Recursively move directories along with files/specific files

I would like to transfer all files ending with .log from /tmp and to /tmp/archive (using find )
The directory structure looks like :-
Code:
/tmp
    a.log
    b.log
    c.log
         /abcd
             d.log
             e.log

When I tried the following command , it movies all the log files to /tmp/archive (does not maintain the directory structure )
Code:

find /tmp -name "*.log" -type f -exec mv {} /tmp/archive \; 

The output is

Code:
/tmp/archive
     a.log
     b.log
     c.log
     d.log
     e.log

whereas the output should be

Code:
/tmp/archive
     a.log
     b.log
     c.log
          /abcd
             d.log
             e.log

For copying (cp) ,this can be done using -R but does not work with move (mv) .Is there any simple command to achieve this .

I had gone through forums and come across few commands rsync ,tar ......

Code:
find /tmp -name "*.log" -type f -exec rsync {} /tmp/archive \;   /* gives the same output */

Also , could anyone explain the difference between cp and rsync
What is the usage of the command tar?

Try:
Code:
cd /tmp;find . -name "*.log" | xargs -i bash -c "echo {} | cpio -pdmu /tmp/arc; rm -f {}"

Bartus11,
could you please explain the code ?
# 4  
Bartus ,
I did understand the first part of the command
Could you also please explain the later part of the command ,
xargs -i bash -c "echo {} | cpio -pdmu /tmp/arc; rm -f {}" What is the usage of xargs , bash , cpio -pdmu

Is there any other suggestions ?
# 5  
First tell us if it worked in your case Smilie. xargs is passing the output from find as "{}". It is then used in bash command to execute two utilities: cpio and rm. cpio copies the file with its subdirectories if necessary (-d cpio option), while rm removes the original file after it has been copied.

What Operating System and version do you have?
Code:
uname -a

What Shell do you use?
Code:
echo $SHELL

On a design point, is this a one-off exercise or a job which will be run more than once? There are real scripting issues with your archive directory /tmp/archive being under /tmp .
Also on most unix systems /tmp is of limited size and considered volatile storage for files used by the Operating System. It is usual to create separate filesystems for application data and logs.
# 7  
Sorry Bartus , It didnt work

Here is one other example which I have tried

/* This is the structure for abcd*/

$ ls -R /usr/bin/abcd
/usr/bin/abcd:
efgh fff1.log fff2.log fff3.log

/usr/bin/abcd/efgh:
fff4.log fff5.log

/* I am creating another directory called abcd1*/

$ mkdir /usr/bin/abcd1

/* Using your command , I am moving the *.log files from abcd to abcd1 ,including the directory structure ( sub directories ). As you can see , it fails with the output below */

$ find /usr/bin/abcd -name "*.log" | xargs -i bash -c "echo {} | cpio -pdmu /usr/bin/abcd1 ; rm -f {} "

0 blocks
0 blocks
0 blocks
0 blocks
0 blocks

if xargs is for passing the output then what is the usage -exec {} .Is there any difference between these two
