 Okay, and welcome to 2018 this video is the beginning of a series for my shell script tutorials in 2018 I've done many show scripts in the past over the years, but this is the series. I'm doing in 2018 I'm gonna learn a lot this year be sure to check out the full playlist in the link in the description or at the end of This video again, so to be the first I'll be releasing a bunch over the coming weeks So let's go ahead and quickly jump in the show if you've used the shell at all with something that's very useful are man pages manual pages and so you can type in man and the Command you want to know about so in this case like LS is for listing directories You can hit man LS and then you can go through here and look at all your options for that program Q to get out of that you can also do something like make dirt and it will give you the Instructions the manuals for that or something like BC, which has a very long man page with a lot of stuff in here And I always say a good man page will always have examples But sadly a lot of man pages don't have any examples on how the commands work So how can you find minutes? Of course you can go and Google this command and see some examples But there's actually a website right here called cheat that sh And it's very simple to use up here at the top You can click this little box up here and type in the command or click the drop down to see a full list And you can see they have lots of commands In here already with some cheat sheets. So in here I can type in LS and hit enter And it'll give us some very quick examples on the LS command that you can play with or we can go make dirt and you can see some examples of that or BC and if you were to type in part of a command, so let's say I type in dir It's going to say. Oh, did you mean dir s make dir? Remove dir and you go. Oh, yeah. Yeah. Yeah, I wanted remove dir And it will give you some examples on that and you can even do things like said and it'll give you some examples on said or Lots of just few examples that you can copy and paste but again, we're doing this in the web browser working in the shell Maybe we don't have a web browser not a problem. Of course if you look right here It tells you exactly what the command is and we go back to our home directory on this website You can see it tells you right here show the show cheat sheet I do curl the website and forward slash command and it's going to output so in here. I can say curl Cheat dot sh forward slash ls and it gives us the same examples or make dir or said or even Lock and you can course copy and paste these examples. So here this last example knock is Fine output separator for characters. So let's say we had this input of one two three with spaces Well, we can say well, let's in between each one of those numbers. I need to send my colon That's exactly what this command does here. We do that so very quick and easy to See commands some examples for them examples are great It's gonna save you some googling and you know man pages are great to get the details But if you just want to see how program works, it's nice to have a command you can copy and paste and go Okay, I got an idea on how this works instead of trying to go. Oh, okay so I say semi colon begin and then OFS and then you know, it's easy to have an example right there And it's a quick and easy way to do it. You can look at it in the web browser You know on your phone or your desktop But again, you can do the same exact thing in your shell without leaving it You can use curl or though. I'm sure that if we were to use W get with Dash Q for quiet and capital O dash for standard output. We get the same thing Let's close for you to make that a little cleaner. There we go So you can use W get if that's all you got. It's one of those things. I Love curl. I think it's a little more advanced than W get but W gets on pretty much every Linux system Even if you're working on a router or something. It's just there because it's built into things like busybox So it's nice to know how to both work. So there you go. I do. Thank you for watching again This is part of a series.
