Find command doesn't pipe the output as required.

Is it stuck or does it come back with no result? Will any of the files exactly match an entry in the searchstring file?
# 9  
The execution gets stuck after first echo (which displays the string to be matched from the out file).
When the find command is executed on shell, it indeed returns the results (matching files) but this is not the case when I run via script. So, I concluded that find is the one creating a problem while piping output.

This is probably the difference between line buffering on the shell, and block buffering when the result is piped. To test the theory, just pipe the find through cat in the shell. It will probably hang for quite a while too. So either your find doesn't really terminate because it searches exhaustive nfs mounted volumes or just giving it some more time might help.
