bitcoin-qt bash script to make bootstrap.dat of all the blocks, and check that the client is shutdown, if that matters

mkbootstrap.sh

#! /bin/bash
echo $PWD
if ps aux | grep -q "[b]itcoin" ; then 
	echo "bitcoin is running, shut it down before running this script again"
	ps aux | grep "[b]itcoin"
	exit
fi

for i in blk*.dat
do
	sec="$(date +%S)"	
	echo $i ">>" "bootstrap.dat" $sec
	cat $i >> bootstrap.dat
done

as pointed out on IRC, this script does not create a exact duplica of the torrent data of jgarzik. This is because of stale blocks (not included because they waste space), zero-padding (block files are preallocated). The script does work and you can use the file it create, but its not a deterministic copy, meaning its unique to your client.
