Ever hear of chmod? chown? Adam
The vendor also has superuser access.. chmod chown won't protect it.. :(
I once had to obfuscate an awk script. "Cryptography is Economics." My job was to make it difficult for the enemy to steal the source. There was a license agreement... The simple answer of "no" is right in the strong sense, but there are tricks to make life difficult for the amateur attacker. My approach was a self-decrypting program. The "real" script was encrypted within the body of the encasing script. For increased obfuscation, decrypt only small pieces at a time.
