How To Install Man Page Files on Ubuntu

Ubuntu 3

In this guide, we will walk you through the process of installing man page files on Ubuntu. Man pages, short for manual pages, are the form of software documentation that is available on almost every Unix-like operating system, including Ubuntu. They provide a detailed reference for each command or software that could be run on your system.

Quick Answer

To install man page files on Ubuntu, you need to determine the section number of the man page, copy or symlink the file to the appropriate directory, update the man command’s internal database, and then view the installed man page using the man command. Additionally, if you only need to install the man page locally, you can set the MANPATH environment variable.

Understanding Man Page Sections

Before we dive into the installation process, it’s important to understand the structure of man pages. Man pages are divided into sections, numbered 1 through 8, each representing a particular area of the system. For instance, user commands belong to section 1, system calls to section 2, and so on. You can refer to the man page for the man command to understand the different sections and their corresponding numbers.

Installing Man Page Files on Ubuntu

Step 1: Determine the Section Number

The first step is to determine the section number of your man page. As mentioned earlier, most command man pages belong to section 1.

Step 2: Copy or Symlink the Man Page File

Next, you need to copy or symlink the man page file to the appropriate directory. We recommend using the /usr/local/share/man directory for files installed without using the APT package manager. If your man page belongs to section 1, copy or symlink it to /usr/local/share/man/man1/.

To copy the man page file, you can use the cp command:

sudo cp examplecommand.1 /usr/local/share/man/man1/

In the above command, cp is the command to copy files, sudo is used to execute the command with root permissions, examplecommand.1 is the man page file you want to copy, and /usr/local/share/man/man1/ is the destination directory.

Alternatively, you can create a symbolic link (symlink) to the man page file using the ln command:

sudo ln -si "$PWD/examplecommand.1" /usr/local/share/man/man1/

In the above command, ln is the command to create links, -s makes it a symbolic link, -i makes ln ask you if you want to overwrite an existing file, "$PWD/examplecommand.1" is the source file, and /usr/local/share/man/man1/ is the destination directory.

Step 3: Update the Man Command’s Internal Database

After copying or symlinking the man page file, you need to update the man command’s internal database. This can be done by running the mandb command:

sudo mandb

In the above command, mandb is the command to create or update the database of manual pages, and sudo is used to execute the command with root permissions.

Step 4: View the Installed Man Page

Finally, you can view the installed man page by running the man command followed by the section number and the name of the command:

man 1 examplecommand

Installing Man Page Locally

If you only need to install the man page locally, you can set the MANPATH environment variable to include the directory where your man page is located. For example, if your man page is in ~/share/man/man1/, you can add the following line to your ~/.bashrc or ~/.profile file:

export MANPATH="$HOME/share/man:$MANPATH"

After saving the file, you need to restart your terminal or run source ~/.bashrc (or source ~/.profile) for the changes to take effect. Now you can view the man page by running man examplecommand.

Conclusion

Man pages are a crucial part of any Unix-like system, providing detailed documentation for commands and software. By following the steps outlined in this guide, you should be able to manually install man page files on Ubuntu. Remember to always refer to the official Ubuntu Manpage Repository for the most accurate and up-to-date information.
