39.Nm intro
40.Nd introduction to general commands (tools and utilities)
41.Sh DESCRIPTION
42Section one of the manual contains most of the commands
43which comprise the
44.Bx
45user environment.
46Some of the commands included in section one are
47text editors, command shell interpreters,
48searching and sorting tools,
49file manipulation commands,
50system status commands,
51remote file copy commands, mail commands,
52compilers and compiler tools,
53formatted output tools,
54and line printer commands.
55.Pp
56All commands set a status value upon exit which may be tested
57to see if the command completed normally.
58Traditionally, the value 0 signifies successful
59completion of the command, while a value >0 indicates an error.
60Some commands attempt to describe the nature of the failure by using
61exit codes as defined in
62.Xr sysexits 3 ,
63while others simply set the status to an arbitrary value >0 (typically 1).
