dar_cp - disk archive copy
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.
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
