Man is also a UNIX command like ls or cat.I am also updating the UNIX a few examples for the man command.
The POSIX specification requires man to support only one option (-k) and most of the UNIX systems also offers the apropos command that emulates man -k.When used with this option it prints the one line description of the command that emulates man-k.When used with this option,man searches summary database and prints a one liner description of the command.


Code
  1. man-k awk

    2. 

  2. --it prints 

    3. 

  3. awk awk(1)  - pattern scanning and processing language

    4. 

  4. nawk nawk(1) - pattern scanning and processing language

    5. 

  5. man man  //Viewing the pages with man

    6. 

  6. man wc    //Help on wc command
