Blocknotify and Walletnotify

Question

Can someone please give an example of using blocknotify and walletnotify? These are what i tried for:

multichaind mychain -daemon blocknotify myecho      # myecho is a working script to echo hello world

multichaind surveychain -daemon blocknotify echo "hello world"

Thanks.

Answer 1

These work as regular runtime parameters, and you're probably better off putting them in the multichain.conf file so you don't have to set them each time. Inside that file you would use the following form:

blocknotify=/path/to/script %s

walletnofify=/path/to/script %s

If you want to use them on the command line, use the form -blocknotify=/path/to/script

Please note you cannot put the shell command directly in the parameter value - it needs to be a path to a file that can be executed.
