Maybe you can use a function like this not tested one:
check_cmd() {
cmd="$1"
if type "$cmd" > /dev/null 2>&1; then
if "$cmd" -v | grep Apache > /dev/null 2>&1; then
httpd=$(echo "$cmd" | sed "s/apache2/httpd/")
fi
fi
}
One worry I have with that approach is if any and all random
implementations of "httpd" that live somewhere in path do not do any harm
when started with "-v" option. Namely, they should exit without becoming
a daemon and/or start the service.
I am not convinced that would be the case.
