Thanks again, I?ve never used Perl either, but I
just installed it.
So I saved your script as a textfile called HEX_OCTAL.pl:
perl -n -e 'print join("
",map(sprintf("%03o",hex($_)),split(" ")))."\n";'
But unfortunately I get the following error when I try to run it:
syntax error at /Users/Philip/perl5/perlbrew/Perl_tests/HEX_OCTAL.pl line 1, near "n
-e "
Execution of /Users/Philip/perl5/perlbrew/Perl_tests/HEX_OCTAL.pl aborted due to
compilation errors.
Not sure what I?m doing wrong?being a noob, it could be anything!

There are two ways to resolve this.
First, you just put the command line I gave you into a shell script file (call it
conv.sh):
#!/bin/bash
perl -n -e 'print join("
",map(sprintf("%03o",hex($_)),split(" ")))."\n";'
Then just type './conv.sh' on the command line to run in interactive mode, or
'./conv.sh < test.dat' to source data from a file test.dat.
Or, second, to turn the perl one-liner into a real perl program, it needs to be this
(call it conv.pl):
#!/usr/bin/perl
while (<>) { print join("
",map(sprintf("%03o",hex($_)),split(" ")))."\n"; }
exit;
then you can run this in the same way as above, except type './conv.pl' or
'./conv.pl < test.dat'
