To read a simple file in Bash, we can also use the cat command to view a document. So let's look at important document. The cat command is similar to the Windows cat command, since it doesn't do a great job at viewing large files. Instead, we use another command, less. Less does a similar thing that more does for Windows, but it has more functionality. Fun fact, there's a Bash command called more, but it's been slowly dying out in favor of less. It's literally a case of less is more. Similar to more, when we use less we're launched into an interactive shell. Some of the most common keys you'll use to navigate this tool are the up and down keys, page up and page down. g, this moves to the beginning of a file. You can see now we're at the beginning. Capital G, this moves to the end of a text file. Now we're at the end. Slash and then a word_search. This allows you to search for a word or phrase. If I type in slash then type the word I want to search for, I can scan through the text file for words that match my search. Q, this allows you to quit out of less and go back to your shell, similar to the q key in the Windows more command. Do you see how less offers functionality like searching within a file? Less is a great tool to use to view files of any size. You'll no doubt end up using this command often as an IT support specialist. Similar to the Windows cat and head parameter, we can do the same thing in Linux using a command called head. This will show you, by default, the first ten lines of a file. Now what if you wanted to view the last few lines of a file? You can use a command called tail. This will show you, by default, the last ten lines of a file.
