INTRO(1) BSD General Commands Manual INTRO(1)NAMEintro — introduction to general commands (tools and utilities)
DESCRIPTION
Section one of the manual contains most of the commands which comprise
the BSD user environment. Some of the commands included in section one
are text editors, command shell interpreters, searching and sorting
tools, file manipulation commands, system status commands, remote file
copy commands, mail commands, compilers and compiler tools, formatted
output tools, and line printer commands.
All commands set a status value upon exit which may be tested to see if
the command completed normally. Traditionally, 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 errors codes as defined in sysexits(3), while others simply set the
status to an arbitrary value >0 (typically 1).
