What is a .2 file?
The file extension .2 refers to a Unix Section 2 Manual Page. This type of file contains documentation specifically about system calls, which are ways that a program requests a service from the operating system's kernel. Each .2 file is specifically named after the system call it explains, making it easier to find information about that particular call.

Additionally, .2 files are plain text files, so they can be opened and read using any standard text editor. Popular text editors that can handle .2 files include Vim and GNU Emacs, both of which are available on many operating systems and provide powerful tools for editing text. Other basic text editors like Nano, Gedit, or even Notepad on Windows can also be used to view .2 files, although they won't provide the formatted view you get with the 'man' command.
