OK where do i see them?

So what is the script you posted?
Now even this script puzzles me as I cant see how it works...
Do you mind explaining what this first line is supposed to do?
Code:
echo "exit" | user/password | grep Connected > /dev/null

Then
lets say the following works:
Code:
if [ $? -eq 0 ]
then
   echo "Passed"
   while read file

Where is file set? ...
Hi vbe,
Code:
   while read file
   do
   echo "Executing file $file..."
   output=`user/password << EOF >> test.log
   @/home/$file`
   done < /home/master.sql

Each time through this loop, the variable named file is set by the read command to contain the contents of a line read from the file /home/master.sql. (But, that would only be true if the here-document inside that while read loop was terminated. Oh, well.)

Having said that, I agree with you that I have no idea why finding the string Connected in the output from the utility named user/passwd when it reads a line from standard input that is exit would provide any reason for reading names of files from a file named /home/master.sql.

And, since the here-document terminator (i.e., EOF) does not appear anywhere in the code provided in post #1, this script can't possibly be working. I'm afraid preethi87 has failed to tell us several things that are important before we will be able to help debug the problem that was specified.
