DAR_CP(1)              DragonFly General Commands Manual             DAR_CP(1)


NAME

       dar_cp - 'cp' clone command that is able to copy data located after an
       I/O error


SYNOPSIS

       dar_cp <source file> <destination file>

       dar_cp -h

       dar_cp -V


DESCRIPTION

       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.

       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

       no way to have a proper termination before the end of the process
