:: Nohup-like utility for windows written with zero dependencies on non-standard code.
|
||||
::
|
||||
:: Usage forget process_name fullpath arguments
|
||||
::
|
||||
:: Ex. forget tomcat c:\apps\tomcat start
|
||||
::
|
||||
:: Uses the schtasks command to launch whatever the command is in the next minute.
|
||||
:: If the process is already running, it is shutdown first.
