In this movie, Sandra shows how to get help for your new installation of Red Hat Enterprise Linux.
- [Narrator] In this video, we'll practice…some different ways to find help at the command line.…Bash allows users to run hundreds of commands,…so it's practically impossible to know every command…and all the different ways each command can be used.…One way to get help is to use the help option.…From the shell prompt, you can type the command,…followed by dash help, to see a summary of that command.…Let's try this with the Wget command.…Wget is a command line utility that downloads…files over a network.…First, we'll type the command,…then we'll add a dash h or…dash help option, and hit enter.…
You can see that the help pages are pretty extensive.…Let's try this again.…This time we'll do the same thing, we'll run the help option…on the Wget command, but we'll take the output of that…and we'll pipe it over to a less command…so we can see the output in an easier to read,…page by page format.…To do this, we'll run the same command that we just ran.…Instead of typing it out, I can just…hit the arrow key, upward.…Now we'll want to add a pipe.…
