aus https://unix.stackexchange.com/questions/1810…session-dmesg-0
Options:
- -k (dmesg)
- -b < boot_number > (How many reboots ago 0, -1, -2, etc.)
- -o short-precise (dmesg -T)
- -p priority Filter by priority output (4 to filter out notice and info).
NOTE: there is also an -o short and -o short-iso which gives you the date only, and the date-time in iso format respectively.
Commands:
- All boot cycles :
journalctl -o short-precise -k -b all - Current boot :
journalctl -o short-precise -k - Last boot :
journalctl -o short-precise -k -b -1 - Two boots prior :
journalctl -o short-precise -k -b -2 - And so on
sieht dann z.B so aus
