Something like this perhaps:


Code:
#!/usr/bin/ksh
find /srcdir -type f | while read f
do
    destfile=$(echo $f | sed 's#/srcdir#/destdir#')
    if find $destfile -newer $f
    then
        print "$destfile is newer than $f, skipping"
    else
        print cp -p $f $destfile
    fi
done

Obviously take out the second print once you've confirmed that it's going to do what you want.

THANK YOU! this is where I have been trying to get to.
So I tried to convert it to using Bash Shell. (im on OS 10.5)

Here is my script:


Code:
#!/bin/bash
find /FolderA -type f | while read f
do
    destfile=$(echo "$f" | sed 's#/FolderA#/FolderB#')
    if find $destfile -newer $f
    then
        echo "$destfile is newer than $f, skipping"
    else
        echo cp -p $f $destfile
    fi
done

When i run it, it looks like it will do everything correctly. I threw some random files in and changed a couple to test. I am getting an error where I think it is stumbling on a directory name with a space in it. I tried puting quotes on things here and there but to no avail. here is the line form the output.


Code:
find: /FolderA/new: No such file or directory
cp -p /FolderA/new folder/CODES.txt /FolderB/new folder/CODES.txt

so it looks like it stumbles but then copies the file in the directory anyway.
Is there a way to help this spaced directory error?

do
    destfile=$(echo "$f" | sed 's#/srcdir#/destdir#')
    if find "$destfile" -newer "$f"
    then
        print "[$destfile] is newer than [$f], skipping"
    else
        print cp -p "$f" "$destfile"
    fi
done

I beleive it would be:

cp -p /FolderA/new\ folder/CODES.txt /FolderB/new\ folder/CODES.txt

will have to search for a space and add a \ then space.

Or just quote it at vgersh99 says on the next post.. :P

hmmm.... So it looked like it was going to work. I put those quotes in. I made an exact copy of the files in FolderA and put them in FolderB. (if the same everything should say it will copy) and I get this:

Code:
/FolderB/.DS_Store
/FolderB/.DS_Store is newer than /FolderA/.DS_Store, skipping
/FolderB/AnimalToysIcons/.DS_Store is newer than /FolderA/AnimalToysIcons/.DS_Store, skipping
/FolderB/AnimalToysIcons/Fasticon.com.url is newer than /FolderA/AnimalToysIcons/Fasticon.com.url, skipping
/FolderB/AnimalToysIcons/Icons/.DS_Store is newer than /FolderA/AnimalToysIcons/Icons/.DS_Store, skipping
/FolderB/AnimalToysIcons/Icons/Elephant is newer than /FolderA/AnimalToysIcons/Icons/Elephant, skipping
/FolderB/AnimalToysIcons/Icons/Giraffe is newer than /FolderA/AnimalToysIcons/Icons/Giraffe, skipping
/FolderB/AnimalToysIcons/Icons/Gorilla is newer than /FolderA/AnimalToysIcons/Icons/Gorilla, skipping
/FolderB/AnimalToysIcons/Icons/Lion is newer than /FolderA/AnimalToysIcons/Icons/Lion, skipping
/FolderB/AnimalToysIcons/Icons/Zebra is newer than /FolderA/AnimalToysIcons/Icons/Zebra, skipping
/FolderB/AnimalToysIcons/License - Read Me.url is newer than /FolderA/AnimalToysIcons/License - Read Me.url, skipping
/FolderB/C_PROJECTS/conversion.cpp is newer than /FolderA/C_PROJECTS/conversion.cpp, skipping
/FolderB/CODES.txt is newer than /FolderA/CODES.txt, skipping
/FolderB/new folder/CODES.txt is newer than /FolderA/new folder/CODES.txt, skipping

When you copy them it updates the timestamps, so all of the files will appear to be newer. Use cp -p to preserve the original timestamps when you create your test copy.
