Some programs require quotes on arguments. For example, httpd of Apache HTTP Server has -C and -c options that captures the white-space. Usage: ./httpd [-D name] [-d directory] [-f file] [-C "directive"] [-c "directive"] [-k start|restart|graceful|graceful-stop|stop] [-v] [-V] [-h] [-l] [-L] [-t] [-T] [-S] [-X] Options: (snip) -C "directive" : process directive before reading config files -c "directive" : process directive after reading config files (snip) https://svnweb.freebsd.org/ports/head/www/apache24/files/apache24.in?revision=362371 is using -c option. It works normally. But it doesn't work when set variable apache24_profiles and apache24_nice or apache24_user as below. apache24_enable="YES" apache24_nice="5" apache24_user="nobody" apache24_profiles="www" apache24_www_configfile="/usr/local/etc/apache24/httpd.conf"
