I suggested a solution for this a while ago:
((echo hello world; false; echo $? >&3) | logger) 3>&1
You then get the exit status on stdout. Generalizing a bit:
to_syslog () {
return "$((("$@"; echo $? >&3) | logger) 3>&1)"
}
This works for me in my tests using bash, anyway. Somebody might want to
check that the "$(..."..."...)" construction works in dash.
