Here we’ll use the -i (ignore) option to search for a specific string or patterns or message by scanning through the dmesg output but this option will ignore the case of the strings and will focus only on the string we search for. The last 10 messages are displayed using the tail option $ sudo dmesg | tail -10 Here we check for the first 10 messages using the head option $ sudo dmesg | head -10 To monitor real-time logs –follow option is used with dmesg, and it displays the recent messages at the bottom of the terminal $ sudo dmesg -followĪs we see that dmesg gives out large output, we can use the tail or head option to list out a specific number of messages and view them. In this option, the resolution is lowered by a minute $ sudo dmesg -T We use -T (human-readable) option as they display with standard date and time. Messages taking place every minute are marked as seconds and nanoseconds. In the timestamp, it shows the date and time.
$ sudo dmesg -Lĭmesg uses timestamps in seconds and nanoseconds, for human-friendly format use the “H” option for timestamps. To search for a specific log or term of your choice with the help of forward slash “/” to search within less $ sudo dmesg | lessĭmesg gives coloured output by default as shown above but if you want to colourize it for proper understanding of the messages then you can colourize them using the “L” command. While we use the dmesg command it gives large output, we can use tail, head or less command to view the logs page wise.
