ROTATELOGS(8)
NAME
  rotatelogs - Piped logging program to rotate Apache logs

SYNOPSIS
  rotatelogs [ -l ] logfile [ rotationtime [ offset ]] | [ filesizeM ]

SUMMARY
  rotatelogs is a simple program for use in conjunction with Apache's piped
  logfile feature. For example:

       CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common

  This creates the files /var/logs/logfile.nnnn where nnnn is the system time
  at which the log nominally starts (this time will always be a multiple of
  the rotation time, so you can synchronize cron scripts with it). At the end
  of each rotation time (here after 24 hours) a new log is started.

       CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common

  This configuration will rotate the logfile whenever it reaches a size of 5
  megabytes.

       ErrorLog "|bin/rotatelogs /var/logs/errorlog.%Y-%m-%d-%H_%M_%S 5M"

  This configuration will rotate the error logfile whenever it reaches a size
  of 5 megabytes, and the suffix to the logfile name will be created of the
  form errorlog.YYYY-mm-dd-HH_MM_SS.

OPTIONS
  -l (2.0.51 and later)
       Causes the use of local time rather than GMT as the base for the
       interval. Note that using -l in an environment which changes the GMT
       offset (such as for BST or DST) can lead to unpredictable results!

  logfile
       The path plus basename of the logfile. If logfile includes any '%'
       characters, it is treated as a format string for strftime(3).
       Otherwise, the suffix .nnnnnnnnnn is automatically added and is the
       time in seconds. Both formats compute the start time from the
       beginning of the current period.

  rotationtime
       The time between log file rotations in seconds.

  offset
       The number of minutes offset from UTC. If omitted, zero is assumed and
       UTC is used. For example, to use local time in the zone UTC -5 hours,
       specify a value of -300 for this argument.

  filesizeM
       The maximum file size in megabytes followed by the letter M to specify
       size rather than time. Use this parameter in place of both
       rotationtime and offset.

PORTABILITY
  The following logfile format string substitutions should be supported by
  all strftime(3) implementations, see the strftime(3) man page for library-
  specific extensions.

  · %A - full weekday name (localized)

  · %a - 3-character weekday name (localized)

  · %B - full month name (localized)

  · %b - 3-character month name (localized)

  · %c - date and time (localized)

  · %d - 2-digit day of month

  · %H - 2-digit hour (24 hour clock)

  · %I - 2-digit hour (12 hour clock)

  · %j - 3-digit day of year

  · %M - 2-digit minute

  · %m - 2-digit month

  · %p - am/pm of 12 hour clock (localized)

  · %S - 2-digit second

  · %U - 2-digit week of year (Sunday first day of week)

  · %W - 2-digit week of year (Monday first day of week)

  · %w - 1-digit weekday (Sunday first day of week)

  · %X - time (localized)

  · %x - date (localized)

  · %Y - 4-digit year

  · %y - 2-digit year

  · %Z - time zone name

  · %% - literal `%'
