NAMEdar_cp - 'cp' clone command that is able to copy data located after an I/O error
SYNOPSISdar_cp <source file> <destination file> dar_cp -h dar_cp -V
DESCRIPTIONdar_cp is similar to the standard 'cp' command, except it does not stop copying when an I/O error is met. Instead, it skips a bit further and continues to copy the rest of the file, as much as possible, filling the gaps by zeroed bytes.
only accepts full filename (not directory) as argument. The reason of its
existence in dar package is that you need it if you use Parchive with dar
and have a corruption on a CD-R or any other read-only medium. You need to copy
the corrupted slice on a read-write filesystem, for Parchive be able to repair
it using slice associated redundancy files.

EXIT CODESdar_cp exists with the following codes:
- upon normal execution (be some corrupted parted skipped or not)

- could not open source or destination files
- any other system error met during the copy
when some data could not be copied due to I/O error
SIGNALSAny signal sent to dar_cp will abort the program immediately, there is no way to have a proper termination before the end of the process
