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
     May23  -:: /sbin/init
     May23  -:: [kthreadd]
     May23  -:: [migration/]
     May23  -:: [ksoftirqd/]
     May23  -:: [migration/]
     May23  -:: [watchdog/]
     May23  -:: [migration/]
     May23  -:: [migration/

2、查看线程 # ps -eLf

# ps -eLf
UID        PID  PPID   LWP  C NLWP STIME TTY          TIME CMD
root                          May23 ?        :: /sbin/init
root                        May23 ?        :: [bdi-default]
root                        May23 ?        :: [kintegrityd/]
root                        May23 ?        :: [kintegrityd/]
root                        May23 ?        :: [kintegrityd/]
root                        May23 ?        :: [kintegrityd/]
root                        May23 ?        :: [kintegrityd/]
root                        May23 ?        :: [kintegrityd/]
