Using "shc" to hide shell-script contents.

shc creates static binaries from shell scripts.

There is rarely performance gain from this, is most often used as another layer of abstraction for security through obscurity.

Example:

shc -e '12/31/2020' -m 'Contact Your Administrator' -rTv -f ./potd-ifadmin.sh
This will create:
./potd-ifadmin.sh.x
./potd-ifadmin.sh.x.c
      
For most cases, the ".sh.x" file is what you want to distribute.
