NAME
intro - Introduction to commands
DESCRIPTION
Section 1 describes the commands available for all Tru64 UNIX users.
Some reference pages in this section may contain suffixes to allow their files to exist with those of other reference pages having the same
base name and section number. When used, suffixes are made up of one to four letters. See the man(1) reference page for more information
on suffixes.
Commands related to system maintenance appear in Section 8.
ERRORS
On 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. For more information, see exit(2). The first byte is 0 for normal termination; the sec-
ond byte is customarily 0 for successful execution. A nonzero status indicates a problem, such as erroneous parameters, or bad or inacces-
sible data. The status value is called variously exit code, exit status, or return code, and is described explicitly on reference pages
only when special conventions apply.
