  Junos tip of the day(tm): follow a log file from shell!

  1) enter the shell with ‘start shell’

  2) pick your log file in /var/log (such as /var/log/authorization)

  3) tail -f that sucker: “tail -f /var/log/authorization”

  4) watch in real time/horror as the log whizzes by!

  This is like "show log authorization | refresh" except it only updates when the log file is actually written to
