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:

    •   The man page documents System V behavior only.

    •   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.

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

SEE ALSO

•   Section 8 in this manual for system administration procedures, system maintenance and operation commands, local daemons, and network-services servers.

•   Section 7 in this manual for descriptions of publicly available files and macro packages for document preparation.

•   Section 6 in this manual for computer games.

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 special conventions are involved.
