Okay I'm trying to look up a man page on a mac pro running 10.7.4.

man 3 time

and get...

no entry for time in section 3 of the manual

I tried this on another mac running 10.6.8 and it works fine. Do I need to do something to get this working on 10.7??? Don't understand why it is not available on my new system.

It works for me. What do you get as the results of "echo $MANPATH"

I get no results, just a prompt.
What should be the result?

Really, it depends on how you set your MANPATH, but my computer running 10.6.8 shows:

Code:

% echo $MANPATH
/sw/share/man:/usr/share/man:/usr/bin/man:/usr/local/man:/usr/local/share/man:/usr/X11/man:/usr/man

Looks like there's no section 3 in the man for the time command in Lion.

Has it been replaced by the date command in Lion?

Looks like many manuals have been changed in Lion, eh?

jsalmi · 07-09-2012, 05:04 PM

It works for me as well on 10.7.4.

Keep in mind section 3 of time talks about the libc function time(), not about the command time. The latter is in section 1.

Also keep in mind time is also a shell build-in.

Now I think on it a bit, I seem to remember that MANPATH may be deprecated in OS X. Ah yes, here it:
http://hints.macworld.com/article.ph...31014053111192

It's dynamically constructed from PATH. From days of yore, I still have it set it in my .profile. I might comment it out.

So, what do you get as the results of "echo $PATH"?

I also seem to remember that there was an issue with Leopard upgrades from Tiger, where a lot of old Tiger man files were not deleted, leading to old man pages being used. But I digress.

svalenti · 07-10-2012, 07:59 AM

When I run this code I get...

Steven001737:~ svalenti$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

running manpath returns nothing...
Steven001737:~ svalenti$ echo $MANPATH

Steven001737:~ svalenti$

If these pages are missing how do I install them???

svalenti · 07-10-2012, 08:06 AM

I should add that this is a new mac that came with 10.7 so I didn't upgrade from a different lower OS.

benwiggy · 07-10-2012, 09:33 AM

It's much more likely that the man pages are installed, but not being found.

Reading further, it seems that if the $MANPATH variable is set, then those paths are used. If it isn't, then the paths are derived from the /etc/man.config file. However, it's not clear if that includes everything or everywhere by default. You may want to uncomment the following lines:

Code:

# Uncomment if you want to include one of these by default
#
# MANPATH	/opt/*/man
# MANPATH	/usr/lib/*/man
# MANPATH	/usr/share/*/man
# MANPATH	/usr/kerberos/man

Comparing my two macs I see I only have 3 files in use/share/man/man3 folder on the machine that doesn't display the man pages running 10.7 where as there are lots of files on the other mac running 10.6 and contains many files beginning with Time....

Here are the only files in mac running 10.7...
Guard_Malloc.3.gz
guardmalloc.3.gz
libgmalloc.3.gz

If I do man 3 libgmalloc I get that page....

Where should the man pages for section 3 reside????

benwiggy · 07-10-2012, 02:30 PM

Interestingly, "man 3 time" doesn't work on my 2009 MacBook.
It doesn't have a man 3 folder in /usr/share/man. (man 1, man 4 to man 9.)

Might the difference be an Xcode installation?

svalenti · 07-10-2012, 03:21 PM

I have Xcode installed on both. The 10.7 mac was install thru the app store. I didn't have a choice where or how to install it... It just does whatever....

ganbustein · 07-11-2012, 03:10 AM

I wonder if this is part of what Xcode considers "command line tools". Many files that are only useful to a programmer are not installed with OS X by default. The Xcode installer installs many of them (like the compilers themselves, and the header files in /System/Library/Frameworks). Then Xcode itself asks whether you want to "install the command line tools", which you would want it to do if you want to do any of your development outside the Xcode walled garden.

The man 3 pages would seem to fit that description. If you're writing a call to time(3) from within Xcode, Xcode can tell you all about it by consulting its private help files. You only need the files in /usr/share/man/man3 if you're programming outside Xcode.

I can't tell. I have Xcode installed on all my bootable volumes.

Look in Xcode→Preferences...→Downloads→Components and see if "Command Line Tools" is marked "Installed". Click (Install) if it isn't.

svalenti · 07-11-2012, 03:34 PM

That was exactly it!!! Installed the command line tools and the /usr/share/man/man3/ folder was populated with files. I now have access to the documents in terminal app.

Thanks!!!
