intro(1) — Commands
NAME
intro − introduction to commands
DESCRIPTION
Section 1 describes the commands available for all DEC OSF/1 users.
The suffixes used on some reference pages are used only to allow reference pages with the same base name to exist on DEC OSF/1 systems. 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
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. For more information, see exit(2). The former byte is 0 for normal termination; the latter is customarily 0 for successful execution. A nonzero status indicates a problem such as erroneous parameters, or bad or inaccessible data. The status is called variously exit code, exit status, or return code, and is described only where special conventions are involved.
