Convert decimal to hexadecimal in UNIX shell script

Question

In a UNIX shell script, what can I use to convert decimal numbers into hexadecimal? I thought od would do the trick, but it\'s not realizing I\'m feeding it ASCII represent

Answer 1

In zsh you can do this sort of thing:

% typeset -i 16 y
% print $(( [#8] x = 32, y = 32 ))
8#40
% print $x $y
8#40 16#20
% setopt c_bases
% print $y
0x20

Example taken from zsh docs page about Arithmetic Evaluation.

I believe Bash has similar capabilities.
