dar_cp

DAR_CP(1)						      General Commands Manual							 DAR_CP(1)

NAME

       dar_cp - 'cp' clone that does not stop at the first I/O error met

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.

OPTIONS

       -h		   Displays help usage.

       -V		   Displays version information.

EXIT CODES

       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

SIGNALS

       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

SEE ALSO

KNOWN BUGS

       None actually.
