PATH 环境变量的定义涉及从哪些文件和步骤?

[jiyinyiyong]

同学遇到 CentOS 上 PATH 出错的问题.. 各种 "command not found"... 神奇的 cd 居然还能用...
没找到 history 里编辑过的可疑命令, 也没法排查..
我在 Arch 里有看到 /etc/profile 里声明了 PATH, 但 Ubuntu 和 CentOS 上没看到这个,,,
除了 /etc/profile 和 ~/.bashrc, ~/.bash_profile 以外, 还有哪些文件涉及到了 PATH 的定义

cd是内置命令当然能用。/etc/profile.d?
