I have built a switch box that controls the power to a device attached to my Linux Server. We have developing an application that controls the power switch by monitoring the date, time and content of a particular file looking for any change from ON to OFF or a resend of ON to cause a reset if the device has locked up.
I need to do this remotely as the switch box controls part of my VoIP service which can occasionally lock up.
My plan was to log into any one of my Windows systems and using ZtreeWIN, ECHO the file change to the monitored file on the server.
I have now realize that the "ECHO ON" and "ECHO OFF" are internal to the internal to ECHO when used in a Batch file or on the Command line so all an "ECHO ON>T:\XXX\state.txt" does is wipe out the existing state.txt file.
Is there a way around this at the command line.
Thanks
