NAME
intro - introduction to commands
DESCRIPTION
This section describes publicly accessible commands for gen-
eral utility. In addition, some special commands for com-
munication purposes are described. All commands are listed
in alphabetic order, and each is suffixed by ``(1)'' to help
identify its place in the DOMAIN/IX Command Reference for
System V.
N.B.: Commands that relate to system maintenance, dis-
tinguished by (1M) in earlier UNIX System documentation, are
described in the DOMAIN/IX Administrator's Reference for
System V.
DIAGNOSTICS
Upon termination, each command returns two bytes of status;
one is supplied by the system giving the cause for termina-
tion, and (in the case of normal termination) one supplied
by the program. The former byte is 0 for normal termina-
tion; 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 exit code, exit status, or
return code, and is described only where special conventions
are involved.
