I'm wondering is there's a command or utility already built within the terminal that can take a little endian memory address (for e.g. 5F4A358F) and convert it into a hex code (in this case \x8f\x35\x4a\x5f)?

    A tool named xxd is often provided in a vim package. Write a script utilizing that to do your work. – iBug Apr 7 '17 at 13:09
  • @iBug Awesome tip, thanks. Started to do this in awk but I'll look at that also. – Michael A Apr 7 '17 at 13:23

perl -le 'print scalar reverse unpack "h*", pack "H*", "5F4A358F"'

First pack the hex string and then unpack it with 'h', essentially effecting the endianness change.
