arguments = "-e"
outputFile = "C:\Temp\output.txt"

</cfexecute>
outputFile Optional File to which to direct program output. If no
outputfile or
variable attribute is specified, output is displayed on the page
from which it was called.
If not an absolute path (starting a with a drive letter and a colon,
or a forward or backward slash), it is relative to the ColdFusion
temporary directory, which is returned by the
GetTempDirectory
function.

outputfile or
variable attribute is specified, output is displayed on page
from which it was called.
timeout Optional 0 Length of time, in seconds, that ColdFusion waits for output
from the spawned program.
• 0: equivalent to nonblocking mode.

If the value is 0:
• ColdFusion starts a process and returns immediately.

displays, set the value to 2 or higher.
