echo -n “” | sha256sum -b | awk {‘printf $1’} | xxd -b -c 1 | awk {‘print $2’} | paste -sd “”
echo -n “” |
echo blank with no line feed ‘-n’ pipe out
sha256sum -b |
generate sha in binary ‘-b’ then pipe out
awk {‘printf $1’} |
awk $1 and printf to supress new LF then pipe out
xxd -b -c 4
xxd to turn into nice output
