##Shell 80 ###tools: bc -l, tr, dd

echo "scale=2468;obase=16;4*a(1)"|bc -l|tr -d '\\\n'|dd bs=1 skip=1026 count=1K

###Shell 64, tools: bc -l, tr, tail, differs in the rounding of the last place

echo "scale=2466;obase=16;4*a(1)"|bc -l|tr -d '\\\n'|tail -c1024

Might be considered cheating, since the knowledge how to compute PI is in 4*a(1), and that 1 have to use scale=2466 was iteratively investigated.

Thanks to breadbox for the idea to use tail -c1024 instead of dd bs=1 skip=1024 (skip=1K would have been a less useful option to improve it).

##Shell 68 ###tools: bc -l, tr, cut

echo "scale=2468;obase=16;4*a(1)"|bc -l|tr -d '\\\n'|cut -c1027-2051

echo "scale=2466;obase=16;4*a(1)"|bc -l|tr -d '\\\n'|tail -c1024

Might be considered cheating, since the knowledge how to compute PI is in 4*a(1), and that 1 have to use scale=2466 was iteratively investigated.

Thanks to breadbox for the idea to use cut.
