What else can be done with hidden files in Linux once they are listed?

There are many things that can be done with hidden files in Linux once they are listed. For example, you can use them to store temporary files or configuration information.

How do hidden files work in general?

When you open a file in Linux, the operating system looks for a special type of file called a "hidden file." A hidden file is one that's not displayed when you browse your computer's files. You can't see it unless you use the command line or special software.

Most of the time, hidden files are used to store important information. For example, if you're using Linux to run a web server, you might put all your configuration files for the server in a hidden directory so that nobody but you can see them.

You can create and manage hidden files using the command line or special software. To view all the hidden files on your computer, use the ls -a command:

ls -a /usr/share/doc/HTML-Kitchen-1.0/hidden*
