 Okay, so let's make a new script. Okay, so the point of this video is to show you how to execute a command without having to type the dot slash like this. So normally, if you want to execute a command, you would have to do something like this. That's fine. If I type something like this, that's not going to work. It's going to ask me to install a package called hello depending on your system. So the question is, how do we make it so that this command, I'm just going to click that one. So what I'm going to do is I'm going to show you how to make it so that when you execute, let's say, this command, you don't have to put the dot slash right before it. Now to get into the details of how this works, your path variable is responsible for keeping a list of directories in which executables are stored. Now to fix this, and when I say this, I am talking very loosely, we need to add the current directory to your path. So do something like this. Keep in mind, when you add a new directory, you have to separate it with the colon getger and enter. Now, the system will look for commands first in all of your standard locations and then in the current directory. If you want, you can even list out all the locations your path variable knows about. So to do that, we can do something like this. As you can see, the path variable knows about the current location. So as you can see, these are all the standard locations where Unix or Linux usually looks for executables. And then finally, we have the current location down here. Anyways, to prove that this actually works, let's execute hello. Okay, that works. Now let's try asking this without the dot slash the beginning. And that works as well. Now again, this is something you should probably not do because what happens is any directory you visit now will become a candidate for commands to execute. Since we define our path variable with the current directory being at the end, bash will check all of the standard locations first, then it's going to go to the current directory we're in and then look for commands there. Just to show you again, if I echo out, as you can see the current directory is at the end, meaning it will be checked last. But if we add a dot at the beginning, that changes everything. So if we do something like this, and let's try redaming to something else. Let's rename it to a standard utilities, just cat. Now let's try catting out anything, just say cat, then I want to cat out everything in this directory. And it says hello. Now I hope you realize why this is something you don't want to do. Anyways, now don't let me stop you from doing this. If you want, it's fine to add your current directory as the last item in your path. But again, it's not recommended. So anyways, that's it for today. If you enjoyed this video, remember to like and subscribe and all that jazz. And I will see you later.
