Joe Skora commented on NIFI-1817:
---------------------------------
[~devriesb] I would recommend using
{code}
grep -vE "^\W*#"
{code}
so that you eliminate lines where "#" is the first *non-whitespace* character.
It will save you frustration later if some values get indented accidentally or
intentionally.
> nifi.sh doesn't respect comments when setting run_as user

> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Brandon DeVries
> Assignee: Aldrin Piri
> Priority: Minor
>
> In nifi.sh\[1\], the run_as user is set using the following line:
> {code}
> run_as=$(grep run.as "${BOOTSTRAP_CONF}" | cut -d'=' -f2)
> {code}
> However, this does not respect a commented out "run.as" line in
> bootstrap.conf. To fix, we need to do something like:
> {code}
> run_as=$(grep run.as "${BOOTSTRAP_CONF}" | grep -v '^#' | cut -d'=' -f2)
> {code}
> That will disallow any lines that start with a "#".
