.TI GENERAL Introduction to Help .sp 2 The Unix "help" command displays documentation on various topics. If you type help from the Unix shell, you will see a list of the major topics that help knows about and a set of instructions for perusing them. If one of the topics were "topic", you could skip directly to information relating to "topic" by typing help topic from the shell, and after seeing the documentation you would be returned directly to the shell. The help topics are intended to provide Unix documentation written for inexperienced users, as well as coverage of various non-standard features of the local Unix system. Another command that displays on-line information is "man", which shows you the section from the Unix Programmer's Manual for a particular command or system feature. The documentation it produces is terse and difficult, and, if used correctly, comprehensive. To see the manual page for the "ls" command, for example, type man ls Help has several indexes in which to look for subjects you request. They help you locate references to help, man, and off-line documentation. To find out briefly what each topic is about, type "index_help" (no quotation marks) as a topic.
