.Sh NAME
|
|
.Nm intro
|
|
.Nd introduction to general commands (tools and utilities)
|
|
.Sh DESCRIPTION
|
|
Section one of the manual contains most of the commands
|
|
which comprise the
|
|
.Bx
|
|
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.
|
|
.Pp
|
|
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
|
|
.Xr sysexits 3 ,
|
|
while others simply set the status to an arbitrary value >0 (typically 1).
