So there's gonna be fairly simple video. Let's create a variable called my var So I'm in a bash cell right now. I'm gonna say my var equals. This is my string And I can echo dollar sign My var if I could type there we go and it echoes out the string I can add that I can say I go my var. This is my string that I created And it goes out that but still my var still equals. This is my string Let's say for some reason you're creating a script and you want to un-set a variable at some point So you're using it, but then you want to un-set it so that It's not being used anymore and maybe you're doing a check later on to see if that variable still exists Whatever your reason for it. We're gonna say unset. It's that simple unset and the name of your variable my var in this case And it's now unset if I try to echo out my var. You can see that it is empty. It is blank There's nothing there. I can go up into this it says echo my var that I had I created and all it's gonna say is That I had created because that variable no longer exists And yes, this is a very short video But it could be very useful.
