using the mac. I guess on windows you can replace command key with control key on the keyboard.

On windows, in the Interactive Ruby command terminal, the only command that has worked for me is

system('cls')

for example, type:

irb(main):091:0> system('cls')

Ctrl + L does not seem to work.

This actually requires two steps if you're in irb.

If you're using workspaces on a Mac, type 'exit' to leave irb, and then type 'clear' to clear the screen.

This action will cause you to lose all the work in irb.

hi, if you are on Windows, inside IRB you should type system('cls') like this:

irb(main): 007:0>system('cls')

Yes, that's it! Thank you. In the ruby console (irb), on the Mac, ctrl+l (control + lower case L) clears the screen. The "clear" command will clear screen in Workspaces, but not in the ruby console.

I want to keep all the items I am working on in workspaces while in irb, but the clear command does not work. If I quit irb I go back to the default and relaunch irb, my previous work got erased. Hope somebody can help on this one as I think this was not covered on the video.

I tried to look it up and it seems like that's not something that can be done in Windows. It only works on Linux and Mac.

I know this is a really old question but if anyone looks. On windows system 'cls' works.

EDITED: Typing "clear" doesn't work in the irb section of the console.

I'm using Windows and ctrl and "L" does work, thank you!
