Hi, is there a way to make an Entourage (on OS X) signature that would
take the text of the signature from the stdout of a shell program?
Not in 'real time', as I suspect you want.
As Bill has already replied, AppleScript can create or edit signatures,
and the shell can communicate with AppleScript and vice versa.
However, you will have to set up a repeating schedule to run the
AppleScript to update the signature at regular intervals. Schedules can
be run up to once per minute. Unfortunately, there is no way for the
signature to be updated every time a new message is created.
