The more command is a useful Linux shell command for navigating through text files. It is a powerful tool for anyone familiar with the command line, as it allows you to search through text-based data without having to open the file in an editor. This can be done in both single page and multi-page views.
The more command works by opening a file in a way similar to most text editors, displaying one page of the text at a time. To open a file using more, type more [filename], replacing filename with the file you wish to view. For example, to open example.txt, type more example.txt.
As you use more, you will notice that you are able to scroll up and down pages. You can also search for certain words in the file by pressing /, followed by the word you are looking for. To exit more, press q.
You can also combine the more command with the cat command for longer files. By using cat, you can output the entire contents of the file, line by line, and then pipe the output to more. The syntax for this is cat [filename] | more, which will then open the file in the same way as described above. This can be very useful when dealing with files with large amounts of text.
In conclusion, the more command is a great way to quickly navigate through a text-based file in a terminal window. It can be used on its own or combined with cat to quickly search through larger files. With a bit of practice, using more becomes an invaluable tool for any system administrator.
