shc:tldr:c8ee5

The command "shc -f ${script}" is used to encrypt a shell script file.

Explanation:

• "shc" is a utility that stands for "Shell Compiler". It is used for encrypting shell scripts to protect their source code and prevent unauthorized access.
• "-f" is an option followed by a parameter. It specifies the file that needs to be encrypted. In this case, "${script}" is a variable representing the name or path of the shell script file.
• The command encrypts the specified script file using shc and produces an encrypted binary executable file.
• The encrypted binary file can then be executed like a regular shell script, but the original source code is not directly visible, providing some level of protection.

Note: The command assumes that the "shc" utility is installed on the system. If it is not installed, you may need to install it first.
