Hex to Octal (3 digit) converer

[Philip Lord]

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!

Phil

Unfortunately I then need to manually add the missing ‘0’s, which can be a huge pain for long listings, and open to human error.
