_egrep_o() function accepts extended regex and on systems that do not have egrep uses sed to emulate egrep.
This is failing on the specific regex I was using before my last commit... https://github.com/dkerr64/acme.sh/commit/ae66c6f0b484ce5c451ff8c195f382115b3d15a0
The problem is that I fixed it by passing in non-extended regex which then fails on systems that do have egrep. So I am no longer using _egrep_o.
We have a few domains that ends the same. For example :
iperfony.com
perfony.com
The problem was in the _get_root functions, when getting the domain_id :
only the first result "iperfony.com" was returned, because "perfony.com"
is contained in the "iperfony.com" string.
The correction consist of being strict in the regex, adding a slash (/)
so that it will only match on ".*/(perfony.com).*" and not
".*(perfony.com).*".
