Request to migrate to grep -E

[PolarianDev]

Hello,

I seem to remember it being mentioned that no migration to grep -E will be made because it would break backwards compatibility, however I can't seem to find this thread now. In case I was wrong, I am making this issue.

Could you migrate to grep -E as GNU's grep implementation will drop egrep as its deprecated in the following versions, and acme.sh is likely to no longer work on such systems.

Linked issue: #4835
Linked commit with comments: fe890c6
Potential solution: fe890c6#commitcomment-134504860

Thank you,
Polarian

Please upgrade to the latest code and try again first. Maybe it's already fixed. acme.sh --upgrade If it's still not working, please provide the log with --debug 2, otherwise, nobody can help you.

GNU grep implementation will drop egrep

That will never happen ;-)

The warning is printed to stderr and it's safe to just eat it so that was made in the fe890c6.
Wait for the next release.
