linux - type 命令显示 3 个相同的文件位置

Question

在 msysGit 中，当我运行type -a tee(.exe)时，它显示了同一文件的 3 行:

$ type -a tee.exe
tee.exe is /bin/tee.exe
tee.exe is /bin/tee.exe
tee.exe is /bin/tee.exe
tee.exe is /c/Program Files (x86)/Git/bin/tee.exe
tee.exe is /c/Program Files (x86)/Drush/GnuWin32/bin/tee.exe

但是，当我在同一台计算机上运行的 Fedora 20 VM 中输入同一行时，情况并非如此:

[sean@localhost ~]$ type -a tee
tee is /bin/tee
tee is /usr/bin/tee

为什么会发生这种情况？

我发现我的路径中有一些文件夹重复了好几次。感谢@rojomoke 指出了这种可能性。

我的 msysGit 路径是

$ echo $PATH

这是因为我正在尝试登录 Git Bash。我找到了调用 Git Bash 的快捷方式:

`/bin/sh --login -i`

并且正在尝试。此行调用 Git Bash 启动时调用的所有脚本，但正如您可能想象的那样，它在已调用的脚本之上调用它们，因此添加到 PATH 的任何文件都会再次添加。
