Add -H option for extra security without root (Thanks to intika https://github.com/intika). It protects against dumping, code injection, cat /proc/pid/cmdline, ptrace, etc.. (only works with Bourne shell (sh) scripts with no parameter)
Add -s option to force single process for hardening features (requires -H) https://github.com/intika. (only works with Bourne shell (sh) scripts with no parameter)
