Unix for the most part does try to give you help when it can. After perusing the online help, you may find that it is for the most part, very well written, to the point and easy to get the information you need without having to wade through endless pages of documentation. For this reason, you may prefer to use the online manuals instead of this guide or a book after you have used them a couple of times. The basic format for retrieving online help is:
man section command
where command is replaced with the command you are wanting help on. If the manual for that command can be found it will then start printing it to the screen one page at a time. Use the space bar to see the next page, press the enter (or return) key to see the next line in the manual, or press the letter 'q' to exit help and return to your prompt. The section corresponds to which manual section you are wanting to look for the command in. This argument is totally optional and isn't usually needed, unless you know where you are looking for something. The following are standard unix manual sections and what is typically found in them.
Manuals are typically formatted under section headings. Here is an example manual of the imaginary xxx command (You'll note that it is located in section 1 of the manual):
XXX(1) UNIX Programmer's Manual XXX(1) NAME xxx - imaginary unix command SYNOPSIS xxx [-xX] DESCRIPTION Xxx, without an argument, does nothing, since it's totally imaginary. Users who specify an argument are advised to contact their local unix guru for spiritual guidance. The file /usr/adm/xxx logs names of users who attempt to use this command for CIA background checks. OPTIONS -x Imaginary argument that does nothing. -X Another imaginary argument that does nothing, but in a more complex way. FILES /usr/adm/xxx SEE ALSO guru(1), cia(8) BUGS This command doesn't even exist. CIA background checking sometimes fails. Revision 1.4 86/05/13 1
Typical manual subject headings are:
