profile from the command line?
How can I reload .bash_profile from the command line? I can get the shell to recognize changes to .bash_profile by exiting and logging back in but I would like to be able to do it on demand.
Simply type source ~/.bash_profile
Alternatively, if you like saving keystrokes you can type . ~/.bash_profile . ~/.bash_profile
. ~/.bash_profile
只要确保你没有任何对当前状态的依赖。
Simply type:
. ~/.bash_profile
However, if you want to source it to run automatically when terminal starts instead of running it every time you open terminal, you might add . ~/.bash_profile . ~/.bash_profile to ~/.bashrc file.
Note:
When you open a terminal, the terminal starts bash in (non-login) interactive mode, which means it will source ~/.bashrc .
~/.bash_profile is only sourced by bash when started in interactive login mode . That is typically only when you login at the console (Ctrl+Alt+F1..F6), or connecting via ssh .
