This is a simple utility for rapidly converting decimal numbers (base10) to
their hexadecimal (base16) representation. By default the command adds a newline
to the output, and this can be omitted by providing the -n flag.
If you'd like to convert from hexadecimal to decimal, either create a copy of
the binary named h2d or symlink it:
ln -sf ./dec2hex ./h2d
I personally have two symlinks: d2h for a short-handed dec2hex, and h2d for
a short-handed hex2dec.
