change PATH permanently on Ubuntu
提问by socksocket
I'd like to add to PATH the value ":/home/me/play/"
for the installation of Play! framework.
so I ran this command:
我想为 PATH 添加值 ":/home/me/play/"
以安装 Play！框架。
所以我运行了这个命令：
PATH=$PATH:/home/me/play
it worked. but in the next time I checked, the value changed back to the old one.
有效。但是在我下次检查时，该值又变回了旧值。
so I guess I didn't "saved" the new value, right?
所以我想我没有“保存”新值，对吧？
how do you do that?

in order to immediately reflect changes to your current terminal instance.

Assuming you want to add this path for all users on the system, add the following line to your /etc/profile.d/play.sh(and possibly play.csh, etc):
假设您要为系统上的所有用户添加此路径，请将以下行添加到您的/etc/profile.d/play.sh（可能play.csh，等等）：
PATH=$PATH:/home/me/play
export PATH
