linux下查看进程状态

1、查看进程的启动时间和执行时间

　　使用 ps 命令 ：#ps -A -opid,stime,etime,args

$ ps -A -opid,stime,etime,args
  PID STIME     ELAPSED COMMAND
    1 May23  6-17:49:02 /sbin/init
    2 May23  6-17:49:02 [kthreadd]
    3 May23  6-17:49:02 [migration/0]
    4 May23  6-17:49:02 [ksoftirqd/0]
    5 May23  6-17:49:02 [migration/0]
    6 May23  6-17:49:02 [watchdog/0]
    7 May23  6-17:49:02 [migration/1]
    8 May23  6-17:49:02 [migration/1

2、查看线程 # ps -eLf 

# ps -eLf
UID        PID  PPID   LWP  C NLWP STIME TTY          TIME CMD
root         1     0     1  0    1 May23 ?        00:00:00 /sbin/init
root        39     2    39  0    1 May23 ?        00:00:03 [bdi-default]
root        40     2    40  0    1 May23 ?        00:00:00 [kintegrityd/0]
root        41     2    41  0    1 May23 ?        00:00:00 [kintegrityd/1]
root        42     2    42  0    1 May23 ?        00:00:00 [kintegrityd/2]
root        43     2    43  0    1 May23 ?        00:00:00 [kintegrityd/3]
root        44     2    44  0    1 May23 ?        00:00:00 [kintegrityd/4]
root        45     2    45  0    1 May23 ?        00:00:00 [kintegrityd/5]
