Use dictionary word anywhere in the mask

[badagaga]

If I use the following command:

Code:

./hashcat-4.0.1/hashcat64.bin --stdout -a 0 -m 11500 hash.txt wordlist.txt -r apppend.rule -r prepend.rule

I get the following result:

Code:

Cannot convert rule for use on OpenCL device in file apppend.rule on line 1: $?a
Cannot convert rule for use on OpenCL device in file prepend.rule on line 1: ^?a
No valid rules left.

Am I missing something?
