如何格式化输出 nginx -V 的编译参数

[endoffight]

如下

---

➜ nginx nginx -V
nginx version: nginxx/x.x.x
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --prefix=/usr --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx/nginx.pid --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module --with-http_gzip_static_module --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/tmp/nginx/client --http-proxy-temp-path=/var/tmp/nginx/proxy --http-fastcgi-temp-path=/var/tmp/nginx/fcgi --with-http_stub_status_module --with-http_sub_module --with-http_spdy_module

---

现在想把configure arguments一段输出打印成：

--prefix=/usr
--sbin-path=/usr/sbin/nginx
--conf-path=/etc/nginx/nginx.conf
...
..
.

主要是为了grep起来方便，之前见过类似命令，貌似用到awk还是sed，求大神解答！

sed 's/\s+/\n/g'

忘了，+ 也要用 \
sed 's/\s\+/\n/g'
