shell脚本，怎么实现每次新开一个shell都输出一个提示语？

[root@localhost wyb]# cat test.sh 
echo -e "\033[32mhello,This is wangyuebo‘s shell\033[0m"
echo -e "\033[32m`date`\033[0m"
LANG=en
echo -e "\033[32m`date` login at `hostname` `w`\033[0m" >>/etc/wangyuebo.log
[root@localhost wyb]# 

当写好了提示语在test.sh脚本里面，这时把脚本放到~/.bashrc文件里面就可以了 bash /root/wyb/test.sh

[root@localhost wyb]# cat ~/.bashrc
# .bashrc

# User specific aliases and functions

alias rm=‘rm -i‘
alias cp=‘cp -i‘
alias mv=‘mv -i‘

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi
bash /root/wyb/test.sh
[root@localhost wyb]# 

然后在重新打开一个shell,就可以看到在test.sh设置的提示语了
