I installed lnav from AUR. In fact I tried both lnav and lnav-git. The default command
lnav
does not do anything, but it is supposed to return syslog logs. It works on Ubuntu. So, I am thinking because syslog is not available on arch by default anymore. Am I correct?
The solution has been to use the following command:
journalctl -o json | lnav
But it took a long time of scrolling to get to the end of the log. Does anybody have any idea how to see journalctl logs in lnav without the long wait?
