There are certain C functions whose names are ambiguous with the Ubuntu commands eg: getopt. How do I view the man page of these functions? No doubt it is easily available on the internet but I am keen to not leave the terminal as far as possible.
Use the format man [section] name (e.g. man 3 getopt) where section can be one of the followings:
1 User Commands
2 System Calls
3 C Library Functions
4 Devices and Special Files
5 File Formats and Conventions
6 Games et. Al.
7 Miscellanea
8 System Administration tools and Deamons
Consult man man for more information.
