NAME

qsrotate - a log rotation tool (similar to Apache's rotatelogs).

qsrotate -o <file> [-s <sec> [-t <hours>]] [-b <bytes>] [-f] [-z] [-g <num>] [-u <name>] [-m <mask>] [-p] [-d]

qsrotate reads from stdin (piped log) and writes the data to the provided file rotating the file after the specified time.

-o <file>: Output log file to write the data to (use an absolute path).
-s <sec>: Rotation interval in seconds, default are 86400 seconds.
-t <hours>: Offset to UTC (enables also DST support), default is 0.
-b <bytes>: File size limitation (default/max. are 2147352576 bytes, min. are 1048576 bytes).
-f: Forced log rotation at the specified interval even no data is written.
-z: Compress (gzip) the rotated file.
-g <num>: Generations (number of files to keep).
-u <name>: Become another user, e.g. www-data. -m <mask> File permission which is either 600, 640, 660 (default) or 664.
-p: Writes data also to stdout (for piped logging). -d Line-by-line data reading prefixing every line with a timestamp.

TransferLog "|/usr/bin/qsrotate -f -z -g 3 -o /var/log/apache/access.log -s 86400"

The name of the rotated file will be /dest/filee.YYYYmmddHHMMSS where YYYYmmddHHMMSS is the system time at which the data has been rotated.

- Each qsrotate instance must use an individual file.
- You may trigger a file rotation manually by sending the signal USR1 to the process.
