Usage\r
-----\r
running the service.\r
\r
\r
+File rotation\r
+-------------\r
+When using I/O redirection, NSSM can rotate existing output files prior to\r
+opening stdout and/or stderr. An existing file will be renamed with a\r
+suffix based on the file's last write time, to millisecond precision. For\r
+example, the file nssm.log might be rotated to nssm-20131221T113939.457.log.\r
+\r
+NSSM will look in the registry under\r
+HKLM\SYSTEM\CurrentControlSet\Services\<service>\Parameters for REG_DWORD\r
+entries which control how rotation happens.\r
+\r
+If AppRotateFiles is missing or set to 0, rotation is disabled. Any non-zero\r
+value enables rotation.\r
+\r
+If AppRotateSeconds is non-zero, a file will not be rotated if its last write\r
+time is less than the given number of seconds in the past.\r
+\r
+If AppRotateBytes is non-zero, a file will not be rotated if it is smaller\r
+than the given number of bytes. 64-bit file sizes can be handled by setting\r
+a non-zero value of AppRotateBytesHigh.\r
+\r
+Rotation is independent of the CreateFile() parameters used to open the files.\r
+They will be rotated regardless of whether NSSM would otherwise have appended\r
+or replaced them.\r
+\r
+\r
Environment variables\r
---------------------\r
NSSM can replace or append to the managed application's environment. Two\r
srvany only supports AppEnvironment.\r
\r
\r
+Managing services using the GUI\r
+-------------------------------\r
+NSSM can edit the settings of existing services with the same GUI that is\r
+used to install them. Run\r
+\r
+ nssm edit <servicename>\r
+\r
+to bring up the GUI.\r
+\r
+NSSM offers limited editing capabilities for services other than those which\r
+run NSSM itself. When NSSM is asked to edit a service which does not have\r
+the App* registry settings described above, the GUI will allow editing only\r
+system settings such as the service display name and description.\r
+\r
+\r
Removing services using the GUI\r
-------------------------------\r
NSSM can also remove services. Run\r
