'cp' command with a wget-like progress bar

Can not help re-posting: a tip and trick to make 'cp' command have a wget-like progress bar.

#!/bin/sh
cp_p()
{
   strace -q -ewrite cp -- "${1}" "${2}" 2>&1 \
      | awk '{
        count += $NF
            if (count % 10 == 0) {
               percent = count / total_size * 100
               printf "%3d%% [", percent
               for (i=0;i<=percent;i++)
                  printf "="
               printf ">"
               for (i=percent;i<100;i++)
                  printf " "
               printf "]\r"
            }
         }
         END { print "" }' total_size=$(stat -c '%s' "${1}") count=0
}

% cp_p /mnt/raid/pub/iso/debian/debian-2.2r4potato-i386-netinst.iso /dev/null
