After the configuration, there are lots of files updated.
How to find the latest updated file in certain time range?
Like WinXP or Win2000, we might specify the time range to search.

Use find, it can probably do exactly what you want.

As b0uncer suggest, try find utility.

But I suggest use info find, instead of man find. Info manual contain more information, and also has a better structure.

In my own opinion info pages are more difficult to use (man only needs upwards/downwards scrolling, no "links", can search) and man pages hold all the relative information, I've never actually found anything from info that wasn't in man that I'd need. Shortly said, I think man is faster to use.

Of course it's everybody's own choice, but I think having both man- and info pages on disk is just a waste of disk space. And not all distributions even come with info pages, so it's a good thing to learn to use the manual pages the Unix way.

I think, info pages more complex, not more difficult. I agreed with you, that man pages faster, but I always use info, if I have that choice.

And, I using Emacs for all my works and even for my personal needs, so info is the best for me, as Emacs is the best info reader.

In my distro - Debian GNU Linux, man pages usually comes from package with program, in opposite, info pages comes from package with documentation for program. So it's impossible to remove man- or info-pages without removing its package.
And disk space is really cheap today.

Finally, I use man-pages very often, if program is simple, for reference about options and such things. But, find is rather complex utility, that's why I suggest using its info page.

P.S.: I remember, Mandrake Linux 6.0 had option for installing even without man-pages.
