One of the big advantage of --grep compared to |grep is that it
returns the whole message, not just the line containig your regex<br>
<br>
so you can combine it with "-o verbose" and get all the info on the
message easily<br>

<pre wrap="">There are a lot of ways you can select the output you get from
journalctl, but it seems you cannot select on the message itself.
That is why I need to do something like:
journalctl | grep 'Database is locked'
Is this true, or am I overlooking something?

Since version 237, journalctl has had a --grep option.
Message text is not indexed, so performance-wise this still requires
going through all messages (as limited by other options).
