I get ugly output in buffer "*Async Shell Command*". and an error message: exited abnormally with code 1. Perhaps some shell color codes are, well, "async"! (So yes, in principle it should work.) Anyway without digging into that, I have another function that will do the job if an ampersand (&) is appended the command. Here it is: (defun shell-command-silent (command) "Execute a shell COMMAND. Use & after the command to execute it in the background, without output to the echo area."
