linux 设置path值
直接用export命令
在PATH中加入/data/test/hellow.sh脚本，使该脚本能在其他目录下执行。
[root@localhost /]# cd /data/test
[root@localhost test]# ll

[root@localhost test]# cd /
[root@localhost /]# export PATH=/data/test:$PATH????? #在$PATH中加入脚本路径
[root@localhost /]# export|grep test??????#查看$PATH

CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:CLASSPATH
PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC JAVA_HOME CLASSPATH JRE_HOME
