INTRO(1) General Commands Manual INTRO(1)
intro - introduction to commands
This section describes publicly accessible commands in alphabetic
order. Commands of general utility, many with enhancements from 4.3
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
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
o The man page documents behavior compliant with IEEE Std
o Section 8 in this manual for system administration procedures, sys-
tem maintenance and operation commands, local daemons, and network-
o Section 7 in this manual for descriptions of publicly available
files and macro packages for document preparation.
o Section 6 in this manual for computer games.
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.
