Please let me know, how to solve the issue of extra comma on the end of the loop.

problem is
I have listed files in directory using ls *.txt|tr '\n' ','
to get abc.txt, def.txt,xyz.txt,

Each file name is passed as a parameter to the job.

After processing xyz.txt, loop tries to read the next value as there is comma after it and as there is none my sequence fails.

I also tried ls -m *.txt which gives me output as abc.txt, def.txt, xyz.txt which doesn't help in my case because my input to the
job will be /source/data/ abc.txt

As there is a space after data/ my command fails.

Ant insight would be great. Thanks.

Why not use a Nested Condition within the loop to verify that the $Counter activity variable is not empty?

If you have an "extra" character at the end of a string, simply trim it. You can substring out one less than the length of the string or do the same with the Left() function. For the "ls -m" approach, I don't recall ever seeing it add an extra space in the delimited list, what UNIX are you running?
