Man pages serve as a valuable resource for Linux users, providing detailed information and instructions on various commands and utilities. However, accessing and viewing these pages can be a bit cumbersome, especially for those who prefer a more visual format. This is where the ability to convert man pages to PS or PDF comes in – providing a more organized and easily distributable version of the manual pages. In this article, we will explore the process of converting man pages to PS or PDF format from the Linux command line, and how it can enhance the user experience for those working with Linux systems.

How to Convert Man Pages to PS or PDF Format from the Linux Command Line
Man pages, short for manual pages, are a form of documentation in Linux and other Unix-like operating systems. They provide detailed information and instructions for various commands, system calls, library functions, and file formats. While man pages are easily accessible from the command line, users may sometimes require a printed or PDF version for offline reference or distribution. In this blog, we will discuss how to convert man pages to PS (PostScript) or PDF format from the Linux command line.
Converting Man Pages to PS Format:
Step 1: Install the “groff” Package
To convert man pages to PS format, we need to install the “groff” package, which contains the necessary tools for creating PostScript and PDF files from the terminal. The package is available in most Linux distributions and can be installed using the following command:
sudo apt install groff #for Debian based distributions
sudo yum install groff #for RedHat based distributions
Step 2: Locate and Navigate to the Man Page Directory
Navigate to the directory where you have the man pages you want to convert. The default location for system man pages is “/usr/share/man” and for user-installed man pages is “/usr/local/share/man”. You can check the location of the man pages using the “manpath” command:
Step 3: Convert Man Page to PS Format
To convert a man page to PostScript format, we will use the “man” command with the “-t” option, which outputs the man page in roff format suitable for post-processing. We can then use the “groff” command with the “-man” macro package and the “-Tps” option to create the PS file. For example, to convert the “ls” man page, we will use the following command:
man -t ls | groff -man -Tps > ls.ps
Step 4: View the Output PS File
The converted PS file will be saved in the current directory. You can use a PS viewer like Ghostscript, Okular, or Evince to view the file or print it using a PostScript printer.
Converting Man Pages to PDF Format:
Step 1: Install the “ghostscript” Package
To convert man pages to PDF format, we need to install the “ghostscript” package, which contains the necessary tools for creating PDF files from the terminal. The package is available in most Linux distributions and can be installed using the following command:
sudo apt install ghostscript #for Debian based distributions
sudo yum install ghostscript #for RedHat based distributions
Step 2: Create PS File
Use the above steps to create a PS file of the man page you want to convert.
Step 3: Convert PS to PDF Format
To convert the PS file to PDF format, we will use the “ps2pdf” command, which is part of the “ghostscript” package. Simply run the following command with the name of the PS file:
Step 4: View the Output PDF File
The converted PDF file will be saved in the current directory. You can open it with any PDF viewer or print it.
In conclusion, converting man pages to PS or PDF format from the Linux command line is a quick and straightforward process. It can be useful for creating offline documentation or sharing man pages with others who may not have access to a Linux system. Just remember to install the necessary packages and use
After exploring the various methods and tools available for converting man pages to PS or PDF format from the Linux command line, it is clear that such a task can be easily accomplished with the right approach. Whether using the built-in tools like groff or the more user-friendly programs like man2pdf, Linux users can efficiently and effectively convert man pages to these commonly used formats for easier accessibility and sharing. This process not only allows for convenient offline access to essential technical information, but it also showcases the versatility and customization options available on the Linux operating system. With this knowledge in hand, users can confidently navigate the command line and manipulate their man pages for their specific needs. Overall, understanding how to convert man pages to PS or PDF format adds another useful tool
