shc: Compile a shell script and set an expiration date for the executable.
$ shc -f ${script} -e ${dd-mm-yyyy}
try on your machine
The command shc -f ${script} -e ${dd-mm-yyyy}
is used to compile and encrypt a Shell script file (${script}) so that it can be executed without revealing its source code.
Here's what each part of the command does:
shc
: The command that invokes the shell script compiler.-f ${script}
: Specifies the input file to be compiled and encrypted.${script}
represents a variable that should be replaced with the actual path or filename of the script you want to compile and encrypt.-e ${dd-mm-yyyy}
: Specifies an expiration date for the compiled script.${dd-mm-yyyy}
represents a variable that should be replaced with a specific expiration date in the format DD-MM-YYYY. After this date, the compiled script will not execute.
By running this command, the specified Shell script will be compiled into a binary executable, making it more difficult for someone to modify or reverse-engineer the original script. Additionally, the encryption and expiration date provide an additional layer of protection to control the usage and access to the script.
