am a new Unix / Linux user. I am using whatis
command to find man pages. But, I noticed that some man pages have a common names. For example, when I run whatis printf
printf (1) - format and print data
printf (1p) - write formatted output
printf (3) - formatted output conversion
printf (3p) - print formatted output
printf [builtins] (1) - bash built-in commands, see bash(1)
How do I access overlapping man pages and what is the meaning of (1), (1p), (3), and so on?
have CentOS 5/6/7 server located in a remote data center. How do I get more help about command and its syntax on Linux or Unix-like system from a shell prompt?
