PHP Switch Selector

[giarosenko]

Hello everyone I am trying to install and set up CustomBuild on my DA.
I am new to all this, so if any question seems stupid don't judge, please.

I think i have installed the Custombuild and trying to figure out how I will be able to use as main php 5.6 & 7.2 second option for other websites that we host.

On instructions, i follow them but I think i am getting the error here.

[root@german ~]# echo "2.0" > /root/.custombuild

[root@german directadmin]# cd custombuild
[root@german custombuild]# echo "2.0" > /root/.custombuild
[root@german custombuild]# ./build rewrite_confs
