清理在bash $ PATH [英] cleaning up $PATH in bash

问题描述

我的道路有很多添加不久前脚本条目。他们是不是在我的.bashrc，.bash_profile中，或.bash_login文件。

My path has a lot of entries that were added long ago by scripts. They are not in my .bashrc, .bash_profile, or .bash_login.

我担心，在.bashrc中重置我的道路将有不良的长期结果。有没有办法寻找到的东西已经被添加到我的道路，并手动删除它们？事情总是由文件添加或路径缓存的地方？如果是后者，是很容易清理一下？

I'm worried that resetting my path in .bashrc will have undesirable long-term results. Is there a way to find where things have been added to my path and remove them manually? Are things always added by file or is path cached somewhere? If the latter, is it easy to clean that up?

推荐答案

最简单的方式找到的谁修改您的 PATH 是运行：

The easiest way to find who modified your PATH is to run:

  $ bash --login -i -xv 2>&1 | grep ' \. '

例如我有：

+ . /etc/profile.d/bash_completion.sh
        . /etc/bash_completion
++ . /etc/bash_completion
+++ . /etc/bash_completion.d/abook
+++ . /etc/bash_completion.d/ant
+ . /etc/profile.d/lapack0.sh
+ . /etc/profile.d/openssl.sh
+ . /etc/profile.d/qt3-devel.sh
+ . /etc/profile.d/tetex-profile.sh
+ . /etc/profile.d/xinit.sh
+ . /etc/bash.bashrc
