Hi,
I have a string conatining hex digits like this:
hexdig="b05a02d7d1df3e6993eca90fa00241550dc95ec8e22d9b7194e2549cbd2f0ee37ec802d358d7447e0d78568d6f927ca4695173979e0f46573073cc8a785ac181"
and I have an Array like this
arr=( T h i s i s a n e x a m p l e ! ) # Could be any othe contents!
Now I want to step through hexdig digit by digit and use every single
digit as an index into arr by interpreting each digit as hexadecimal
digit.
Unfortunately I haven't any succes in doing so...
Thank you very much for any help in advance !
Best regards,
mcc

% for i in ${(s::)hexdig}; do echo -n $arr[$(( 16#$i + 1 ))]; done; echo

[...]
echo ${hexdig//(#m)?/$arr[1+16#$MATCH]}
also works with:
arr="Thisisanexample!"
