Code:
#!/bin/bash
cd /apps/sym/arcload/VSORT_X9/test
FILE_LIST=/apps/sym/arcload/VSORT_X9/SrcFiles/Source_input.txt
for file in *[_-]S[_-]*[_-]*[_-]*[_-][0-9][0-9][0-9][0-9][01][0-9][0-3][0-9][_-][0-2][0-9][0-6][0-9][0-6][0-9].txt
do      IFS='[_-]'
        set -- $file
        unset IFS
        echo "$file" >> $FILE_LIST
done

but here problem is its writing all files to the file list...i want to send first 4 grouped files do operation on that and same operation for next 2 grouped files and so on..

thanks for your help againSmilie
I do not understand what you are trying to do, so I don't see how I can help you.

You have removed all of the code that created groups of files, so I don't know what groups you are now talking about.

The code you have shown above could be replaced by the much simpler code:
Code:
#!/bin/bash
cd /apps/sym/arcload/VSORT_X9/test
FILE_LIST=/apps/sym/arcload/VSORT_X9/SrcFiles/Source_input.txt
printf '%s\n' > "$FILE_LIST"  *[_-]S[_-]*[_-]*[_-]*[_-][0-9][0-9][0-9][0-9][01][0-9][0-3][0-9][_-][0-2][0-9][0-6][0-9][0-6][0-9].txt

Please show us a brief list of filenames you want to process and then clearly explain how you decide which four files to process first, which two files to process next, and so on. And, clearly explain what operation you want to perform on each group of files.

Note that if the directories you created in your earlier problem are the groups you're talking about now, the list of files in your output file is not sorted into groups in any manner (and files that would have been grouped together in directories will not necessarily even be adjacent to each other in the output file produced by your code above).

More importantly, if you didn't understand the answers I provided in post #7 in this thread for your questions, please ask more questions. Our goal here is to help you learn how to write your own code. We are not here to act as your unpaid programming staff.
