linux下设置部分目录和应用的快捷方式

用户根目录.profile文件里面设的：
alias bin="cd /home/portalone0125/tomcat/bin"
alias log="cd /home/portalone0125/tomcat/logs;tail -f catalina.out"
alias stt="cd /home/portalone0125/tomcat/bin;/home/portalone0125/tomcat/bin/startup.sh;touch /home/portalo
ne0125/tomcat/logs/catalina.out;tail -f /home/portalone0125/tomcat/logs/catalina.out"
alias conf="cd /home/portalone0125/tomcat/conf"
alias app="cd /home/portalone0125/tomcat/webapps"
alias p="ps -ef |grep portalone0125"
alias stp="cd /home/portalone0125/tomcat/bin;/home/portalone0125/tomcat/bin/stop.sh"
alias rst="stp;stt"
alias pt="cd /home/portalone0125/tomcat/server/webapps/portal"

另外tomcat/bin下面加了一个我写的stop.sh脚本文件用来停止tomcat进程：
#!/bin/sh
cur_path=`pwd`
ps_no=`ps -ef |grep $cur_path |awk '{print $2}'`
kill -9 $ps_no
