唤醒进程
UNIX下唤醒进程
在Solaris下面做的实验
man kill
man ps
man signal.h
方便起见，先alias一下ps，让它显示进程号，父进程号，进程状态，TTY，CPU时间，进程参数
bash-3.2$ alias ckps="ps -o pid,ppid,s,tty,time,args"
拿same-gnome做实验
bash-3.2$ same-gnome
^Z
+Stopped same-gnome
看一下当前进程状态
bash-3.2$ ckps
PID PPIDS TT TIMECOMMAND
12399 6868S pts/7 00:00 bash
12591 12399 T pts/7 00:01 same-gnome
12592 12591 T pts/7 00:00 same-gnome
12594 12399 O pts/7 00:00 ps -o pid,ppid,s,tty,time,args
ckps的结果显示，same-gnome（Pid：12591，12592）处于T(Terminated)状态。
用25号信号唤醒same-gnome （man signal.h）
bash-3.2$ kill -25 12591 12592
再ckps一下
bash-3.2$ ckps
PID PPID S TT TIME COMMAND
12399 6868 S pts/7 00:00 bash
12596 12399 O pts/7 00:00 ps -o pid,ppid,s,tty,time,args
12591 12399 S pts/7 00:01 same-gnome
12592 12591 S pts/7 00:00 same-gnome
same-gnome的状态变成S（Sleeping）了，又可以玩老。

Solaris用户进程状态
O Process is running on a processor.
S Sleeping: process is waiting for an event
to complete.
R Runnable: process is on run queue.
T Process is stopped, either by a jobcon-
trol signalorbecauseitisbeing
traced.
W Waiting: process is waiting for CPU usage
to drop to the CPU-caps enforced limits.
Z Zombiestate:processterminated and
parent not waiting.
