[systemd-devel] Make journalctl start at the end of the journal by default
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.

Re: [systemd-devel] Make journalctl start at the end of the journal by default
Hi, Seems the patch has been scrubbed. Will re-send it later if there is interest to have it. Should have used git send-email I guess, but now badly inlined at the bottom of this email. Thank you for your help, but you seem to have misunderstood what I am after.

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. There is the --reverse or -r option to show the newest entries first, is this what you are looking for ? No. I want -e as default option, as that is what makes sense to me. And I keep hearing the same from lots of people that -e should be default.

I can't think of any reason to have truncated and mangled logs by default. As it too often happens that you forget to add the flag as I just explained, you end up to have do all the searching again due to the interesting bit of the log being cut/truncated. The issue is having to use all those switches. Mainly I get sick of having to type journalctl --no-pager -a -e on a virtual keyboard every time on a development platform that gets reflashed continuously so having aliases etc is not really a workable option. And well and the pager I do sometimes want it and other times I don't. Depends on what I want to do. As I stated I am willing to send patches to fix journalctl default behaviour to match common use cases. I know about the switches. My point is that you should not need to remember every time to use some switches to get default usable behaviour from journalctl when performing a simple basic operation.

I mean, I think having arrow keys is the common case. Not having them is the rare exception... It's not only whether keys are available but also terminal size. Personally I find default (lack of) line wrapping quite annoying - I'm still have to use small notebook with relatively tiny terminal size and default behavior means permanent scrolling right and left to see message itself and its timestamp (or origin) etc. I think line wrapping by default is really more user friendly - with small terminal it allows you to use whole message at once and with large terminal most lines probably fit in the width anyway so there will be no difference. ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
