Introduction to general commands (tools and utilities)
Overview
The manual pages in section 1 contain most of the commands which comprise the BSD user environment. Some of the commands included in section 1 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.
