NAME

       lnav - ncurses-based log file viewer

SYNOPSIS

       lnav [-hVsar] [logfile1 logfile2 ...]

DESCRIPTION

       The  log  file navigator, lnav, is an enhanced log file viewer that takes advantage of any
       semantic information that can be gleaned from the files being viewed, such  as  timestamps
       and  log  levels.   Using  this  extra  semantic  information,  lnav  can  do  things like
       interleaving messages from different files, generate histograms of messages over time, and
       providing  hotkeys  for navigating through the file.  It is hoped that these features will
       allow the user to quickly and efficiently zero in on problems.
