Question

在msysGit中，当我运行type -a tee(.exe)时，它会显示3行同一个文件：

$ 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

然而，当我在同一台机器上运行的Fedora 20 VM中输入相同的行时，情况并非如此：

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

为什么会这样？

我发现我的PATH有几次重复的文件夹。感谢@rojomoke指出了可能性。

我的msysGit路径

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`

正在试验。这一行调用Git Bash启动时调用的所有脚本，但是，正如您可能想象的那样，它在已调用的脚本上调用它们，因此任何文件都添加到PATH再次添加。

type命令显示3个相同的文件位置
