nroff command is a Unix tool that is used for preparing documents for dot matrix printers and terminals. It stands for “Nontypesetting RunOFF”. With the help of text editors, troff codes are inserted into the text, and then the nroff command is used to transform the material into the desired output.
How does nroff command work?
The troff codes are used in the text to format the content such as font, size, indentation, etc. The nroff command then reads these codes and generates the output as per the instructions given in the codes. This process is also used for creating man pages in Unix.
What are the benefits of using nroff command?
The nroff command is used for printing documents on dot matrix printers and terminals that do not support typesetting. The output generated by nroff is simple and easily readable. It also allows the user to customize the font, size, and indentation of the text. Additionally, nroff can create links and references within a document, which can be helpful for creating manuals and reference guides.
Conclusion
nroff command plays a significant role in creating and formatting text-based documents in Unix. Its usage is more prevalent in cases where typesetting is not supported. With nroff, the user can easily format the text as per their requirements and generate simple yet easily readable output.
Frequently Asked Questions (FAQs)
What is the difference between troff and nroff?
The troff command is used to generate output for typesetting devices such as printers, while the nroff command is used for output on devices that do not support typesetting such as dot matrix printers and terminals.
Can nroff be used for creating man pages in Unix?
Yes, nroff can be used for creating man pages in Unix.
Is nroff still used?
Yes, nroff is still used for creating and formatting text-based documents in Unix.
Can nroff generate links and references within a document?
Yes, nroff allows the user to create links and references within a document, which can be helpful for creating manuals and reference guides.
Final Thoughts
nroff command might not be widely used especially in today’s digital era where printers and terminals support high-quality typesetting. However, it still holds significance in the Unix world because of its capability to format text for output on devices that lack typesetting support.
