Automatic Log Format Detection

The log message format is automatically determined by lnav while scanning your files. The following formats are built in by default:

Common Web Access Log format

CUPS page_log

Syslog

Glog

VMware ESXi/vCenter Logs

dpkg.log

uwsgi

"Generic" - Any message that starts with a timestamp

Strace

sudo

GZIP'ed and BZIP2'ed files are also detected automatically and decompressed on-the-fly.

Filters

Display only lines that match or do not match a set of regular expressions. Useful for removing extraneous log lines that you are not interested in.
