v=$(date --date "-1 hour" +"-vY=%-y -vT=%-m -vD=%-d -vH=%-H -vM=%-M")

This builds a string with current time - 1 hour eg:
-vY=13 -vT=8 -vD=12 -vH=23 -vM=4

This is used as a command line...

Change last line to /^[[]/&&v' infile to avoid non-date lines following the first match.

I don't know why you are matching dates older than 1 hour, could you post the first line that matches...

Yes, tested with the format posted, some awk versions require a space between -F and parameter try (notice additional space here):

v=$(date --date "-1 hour" +"-vY=%-y -vT=%-m -vD=%-d -vH=%-H...

You could try this, assuming your date command supports --date :

v=$(date --date "-1 hour" +"-vY=%-y -vT=%-m -vD=%-d -vH=%-H -vM=%-M")
awk -F'[[ /:]' $v '
$4>Y ||
$4==Y&&$2>T ||
...

Does your date function support the --date=STRING option?

e.g.

$ date --date="date -d "2/5/12 10:50:12.148 EDT"
Sun, Feb 05, 2012 10:50:12 AM

The first problem with your code is you used single quotes: everything within single quotes is treated as is, not evaluated. This will probably work, but only find the entries with the current...

This may need some tweak to work for you
# Getting the data for last hour
data_1h=$(awk '$0>=from && $0<=to' from="$(date +"["%D" "%H:%M%S -d -1hour)" to="$(date +"["%D" "%H:%M%S )" logfile)
#...

We need the format of the log - a sample will be good.

Contradicting requirements.

And surprising that cp -R didn't work.
cp -R directory1/sub1 directory2/lib

Like this? This one-liner will find all files recursively under folder1/ and copy them into folder2/ without creating sub-folders.
find ./folder1/ -type f -exec cp {} ./folder2/ \;

If you have tar that supports -T option you could:

cd directory1
sed -e 's:^.*/::' -e 's/ .*//' /path/to/readme.txt | while read file
do
find ./ -name $file -print
done | tar -T - -cf - |...

Sorry missed \; on end of find statement:

sed -e 's:^.*/::' -e 's/ .*//' readme.txt | while read file
do
find directory1 -name $file -exec cp {} directory2/ \;
done

sed -e 's:^.*/::' -e 's/ .*//' readme.txt | while read file
do
find directory1 -name $file -exec cp {} directory2/
done

You could try this:

$1 is file1 $2 is file2
