Locate, read, and use system documentation including man, info, and files in /usr/share/doc

To locate, read, and use system documentation, including the man pages, info pages, and files in the /usr/share/doc directory, you can follow these steps:

1. man command: The man command is used to display the manual pages for various commands and system functions. To use it:

   man <command>

   Replace <command> with the name of the command or topic you want to learn about.

   Example:

   man ls

   This command will display the manual page for the ls command, which provides information about how to use it and what options are available.

2. info command: The info command is another way to access documentation, particularly for GNU software. To use it:

   info <command>

   Replace <command> with the name of the command or topic you want to learn about.

   Example:

   info tar

   This command will display the documentation for the tar command in the Info format, which provides detailed information about the command and related topics.

3. /usr/share/doc directory: The /usr/share/doc directory contains additional documentation files for installed packages on your system. You can browse and read these files using standard file exploration tools such as ls or cat.

   Example:

   ls /usr/share/doc

   This command will list the contents of the /usr/share/doc directory, showing the available documentation files.

   To read a specific file:

   cat /usr/share/doc/<package>/<filename>

   Replace <package> with the name of the package you're interested in and <filename> with the name of the documentation file.

   Example:

   cat /usr/share/doc/coreutils/README

   This command will display the contents of the README file located in the /usr/share/doc/coreutils directory.

By using these methods, you can access and utilize the system documentation, which is crucial for the RHCSA certification exam and general system administration tasks.
