NAME

intro − introduction to commands

DESCRIPTION

This section describes publicly accessible commands in alphabetic order.  Certain distinctions of purpose are made in the headings:

(1) Commands of general utility, many with enhancements from 4.3 BSD.  Wherever possible, we have incorporated System V versions of commands and utilities into our standard UNIX release.  Where a command has both a System V and a BSD version, and it has been possible to merge them, we have done so.  In some cases, where the System V version was compatible with BSD and offered significant added value, we adopted that version as our standard. 

(1C) Commands for communication with other systems. 

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

(1V) Optionally installed commands from System V, or commands with versions from System V. 

These commands either depend upon System V functionality, or have incompatibities with the corresponding BSD version.  They are included in the System V Software installation option.  Once installed, they can be found in the directory /usr/5bin. 

In most cases, versions that differed were similar enough so that only the differences for the System V version needed to be noted on the manual page.  In a few cases, however, a different manual page for each version was required.

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 and exit(2). 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.
