I need to access array which is dynamically created.

First look into the code:

ssh username@11.22.333.44 <<'ENDSSH'
cd /home/ubuntu/user/someFolder
array=(`find . -name 'something*'`)
len=$#array[*]

i=0
while [ $i -lt $len ]; do
 let i++
done
echo "$array[*]" #here I can access array values
ENDSSH
#Just above i have exited from ssh & now I need to access array values but not getting.
echo "$array[*]" #here I'm unable to get array values
exit

So, My concern is to access array after ENDSSH.

Since you're comfortable using backticks and find to construct the array, you clearly aren't worried too much about serializing the data robustly (for example, whitespace in the output of find is going to be split into distinct element of the array, which may not be desired), so just do:

array=($( ssh username@11.22.333.44 sh -c "find . -name 'something*'"))

and build the array on the local host.

From one of your comments, it sounds as if what you're intending to do is to create a list of pathnames of files that you'd like to transfer from the remote system to the local machine using scp. The issue with this is that you passing pathnames back and forth between the two systems which introduces the risk that filenames that includes whitespace characters may be mangled.

If you're looking for a way to transfer all the files that matches something* from somewhere under /home/ubuntu/user/someFolder on the remote machine, you may use rsync like this:

rsync -av --include='*/' --include='something*' --exclude='*' 
 --prune-empty-dirs 
 username@11.22.333.44:/home/ubuntu/user/someFolder/ ./target

This would find and transfer all files matching the pattern and the directory structure that they live in to the local machine under the path ./target.

The --include and --exclude patterns are applied from left to right and the first match is what matters:

• 
  --include='*/': Look into all subdirectories (empty directories, i.e. directories with no matching filenames, are not transferred due to --prune-empty-dirs).


• 
  --include='something*': The pattern that would match the things we're actually interested in.


• 
  --exclude='*': Ignore everything else.
