dar_cp (1)

dar_cp <source file> <destination file>

dar_cp -h

dar_cp -V

dar_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.

dar_cp 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.

-h

Displays help usage.

-V

Displays version information.

dar_cp exists with the following codes:

0

upon normal execution (be some corrupted parted skipped or not)

1

syntax error on command-line

2

could not open source or destination files

3

any other system error met during the copy

5

when some data could not be copied due to I/O error

Any 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

dar(1), dar_xform(1), dar_manager(1), dar_slave(1)

None actually.
