NAME

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

DESCRIPTION

17       dar_cp is similar to the standard 'cp' command, except it does not stop
18       copying  when  an I/O error is met. Instead, it skips a bit further and
19       continues to copy the rest of the file, as much  as  possible,  filling
20       the gaps by zeroed bytes.

22
23       dar_cp only accepts full filename (not directory) as argument. The rea‐
24       son of its existence in dar package is that you  need  it  if  you  use
25       Parchive  with  dar  and have a corruption on a CD-R or any other read-
26       only medium. You need to copy  the  corrupted  slice  on  a  read-write
27       filesystem,  for  Parchive  be able to repair it using slice associated
28       redundancy files.
