Question on Initializing the Variable - UNIX for Dummies Questions & Answers

What i am trying to do is cd to my directory first. If any of that folder contains "volcano" folder then create the same directory structure in the remote machine "lexus". This is what i am doing.

Code:

LOCAL_LOG_FILE="logging.log"
DEST_DIR="/test/ferrari/testing"
cd /home/mike/
for dir in $DATA_DIR; do
   if [ -d ${dir}/"volcano" ]; then

   /usr/local/bin/ssh -l abc lexus "mkdir -p 777  $DEST_DIR/$dir" >>$LOCAL_LOG_FILE 2>&1
    scp -r ${dir}/"volcano" lexus:$DEST_DIR/${dir}/
    fi
    done

    exit 0

The code i posted works fine. It creates the appropriate directories as needed in the remote machine.

/test/ferrari/testing/joe/volcano/abc.txt
/test/ferrari/testing/mike/volcano/xyz.txt

But if i just put that "cd /home/mike" in a variable it creates the home directories also :-

Code:

   DATA_DIR="/home/mike/*"
   DEST_DIR="/test/ferrari/testing"

   for dir in $DATA_DIR; do
   if [ -d ${dir}/"volcano" ]; then

   /usr/local/bin/ssh -l abc lexus "mkdir -p 777  $DEST_DIR/$dir" >>$LOCAL_LOG_FILE 2>&1
    scp -r ${dir}/"volcano" lexus:$DEST_DIR/${dir}/
    fi
    done

    exit 0

The directory structure lookslike this on my remote machine:-

/test/ferrari/testing/home/mike/joe/volcano/abc.txt
/test/ferrari/testing/home/mike/joe/volcano/xyz.txt

Instead it should create :-

/test/ferrari/testing/joe/volcano/abc.txt
/test/ferrari/testing/mike/volcano/xyz.txt

Can someone tell me why this is happening?

if you look at how the for line will be expanded using the variable then you will understand.

Code:

for dir in /home/mike; do

I think it should be:

Code:

for dir in `ls $DATA_DIR`; do
