.TH "ROTATELOGS" 8 "2004-09-04" "Apache HTTP Server" "rotatelogs"
.SH NAME
rotatelogs \- Piped logging program to rotate Apache logs
.SH "SYNOPSIS"
.PP
\fBrotatelogs\fR [ -\fBl\fR ] \fIlogfile\fR [ \fIrotationtime\fR [ \fIoffset\fR ]] | [ \fIfilesize\fRM ]
.SH "SUMMARY"
.PP
rotatelogs is a simple program for use in conjunction with Apache's piped logfile feature\&. For example:
.nf
CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common
.fi
.PP
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\&.
.nf
CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common
.fi
.PP
This configuration will rotate the logfile whenever it reaches a size of 5 megabytes\&.
.nf
ErrorLog "|bin/rotatelogs /var/logs/errorlog\&.%Y-%m-%d-%H_%M_%S 5M"
.fi
.PP
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\&.
.SH "OPTIONS"
.TP
-l (\fI2\&.0\&.51 and later\fR)
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!
.TP
\fIlogfile\fR
The path plus basename of the logfile\&. If \fIlogfile\fR includes any '%' characters, it is treated as a format string for strftime(3)\&. Otherwise, the suffix \fI\&.nnnnnnnnnn\fR is automatically added and is the time in seconds\&. Both formats compute the start time from the beginning of the current period\&.
.TP
\fIrotationtime\fR
The time between log file rotations in seconds\&.
.TP
\fIoffset\fR
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\&.
.TP
\fIfilesize\fRM
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\&.
.SH "PORTABILITY"
.PP
The following logfile format string substitutions should be supported by all strftime(3) implementations, see the strftime(3) man page for library-specific extensions\&.
.Ip "\(bu \s-1%A\s0 \- full weekday name (localized)
.Ip "\(bu \s-1%a\s0 \- 3-character weekday name (localized)
