Hello,

often I copy a lot of files. The kernel stores the blocks of the files in
its cache, but i know that these files fill not get accessed any more in
the near future. So i propose a new flag for the cp command to supress
caching the files.

Here i have a snippet of a code with which i sucessfully tested bypassing
the cache.


  FILE* fp;
  ...
  int filedescriptor = fileno (fp);
  posix_fadvise ( filedescriptor, 0, 0, POSIX_FADV_DONTNEED );
  ...
  fclose (fp);

Greetings
  Thorsten
