I want to perform bc command on this output in order to get the sum of them.



Command:

    Maybe bc is not installed, so you must install it. Try sudo apt install bc

With bc



Install bc,



sudo apt update
sudo apt install bc


Now you can pipe to bc according to @steeldriver's comment,



$ stat --format=%s /etc/*.conf | paste -sd "+" - | bc
112126


Without bc



You can also let the bash shell calculate the sum $(( ... )) of the output of the command,



$ echo $(( $(stat --format=%s /etc/*.conf | paste -sd "+" - ) ))
112126


Please notice that I show the result in my Lubuntu system, your result will probably be different.
