Hi,
Having to often use journalctl it has slowly driven me insane with the
default options not matching common use cases.
Attached is already a patch to start the journal at the end. Usually
people check the logs when something went wrong, and don't care about
what happened three weeks ago at the beginning of the log. Yes you can
press the "end" key to skip to the end but in some cases that freezes up
the console for over a minute.
Other gripes are --no-pager... way too long to type on a virtual
keyboard when you are trying to use the logs old style with common unix
utilities. Maybe not having it by default, or introducing a shorter
command switch should not be hard to add.
And also I would like to see the full logs always by default. Usually
after lots of searching you find the offending log entry for the error,
only to find out you forgot to pass the right command line options to
journalctl and the important bit is cut off.
If you guys are willing to also consider those other two gripes I will
glady submit patches for those also.
Regards,
Philippe

Subject: [PATCH] journalctl : automatically go to the end of the log
Usually we do not care about the beginning of the log, as we want to look
at it when something went wrong. So usually this would be the end. So changing
the end feature into a start feature will cause less typing. (Also jumping to
the end of a log with the end key sometimes takes a considerable amount of time,
so we avoid that issue here too). To restore the old behaviour to start at the
beginning of the log, there is now -s or --pager-start. -e is kept for backwards
compatability.
