INTRO(1) General Commands Manual INTRO(1)NAME
intro - introduction to commands
This section describes publicly accessible commands in alphabetic order. Certain distinctions of purpose are made in the headings:
(1) Commands of general utility.
(1C) Commands for communication with other systems.
(1G) Commands used primarily for graphics and computer-aided design.
N.B.: Commands related to system maintenance used to appear in section 1 manual pages and were distinguished by (1M) at the top of the
page. These manual pages now appear in section 8.
Section (6) for computer games.
How to get started, in the Introduction.
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 cus-
tomarily 0 for successful execution, nonzero to indicate troubles such as erroneous parameters, bad or inaccessible data, or other inabil-
ity 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.

INTRO(8) BSD System Manager's Manual INTRO(8)NAME
intro -- introduction to system maintenance procedures and commands
This section contains information related to system operation and maintenance.
It describes commands used to create new file systems (newfs(8)), verify the integrity of the file systems (fsck(8)), control disk usage
(edquota(8)), maintain system backups (dump(8)), and recover files when disks die an untimely death (restore(8)). Network related services
like inetd(8) and ftpd(8) are also described.
All commands set an exit status. Its value may be tested to see if the command completed normally. Unless otherwise noted (rare), the value
0 signifies successful completion of the command, while a value >0 indicates an error. Some commands attempt to describe the nature of the
failure by using error codes defined in sysexits(3), or set the status to arbitrary values >0 (typically 1), but many such values are not
described in the manual.
A number of pages in this section describe general system management topics.
For example, the boot(8) manual page describes the system bootstrapping procedures, and the diskless(8) manual page describes how to boot a
system over a network. The crash(8) manual page should be consulted to understand how to interpret system crash dumps.
The intro section manual page appeared in 4.2BSD.
