First, demand:

Second, the settlement:

#!/Bin/sh# (Sh pid_monitor.sh)&#被监控的进程放在后台运行 whiletrue #死循环不断监控后台运行的进程do pid_num=' PS-Ef|Grep-V grep|grep root_sub_i2_data|Awk'{print $}'|Wc-l ' #取后台运行程序的进程号数量if [$pid _num-gt 1]; #判断被监控的进程数是否大于1, note the semicolon, the shell and Python are different ThenEcho'to monitor multiple exception processes:' >>Pid_monitor.LogPS-Ef|Grep-V grep|grep root_sub_i2_data|Awk'{print $2,$5}' >>Pid_monitor.Log#打印进程号和启动时间Elseecho ' Date ''only monitor the number of 1 processes, normal ...' >>Pid_monitor.LogSleep -#休息30秒 Fidone
