The first $ command is your own shell script to compress the folder of the second parameter to the path of the third file. Let's talk about the current situation.
1. php. ini has no security mode enabled. you can call commands such as ls normally.
2 system returns 126 when executing this command, and the second exec parameter is null.
3. the html directory 777 permission is granted to the generated file, and the compressed test directory is also the 777 permission.
4. run this command using the command line.

Is there any configuration required to execute such a custom script ??

The execution was finally blocked by selinux, leaving a result for your reference. The result is that the script can be executed normally in php-cli mode, and 126 is returned by executing the script on the webpage with sudo and 1 is returned.
