I'm running some additional scripts on my picoreplayer instances to pull
data from some bluetooth based sensors. This script requires pcre
support in grep.
My older picoreplayer 7.0 systems still work as they currently have grep
3.1
Code:
--------------------
tc@bluesqueeze:~$ grep --version
grep (GNU grep) 3.1

tc@bluesqueeze:~$ grep -oP 'value: \K.*'
--------------------
On my recently upgraded instance I tried installing grep from extensions
and it now lacks pcre support
Code:
--------------------
tc@Homeoffice:~$ grep --version
grep (GNU grep) 3.4

tc@Homeoffice:~$ grep -oP 'value: \K.*'
grep: Perl matching not supported in a --disable-perl-regexp build
--------------------
Has anyone else hit this issue, and do you have a recommended fix as I'd
like to upgrade my pizero environment to version 8.0.
