introduction to general commands (tools and utilities)
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. The exit values and their meanings
are explained in the individual manuals. Traditionally, the value 0
signifies successful completion of the command.
