rename command in my system -Fuduntu running 2.6.38 Linux Kernel- is an ELF 64-bit LSB executable, not a Perl script. man page for rename command shows syntax as "rename from to where" (or something like that), so I am doing just what I have been told...
echo "ls" > script.bash;
This is my script, a simple 'ls'.
gpg -c script.bash;

Here I open file script.bash.gpg, decrypt it and execute it.
