Sorry I over-looking this. I just tested with this new fix. IT WORKS.

That's not matching to my environment. My script is calling execute
within a if block but not as a test but it IS providing input (but not get
any output if that matters)

if ...
{
   execute :input "test input" "test";
}

Only thing still unsolved is my other thread don't know why the exectued
script has no filesystem access? (like "touch /tmp/test" ignored no error)

Also is the only different between direct and socket execute that with
socket I can run the script with more restricted owner and permissions?
Are there other differences?
