You need to have a recent util-linux for most of these. If you're on Ubuntu, you probably have 2.20.
From the release notes:
2.20: supports new command line options: --clear, --console-on, --console-off, --ctime, --decode, --facility=<list>, --level=<list>, --show-delta, --notime, --kernel and --userspace
2.21: supports new command line options --file to read the log from a file rather than from kernel buffer
2.22:
- reads kernel messages from /dev/kmsg on kernel 3.5
- supports new option --follow to wait for new messages (kernel 3.5 required)
- supports new option --reltime to print human readable deltas
2.23: supports new command line options --color, --human and --nopager, the --human option enables relative times, colors and pager support.
- voltagex_ 13y agoI wonder (other than the features requiring kernel 3.5) what dependencies dmesg has - could I just carry a static binary around in my ~/bin for systems that don't have a new util-linux?
- wereHamster 13y agoCheck for yourself with `ldd <path/to/dmesg>`
