intro - introduction to general commands (tools and utilities)
The manual pages in section one contain 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.
