What version of bash are you using? Bashfuscator needs 4.0+ to work properly I believe
bash --version GNU bash, version 4.4.19(1)-release (x86_64-pc-linux-gnu)

I love the idea and there are some neat tricks in Bashfuscator. Once it gets stable and is widely useable it would be a great addition to the cheat sheet.

I agree, this is an interesting idea but unfortunately don't work on real bash scripts with medium level of complexity. Also, script arguments seems to wont work either :
Original
./rmqStat.sh -h [ Graylog Stack ] RabbitMQ cluster queue monitor. Usage: rmqStat.sh
Options are:
-h,--help Print this help screen.
Obfuscated
./rmqStats-ob.sh -h ./rmqStats-ob.sh: line 2: -h: bad substitution
I thought it was nice until I found the same issue. Even with a quite newish bash (e.g. CentOS 8), most scripts are useless when obfuscated by bashfuscator.
Found shc
(which is also readily available from EPEL repository) to be more reliable and working fine.
The only downside to it is that it would make the obfuscated script arch-dependent (e.g. x86_64).
Love the idea but it does not seem to be reliable. Tested on a few scripts and 50% just wont work.
Here is a simple script that wont work (example):
john@hax-vm:~/research/Bashfuscator$ cat script.sh
! /bin/bash
echo hello for x in
seq 1 10
; do echo test $x; done datej@hax-vm:~/research/Bashfuscator$ bashfuscator -f script.sh -o script-mutated.sh &>/dev/null j@hax-vm:~/research/Bashfuscator$ chmod 700 script-mutated.sh j@hax-vm:~/research/Bashfuscator$ ./script-mutated.sh ./script-mutated.sh: line 6: "${@/pD.H/s:C?$`Q9}" ${@/K\C~6} ; ${/+.q1f\/(yTSw} p"r"i${,}ntf %s "${tCzgy~~}" ${@##emo6Vrs|} "${@%%L~Zrw\"t}" $@ )" ${^} ${*%%_U{$Vmvk}
