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