My shell is bash and I need to write a script that runs a specific software for each input data in the several folders. For example:

gd2p.pl -i /home/WORKDIR/folder1/input1.o

Let's say that I have 20 folders in WORKDIR and each folder includes input files. How can I write the script which run the above codes for each folder and each input files automatically?

You can try this code.

for file in */*; do           # Loop trough any file in any folder
    if [ -f "$file" ]; then   # If the current element is a file
        gd2p.pl -i "$file"    # Run the program
    fi                        # End if
done                          # End loop

My solution would be to use find:

find /home/WORKDIR/ -name "input*.o" -exec gd2p.pl -i {} \;

That gives you (virtually) unlimited depth in sub-folder structure.
