  CORRECT about UNIX files, INCORRECT about "logger rotate" command.

  CORRECTION:

  "logger rotate" does:

  1. Closes the files
  2. Renames them (actually rotating them)
  3. Reopnes the canonical named files

  "logger reload" does effectively work as you described:

  1. Closes files
  2. Reopens canonical named files

  This is the command that should be used with logrotate, for
  example.


  EXAMPLE: (consider asterisk running and writing to messages file)

  # cd /var/log/asterisk
  # mv messages messages.old

  (asterisk still running and now writing to messages.old)
  (there is no file named messages)

  # /usr/sbin/asterisk -rx "logger reload"

  (asterisk closed messages.old and created a new messages file)


  Hope this is clear enough as its really late now...
  Please correct me if I'm wrong

  Cheers
