请教：如何使.bash_profile立即生效？[已解决]

mudeen

修改.bash_profile，建立了新的环境变量，每次都要注销--〉重新登陆之后才能使新建的环境变量生效吗？有人说直接运行./.bash_profile就行了，我试过了，还是不行。请指教。

. .bash_profile

argv

也可：
source .bash_profile

run another bash instance to replace your current running one

1. 
   
2. exec bash --login
   

复制代码

logging out and logging in again is doing the same thing as this command.
