终于找到一个方法了, 先找到 pid, 然后 cat /proc/<pid>/cmdline
root@SmallWit:~# ps -Af |grep wpa
root 275 1 0 08:00 ? 00:00:00 /sbin/wpa_supplicant -u -s -O /run/wpa_supplicant
root 406 352 0 08:24 ttyS0 00:00:00 grep wpa
root@SmallWit:~# cat /proc/275/cmdline
/sbin/wpa_supplicant-u-s-O/run/wpa_supplicant
root@SmallWit:~#
root@SmallWit:~#离线
奇怪了, 上面的命令行参数居然没有空格.

还是前面那个参考链接:
You can simply use:
ps -o args= -f -p ProcessPid
然后我再试了一下, 这次正常了.
root@SmallWit:~# ps -o args= -f -p 275
/sbin/wpa_supplicant -u -s -O /run/wpa_supplicant离线
ps显示不全，2楼方法正解。
