linux "ps -ef|grep" 简写为pg

1. 执行命令创建pg文件

sudo vi /usr/local/bin/pg

    文件内容

#!/bin/bash
ps -ef|grep $1

 2. 设置权限

sudo chmod 755 /usr/local/bin/pg

完毕!

测试一下语句"pg zookeeper":

hadoop@rick-ubuntu:~$ pg zookeeper
hadoop   24231     1  0 14:08 tty2     00:00:01 /usr/lib/jvm/java-8-oracle/bin/java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /home/hadoop/work/zookeeper/bin/../build/classes:/home/hadoop/work/zookeeper/bin/../build/lib/*.jar:/home/hadoop/work/zookeeper/bin/../lib/slf4j-log4j12-1.6.1.jar:/home/hadoop/work/zookeeper/bin/../lib/slf4j-api-1.6.1.jar:/home/hadoop/work/zookeeper/bin/../lib/netty-3.7.0.Final.jar:/home/hadoop/work/zookeeper/bin/../lib/log4j-1.2.16.jar:/home/hadoop/work/zookeeper/bin/../lib/jline-0.9.94.jar:/home/hadoop/work/zookeeper/bin/../zookeeper-3.4.6.jar:/home/hadoop/work/zookeeper/bin/../src/java/lib/*.jar:/home/hadoop/work/zookeeper/bin/../conf: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /home/hadoop/work/zookeeper/bin/../conf/zoo.cfg

hadoop   27574 27572  0 14:24 pts/0    00:00:00 grep zookeeper

 同样的方法, 可以创建k9(kill -9) 和tf(tail -f)命令
