 Hello and welcome. This is part of a series. I sure hope that you check out the full playlist There should be a link in the description or at the end of this video and not only this playlist But I have hundreds of shell scripts tutorials just check my website films by chris.com. That's Chris the K There's a link in the description. So we're gonna be looking at the help command a lot of you may be familiar with the man Command which is the manual command. If not, you really should you're probably looking up stuff online Don't need to for those of you who are unfamiliar Most programs in the shell you can type in man And I'll give you an example will do end map and it will give you a manual on how to use that program and a good man page We'll have examples as well as I talked about in previous videos So lots of options here in the end map man page But what happens when you do something like I don't know have a command like Type Which we talked about in the previous video. We also talked about the command command Let's go ahead and type in man command. Oh, no manual entry What if I type in man tight? Well, there is but it's not the command. We're looking for These are built-in functions into the shell and although there might be notes on it if you were to Like man bash if you're in a bash shell Which is a very long man page because there's lots of commands built in and there might be some information in there on These commands since they're built-in commands, but it's a long man page and yes, you can search through it But there's an easier way the help command the help command so we can type in help and type and I get an error here and that's because Help is not built into Z shell, which I'm currently using here So but if you're running bash, I can type in help And I can type in the type command and here we go. I get a little help Display here basically just just like a quick little man page You know some programs have this built-in you type in the command and help But in this case I have the help command and I can also you do command and I get the command Help page so remember when you're working with different shells not everything might be there built-in functions might be different And if I command help Oh, sorry command-v help. Let's see what happens here. It tells me it's a built It's built into the shell if I exit back out here. What happens if I do? Command-v here. I'm curious. I haven't tried this yet see it's not found because It's built into bash. It's not built into Z shell There might be something similar in Z shell that I'm familiar unfamiliar with So that's important to know. So so now we've looked at using the type and command command to To see where programs are and we can find out which ones are built into the shell and which one are external programs And if it's built in and there's no man page sometimes there is sometimes they're not But the help command will help you but only if it's built into your shell so Again if you're in bash help and the name of the command such as command And you'll get the help page So That's it for this tutorial. I do hope that you're enjoying it. It was a quick one And yeah, I love Z shell and but I also love bash and it's a shame There's no the help command isn't built in but again there might be something else I'm unaware of if there is let me know in the comments if you like my videos You like these shell script tutorials be sure to keep on watching subscribe so you don't miss any There's a full playlist in the link of the description of this video Hopefully at the end of this video as well if I don't forget to put it there And again, I have hundreds and hundreds of shells script videos in the past check out my website films by Chris comm That's Chris the K There's a link in the description there You can search through all my videos from both my channels and also think about supporting over at patreon.com 4 slash malex 1000 or with PayPal you can find that in the support section on my website If you can't support me that way it really does help if you share these videos like these videos watch these videos and I'm not gonna lie.
