To use `shell-command' like that means
everything halts until the command has been
executed, which we can't have, but simply
putting an "&" after - to make it
"asynchronous" which is a nice way of saying
the command will be executed in yet another
shell, a subshell - that won't work. 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."
(process-file shell-file-name
nil ; INFILE
nil ; BUFFER
nil ; DISPLAY
shell-command-switch command) )
