Dear all,
"journalctrl -b" shows messages from the current boot.
However, I often find it useful to look at messages from the previous boot.
Hence I would like to propose a new feature:
"journalctrl -b <n>"
should show messages from the n'th previous boot,
default being n=0, i.e. current boot.
What do you think about this?
Sounds like a good idea. Added this to the TODO list.
Great! Thank you.
PS:
It might also be useful to have an option to show all boot-ID's in
the journal,
maybe showing first and last timestamp of the log, and number of entries.
And maybe having an option like "journalctrl -b <boot-ID>"
Yes, it is actually our plan to implement work-alikes for "last",
"lastlog" and suchlike to systemd that simply take the data out of the
journal for that. A similar tool could be one that inspects boot IDs
like you suggest. To make this work nicely we need a minor update of the
journal indexing logic however (which is already there in the format,
but not implemented)
