rem Poor man's logrotate for Windows command shell
|
||
|
|
|
||
|
|
rem Usage: cmd /v:on /c logrotate.cmd [-f <configfile>]
|
||
|
|
rem where <configfile> is a fully qualified name of a configuration file.
|
||
|
|
rem If <configfile> is not specified an attempt is made to locate
|
||
|
|
rem logrotatew.conf in the current directory. If it is not found the script
|
||
|
|
rem fails.
|
||
|
|
|
||
|
|
rem A configuration file specifies log file name patterns and how many
|
||
|
|
rem generations to keep. For example, a line in the configuration file:
|
||
|
|
rem "c:\temp\*.log 5" will cause rotation of every file with the extension
|
||
|
|
rem ".log" in the specified directory, keeping 5 generations of rotated files.
|
||
|
|
rem The rotated files can be optionally compressed. See comments in the sample
|
||
|
|
rem logrotatew.conf for more details.
|
||
|
|
|
||
|
|
rem The script rotates the los specified by the configuration file each time
|
||
|
|
rem it is invoked. Schedule it in Windows Scheduler as often as you need, e.g.
|
||
|
|
rem at 23:55 /every:Su cmd /v:on /c logrotatew.cmd -f c:\logrotatew.conf
|
||
|
|
|
||
|
|
rem NOTE: the script must be invoked with "cmd /v:on /c logrotate.cmd [-f <configfile>]"
|
||
|
|
rem otherwise it will not work properly!
