终端调用函数

在HOME目录下的profile文件中定义函数，可以直接调用

[root@localhost ~]# vim $HOME/.profile
#!/bin/bash
function tomcat(){
   param=$1
   case $param in
       "start")
       /usr/local/tomcat8.0.39/bin/startup.sh
       ;;
       "stop")
       /usr/local/tomcat8.0.39/bin/shutdown.sh
       ;;
       "restart")
       /usr/local/tomcat8.0.39/bin/shutdown.sh
       /usr/local/tomcat8.0.39/bin/startup.sh
       ;;
       *) echo "please exec right command"
       ;;
   esac
}

[root@localhost ~]# source $HOME/.profile #使文件立即生效
[root@localhost tomcat8.0.39]# tomcat start(参数)
