|DAR_CP(1)||General Commands Manual||DAR_CP(1)|
dar_cp - 'cp' clone command that is able to copy data located after an I/O error
dar_cp <source file> <destination file>
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.
dar_cp exists with the following codes:
- upon normal execution (be some corrupted parted skipped or not)
- syntax error on command-line
- 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
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
