Hello,
I found some information online about the ‘lnav’ (Log File Navigator) tool, a powerful log viewer for the terminal that can do far more than ‘tail’, ‘less’ or ‘grep’.
Installation:
sudo apt update
sudo apt install lnav
A few commands:
lnav # load the default system log (/var/log/syslog)
lnav /var/log/ # loads all log files in /var/log/
journalctl -f | lnav # real-time stream of the systemd log
lnav /var/log/dmesg # opens the kernel ring buffer from the last boot
lnav /var/log/kern.log # opens the kernel log with colour coding
sudo lnav /var/log/boot.log # opens the system boot log
To search for a word in lnav, press ‘ / ’ and enter for example the word Error.
? is for help
