**3. Getting Help While on the System**

The full set of man pages is organized into many sections having titles such as:

commands games library routines system maintenance special files device drivers file formats system calls miscellaneousOn most UNIX systems, you can find out what the categories are by typing:

If you know the name of a command, you can view its man page at your terminal. If you don't know its name, you can use theapropos intro

whereapropostopic

which would produce a list of man pages that contain ``fortran'' in their header lines:apropos fortran

If you omit theman [section]name(on Solaris systems,man [-ssection]name)

Most manual sections have an ``intro'' man page, describing that section in general. So to find out more about library functions (section 3 of the man pages), type

From there, you have access to various forms of documentation, FAQs, and system resources.http://www.hardlink.net/support.html
