Sounds like a pretty simple simple python script: ------------------------------------------------------- #!/bin/env python def spew(source_file_name, output_file_names, block_size = 8*1024): source = file(source_file_name, "rb") output_files = [file(s, "wb") for s in output_file_names] s = source.read(block_size) while s: for outfile in output_files: outfile.write(s) s = source.read(block_size) for outfile in output_files: outfile.close() source.close() if __name__ == '__main__': from sys import argv if len(argv) > 2: spew(argv[1], argv[2:]) else: #print some usage/help print "%s source_file dest_file1 [dest_file2 [dest_file3 [...]]]" % argv[0] ------------------------------------------------------- Just call it with bash> cd /mnt bash> python spew.py file1.txt usb1/file1.txt usb2/file2.txt for as many destinations as you want. Adjust the blocksize as you see fit: spew(argv[1], argv[2:], 1024*1024) or whatever your favorite blocksize is. It's not terribly graceful about error-checking, or prompting if any of the files exist previously, or if it can't write to any of the output files because for any reason (full disk, write-protected disk, destination path doesn't exist, etc). Thus, if there's a problem, you'll get a pretty backtrace that will allow you to solve all your problems ;) -tkc -- http://mail.python.org/mailman/listinfo/python-list
