INTRO(1) General Commands Manual INTRO(1)
intro - introduction to general commands (tools and utilities)
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.
