Question

linux

I have a configuration file file.cfg how to call the chmod +x bin/php7/bin/php command from it

Answer 1

What nonsense.
How do you want to call a shell command from the configuration file of an incomprehensible program?
Either specify what you mean at all, or not at all.

Answer 2

in the terminal, read/grab the desired line/parameter from .cfg and execute
bash -c $(grep 'part of your command' your.cfg)
