ddcopy.sh
#!/bin/bash
#
# The given script has been created for simplification of process of
# recursive copying of files and directories by means of utility
# Dataset definition dd.
#
# The author Dmitriy V. Mazitov 2009
# v. 1
#
# Usage order the following:
#
# ddcopy.sh /source_dir /destination_dir bs cf cdd rm
#
# Explanations:
#
# bs - a block size in mbytes (the Example: we enter number 50)
#
# cf - generation of a file of a script (the Example: we enter y or n)
#
# cdd - the consent to copying (the Example: we enter y or n)
#
# rm - removal of folders and files in a destination directory
# (the Example: we enter y or n)
#
# Example:
#
# ddcopy.sh /home/bob/films /home/share/video 50 y y n
#
# The file a script will be is in a home folder of the user from which
# name has been started ddcopy.sh
#
# It is possible to create a file a script for its studying and hand-held
# performance.
