在 Ubuntu 10.10 中永久更改环境变量
朋友们， 我想在系统范围内更改环境路径。因为我有一个名为“md5”的程序。我想从任何地方（即任何目录）执行它。
我的 md5 程序位于“/home/ahuq/MappingServer/md5_program”。所以我所做的就是在运行的SHELL中添加：“export PATH=$PATH:/home/ahuq/MappingServer/md5_program”。这只会进行临时更改，并让我可以从任何地方临时运行“md5”程序。但我想让这个改变永久化。所以我所做的就是将“PATH=$PATH:/home/ahuq/MappingServer/md5_program”行放入“/etc/environment”文件中。这把一切都搞砸了，然后有一段时间我无法从 SHELL 执行任何东西。我知道“nano”编辑器的绝对路径，并用它来将文件（即/etc/environment）修改回其原始状态。这解决了问题，现在我可以从 SHELL 运行“ls”之类的程序。
但我仍然需要一种方法将“md5”的路径永久添加到环境中。我怎样才能在 Ubuntu 10.10 中做到这一点？需要编辑哪个文件？
再见。
Friends,
I want to make change to environment PATH system wide. Because I have program called "md5". I want to execute it from anywhere (i.e any directory).
My md5 program is located at "/home/ahuq/MappingServer/md5_program". So what I did was to put: "export PATH=$PATH:/home/ahuq/MappingServer/md5_program" in the running SHELL. This only makes temporary changes and lets me run the "md5" program from anywhere temporarily. But I want to make this change permanent. So what I did was to put the "PATH=$PATH:/home/ahuq/MappingServer/md5_program" line into the "/etc/environment" file. This screwed everything up and then for a while I couldn't execute anything from SHELL. I knew the absolute path of "nano" editor and used it to modify the file (i.e. /etc/environment) back to its original condition. This fixed the problem and now I can run programs like "ls" from the SHELL.
But still I need a way to permanently add the path of "md5" to the environment. How can I do this in Ubuntu 10.10? Which file needs to edited?
Bye.

看起来您将“程序”添加到路径中，您只想将目录添加到路径中。
尝试
添加到 .profile 中定义 PATH 的位置。
我希望这有帮助。

It looks like your adding the 'program' to the path, you only want to add the directory to the path.
Try
added to where your PATH is defined in a .profile.
I hope this helps.
