ls * can list all the files in the subdirectories.
ls *.pdb can only list all the files with extension pdb in the current directory.
So how to list all the files with extension pdb in the subdirectories?
My subdirectories are named as 1, 2, 3, .... I would like the output also include the directory information, so that I can use the output as an ensemble of input files. For example, the output should be like:
1/a.pdb 1/b.pdb 1/c.pdb 2/a.pdb 2/b.pdb 2/c.pdb 3/a.pdb 3/b.pdb 3/c.pdb
