INTRO(1)                    General Commands Manual                   INTRO(1)



NAME
       intro - introduction to commands

DESCRIPTION
       This  section  describes  publicly  accessible  commands  in alphabetic
       order.  Commands of general utility, many with  enhancements  from  4.3
       BSD.

       Pages of special interest have been categorized as follows:

       1C        Commands for communicating with other systems.

       1G        Commands  used  primarily  for  graphics  and  computer-aided
                 design.

       1V        System V commands.  One or more of the following are true:

                 o  The man page documents System V behavior only.

                 o  The man page documents default SunOS behavior, and  System
                    V behavior as it differs from the default behavior.  These
                    System V differences are presented under SYSTEM V  section
                    headers.

                 o  The  man  page  documents behavior compliant with IEEE Std
                    1003.1-1988 (POSIX.1).

          files and macro packages for document preparation.

DIAGNOSTICS
       Upon termination each command returns two bytes of status, one supplied
       by the system giving the cause for termination, and  (in  the  case  of
       "normal"  termination)  one  supplied  by the program, see wait(2V) and
       exit(2V).  The former byte is 0 for normal termination, the  latter  is
       customarily  0  for  successful execution, nonzero to indicate troubles
       such as erroneous  parameters,  bad  or  inaccessible  data,  or  other
       inability  to cope with the task at hand.  It is called variously "exit
       code," "exit status" or "return code," and is described only where spe-
       cial conventions are involved.
