The Naming Conventions
 

In man pages or online documentation, a newbie often encounters something like this: nmake[4], Perl[3], and so on. What are these numbers and what do they mean?

You know what? I don't know. :)

But the great thing about man pages is that they are so extensive. Try the following:

$ man man

Let us know what you find out! (I'm not being smart.)

Hmm, now that you got me curious, I had to look it up. I found it (no surprise) in rute:

Not so mysterious. :D

I found out that if you type for exampleyou find out at the top left and top right something likeIt may mean that this Section 1 of the man page for perl

See above. ;)

Just remember that the "sections" are not sections *within* the man page, but the section the man page belongs to. For instance, off the top of my head, Section 1 is for most normal user commands. Section 3 is for programming languages, Section 5 is for file formats (e.g., /etc/fstab), Section 8 is for games. I used to know all the sections, but I can't find the info very quickly right now... :(
