Hello,

<excuses go here>

When I do a 'man regex', for instance, I find a line there saying:
See also regex(3)
I tried typing 'man regex3' (no manual) and 'man regex(3)' which generated a syntax error.

And I see tons of those references to commands with numbers in parentheses wherever I go.

What does that mean? Different versions of the same command/utility? How are they invoked, how do I get to their man/info pages?

Thanks,
Daniel.

Hi BlackHorseman,

Try the following command to confirm if there are any other man pages for regex:
$ ls /usr/share/man/man*/regex*

The output I get is:
/usr/share/man/man7/regex.7.gz

which indicates the man (7) is the only man page for regex.

In that case, all of the pertinent information for your Linux distro is in man (7), and the other See also man pages may not exist for your OS.

You can of course search for them on the Internet with: regex +manpage
to see what you can find that may have existed with earlier releases of either Unix or Linux.

Yeah, I get the same.
I think I understand, thanks.
