archives, file timestamps and touch

digitalgravy · 02-24-2005, 09:47 AM

I have a website and I want to modify some page elements but then restore the last modified time to what it was before I updated the file.

At the bottom of my pages I use php to read the last modified time of the document and print it to the page.

I have articles and other stuff that I do not want the time stamp to change, but I need to tweak the contents of the <head>. So nothing on the page is changing, just some meta tags.

The closest way I have found to do this would be to tar the whole site, make my changes, then read the time stamps from the files in the tar file, then use touch -mt to change the time stamps back.

How do I get the last modified timestamps from with in the tar file?
And can I have the timestamps outputted to a file with the time-stamp and the path?
Then How do I pipe that info to touch?

Is this possible?

What a headache, I'm going to do this kind of stuff with includes from now on so I don't need to worry about this again.

Any help would be appreciated.

Before you mod things:

Code:

find -printf "%p %CY%Cm%Cd%CH%CM.%CS\n" > times.txt

Afterwards:

Code:

cat times.txt|while read  file stamp; do touch -m -t$stamp $file; done

Cheers,
Tink

I had been getting mixed results with this. Some of the times were showing up incorrect. I use this technique once in a while. Well what is happening is the original command specified %C which returns the last Status Change. I need it to show the last modification time. For this you use %T.

Code:

find -printf "%p %TY%Tm%Td%TH%TM.%TS\n" > times.txt

This returns exactly what I want.

Thanks Tinkster, you got me in the right direction!
