I want to convert my shell scripts into binary executable so that nobody else could edit or read it. Is there a way to convert it into a binary executable?

shc is what you're looking for. get it here: shc
Extract, cd into dir, make and then ./shc -f SCRIPT. Done.

Everything you need to do this, you find here:

+1 wow, that is interesting. Just beware that if the process is exactly as it is described, this is a weak method of concealing a password -- it could still be extracted by someone who knows how executables are structured. However, it would be very effective for obscuring a script from casual observers. I'd be interested to learn if scripts pre-compiled this way are faster to execute. –  goldilocks Feb 14 '13 at 6:48
Note that it doesn't work with bash (or sh based on bash), as one can do: env SHELLOPTS=verbose ./script.x to see the content of the script. There's probably easy ways to bypass with other shells as well. –  Stéphane Chazelas Feb 14 '13 at 11:14
From the shc man page, "Unfortunatelly, it will not give you any speed improvement as a real C program would." datsi.fi.upm.es/~frosal/sources/shc.html –  Adam Feb 14 '13 at 19:35
