我使用过的Linux命令之ps - 显示当前正在运行的进程列表
我使用过的Linux命令之ps - 显示当前正在运行的进程列表
本文链接：http://codingstandards.iteye.com/blog/841996 ? （转载请注明出处）
用途说明ps命令是Process Status的缩写（ps is the shortage for Process Status.）。ps命令用来列出系统中当前运行的那些进程（The command should be used to display thecurrently running processes on Unix/Linux systems.）。ps命令列出的是当前那些进程的快照（report a snapshot of the current processes），就是执行ps命令的那个时刻的那些进程，如果想要动态的显示进程信息，就可以使用top命令（ps displays information about a selection of the active processes. If you want a repetitive update of the selection and the displayed information, use top(1) instead.）。
?
常用参数ps命令参数可以支持不同的风格，而且又多，实在很难一一列出，下面只列出常用的方式。列位看官也可以补充一下您的常用方式。
?
格式：ps
只列出当前终端有关的进程。
?
格式：ps -ef
格式：ps aux???? <== BSD syntax
显示所有的进程（To see every process on the system using standard syntax）。通常和grep/egrep等命令配合使用来查找相关的进程。
格式：COLUMNS=1024 ps h -C java -f
显示java进程的完整信息。（h表明不显示头部信息，-C指定命令名称，-f列出全部信息）
?
使用示例示例一 查看当前shell中的进程[root@web ~]# ps
? PID TTY????????? TIME CMD
?5488 pts/12?? 00:00:00 bash
29720 pts/12?? 00:00:00 ps
[root@web ~]# ps -l
F S?? UID?? PID? PPID? C PRI? NI ADDR SZ WCHAN? TTY????????? TIME CMD
4 S???? 0? 5488 26086? 0? 75?? 0 -? 1753 wait?? pts/12?? 00:00:00 bash
4 R???? 0 29727? 5488? 0? 76?? 0 -? 1320 -????? pts/12?? 00:00:00 ps
[root@web ~]#
?
示例二 ps与grep配合查找进程通常查找进程的目的是确认程序是否正在运行、或者准备把它kill掉。
[root@web imx_server]# ps -ef|grep update.sh??
root???? 10683 17963? 0 13:52 pts/7??? 00:00:00 /bin/sh ./update.sh
root???? 26342? 5488? 0 16:25 pts/12?? 00:00:00 grep update.sh
[root@web imx_server]# ps -ef|grep update.sh|grep -v grep
root???? 10683 17963? 0 13:52 pts/7??? 00:00:00 /bin/sh ./update.sh
[root@web imx_server]# kill 10683
[root@web imx_server]#
?
示例三 查看java进程的完整信息使用ant启动的java进程命令行都相当的长。

示例四 一个显示java进程的脚本脚本sj.sh。使用方式：不跟参数显示所有java进程，跟上特征参数则显示包含此特征的java进程，特征参数可以是类名、目录名等。
