NAME

       intro - Introduction to commands

DESCRIPTION

       Section 1 describes the commands available for all Tru64 UNIX users.

       Some reference pages in this section may contain suffixes to allow their files to exist with those of other reference pages having the same
       base name and section number. When used, suffixes are made up of one to four letters.  See the man(1) reference page for  more  information
       on suffixes.

       Commands related to system maintenance appear in Section 8.

ERRORS

       On  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.  For more information, see exit(2).  The first byte is 0 for normal termination; the  sec-
       ond  byte is customarily 0 for successful execution. A nonzero status indicates a problem, such as erroneous parameters, or bad or inacces-
       sible data. The status value is called variously exit code, exit status, or return code, and is described  explicitly  on  reference  pages
       only when special conventions apply.
