[SOLVED] Centos 7 Man Page subsection definitions?

bodisha · 02-11-2018, 09:08 AM

Hello... And thanks in advance for any help anyone can offer me

Can anyone point me to a list of definitions of all the Centos 7 man page subsections? I can't find a simple easy list to look at... I can sort of figure out when some of them are (p = posix)... But I was hoping to find a simple quick easy list that explains them all

(0p)
(1)
(1m)
(1p)
(1ssl)
(2)
(3)
(3p)
(3pm)
(4)
(5)
(5ssl)
(6)
(7)
(7ssl)
(7stap)
(8)

Once again... thanks for any help anyone can offer

A man page is a man page, their not specific to CentOS (or any other distro), AFAIK. There maybe **some** things that either do or don't apply to Linux, may instead only apply to say FreeBSD for example - or any other *BSD/UNIX system. The other form of that sort of documentation in Linux, would be the Texinfo pages.

See "Manual sections" to see what the sections mean: https://en.wikipedia.org/wiki/Man_page

Thanks for the reply! Initially I looked at the wikipedia man pages... But the wiki page doesn't explicitly talk about the subsections. I searched Google for about an hour but couldn't find anything specifically outlining the man pages subsection topics... and what the wikipedia page does say... doesn't necessarily align with what I'm seeing about the commands in those subsections

For example... the wikipedia page only referenced the use of a 1M subsection under Unix System V... And seems to state the use of this is for "System administration commands and daemons"... But of the 5 commands that appear in the 1m subgroup... None of them qualify as sys admin commands or deamons

With all this in mind I'm hoping someone can offer more detail than a Wiki page... Once again though... Thanks for the assistance

Yes, the "p" means "posix" and "n" means "new" man pages.

The following links may explain more:

It looks to me like "5ssl" refers to OpenSSL's configuration file.

From http://man7.org/linux/man-pages/man7...lenames.7.html

Quote:

config.5ssl
OpenSSL CONF library configuration files from section 5 with
group ssl.
