ps -ef查询进程排除grep自身影响

以查询Apache进程为例

[root@openvas ~]# ps -ef |grep httpd |sort -r -k 8 |tail -5
apache   19785  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19784  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19778  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19762  4416  0 16:28 ?        00:00:00 /usr/sbin/httpd
root     21078 11822  0 23:34 pts/0    00:00:00 grep httpd

1. 使用-v选项

$ps -ef |grep httpd |grep -v grep

[root@openvas ~]# ps -ef |grep httpd |grep -v grep |sort -r -k 8 |tail -5
apache   19787  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19785  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19784  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19778  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19762  4416  0 16:28 ?        00:00:00 /usr/sbin/httpd

2. 结合正则匹配

$ps -ef |grep [h]ttpd

[root@openvas ~]# ps -ef |grep [h]ttpd |sort -r -k 8 |tail -5
apache   19787  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19785  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19784  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19778  4416  0 16:29 ?        00:00:00 /usr/sbin/httpd
apache   19762  4416  0 16:28 ?        00:00:00 /usr/sbin/httpd
