Before this update all remote commands were bunched together and
sent to the remote host in a single SSH command. This could result
in a very long sequence of commands that might be rejected by a
remote host (example is VMware ESXi that uses busybox sh).
With this update you can set DEPLOY_SSH_BATCH_MODE="no" and
each remote command is sent as a separate SSH call so now we
do not have big long sequence of commands. Defaults to same
behaviour as before this update.
_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.
