 Many of us are probably familiar with the where is command. So you can say where is bash, and it will tell you where the bash files are, or where is nmap. And it will tell you where those files are. You can see where the executables are, and the man files for it, so it gives you that type of information. And that's commonly known. I've known about this since I started using Linux, it was one of the first commands I learned. But I recently found out that there is another command that is the what is command. And I think it's pretty straightforward on what it does, so let's go ahead and have a look at it. I'm going to say what is bash, and what it's going to do is it's going to give you a one line description on what that program is. So there's what is bash, what is nmap, what is ifconfig. So it makes it very simple, if there is a command that you have installed, and you're not really sure what it is, obviously you can open up the man page by saying man ifconfig. And you'll get a full description on how it works, and there should be a description here explaining what it is. But quickly without going into an interface like that, you should be able to use the what is ifconfig. Oops, of course you've got to spell the command properly. And so yeah, I just thought I'd share that with you, I know this was a real quick one. But it could be very useful, just finding out what commands are, especially if you're looking at a script someone else wrote and you're going through it and you're wondering what a command does, to get a one line description like this is so convenient and so easy and quick, and you're like, oh okay, and then if you want to know more, you can obviously go into the man file and get a longer description and see how the command actually works if the man page is written well. So anyway, that is the what is command. And yes, if you're wondering, you can what is, what is, and it will tell you, it plays one line manual page descriptions. So I do thank you for watching again. I wrote the two minute mark here. This is not a very long video, but I found this command very useful and quick and easy. So I thought that I'd share it with you.
