how to make changes in .bashrc effective in current terminal
提问by damon
I have an open terminal in ubuntu lucid in which I need a new env variable set.So,I open the .bashrc file and edit it ,to add the new env variable( say PYTHONPATH)
我在 ubuntu lucid 中有一个开放终端，我需要一个新的 env 变量集。所以，我打开 .bashrc 文件并编辑它，以添加新的 env 变量（比如 PYTHONPATH）
.bashrc
.bashrc
PYTHONPATH=/some/path
export PYTHONPATH
But,in order to get this effective ,I need to close my terminal and open it again.Is there some command with which I can get this effect,without close/open the terminal again.
但是，为了使其有效，我需要关闭我的终端并再次打开它。是否有一些命令可以使我获得这种效果，而无需再次关闭/打开终端。

Take a look at the sourcecommand: man source
看一下source命令：man source
source ~/.bashrc
Apart from that: why don't you simply use the environment commands directly in your shell to set an additional environment variable?
除此之外：为什么不直接在 shell 中使用环境命令来设置额外的环境变量？
export PYTHONPATH="/some/path"
That way the created variable is effective right away.
这样创建的变量立即生效。
