请注意，这不是路径不完整的“命令未找到问题”。外部命令出现开始确定并 立即寻求终端输入而不是产生终端输出。
我想我已经冲洗了我的 .profile / .bashrc 文件等...但我看不到问题的原因。
我使用 mintty 2.5.1 (i686-pc-cygwin) 启动 cygwin bash 交互。运行一些脚本，然后我看到 $ 提示符。 shopt -x 已设置，因此我看到命令回显。
（MinGW 也已安装，并且位于 cygwin 之后的 DOS 路径中。）
我输入的任何外部命令都会通过从终端读取行来响应。我可以恢复 $ 提示符的唯一方法是执行一些 ctrl-c 并输入。
这是终端输出，从 cygwin 启动的脚本开始。也许前面的某个地方是我的错误。最后，我尝试运行命令“mount”和“man mount”，它们用前导“+”（来自 shopt -x）回显命令，然后读取输入。

答案1
我通过向本地卷的 FSTAB 添加条目来“破坏”我的系统，如下所示：
# /etc/fstab
#
# This file is read once by the first process in a Cygwin process tree.
# To pick up changes, restart all Cygwin processes. For a description
# see https://cygwin.com/cygwin-ug-net/using.html#mount-table
# This is default anyway:
none /cygdrive cygdrive binary,posix=0,user 0 0
c:/ /c ntfs text,posix=0 0 0
d:/ /d ntfs text,posix=0 0 0
f:/ /f ntfs text,posix=0 0 0
g:/ /g ntfs text,posix=0 0 0
我通过将 fstab 更改为“修复”它：
none /cygdrive cygdrive binary,posix=0,user 0 0
none /tmp usertemp binary,posix=0 0 0
c:/ /c ntfs binary,posix=0,cygexec 0 0
d:/ /d ntfs binary,posix=0,cygexec 0 0
f:/ /f ntfs binary,posix=0,cygexec 0 0
g:/ /g ntfs binary,posix=0,cygexec 0 0
我认为发生的情况是，通过不将 4 个驱动器（c、d、f、g）安装为“exec”，每次 cygwin 搜索外部时，它都会打开并读取大量文件来查找“magic”字节”查看该文件是否是可执行文件。
与此同时，mintty 正在缓冲我作为“提前输入”输入的内容，直到我按 ctrl-c 退出，从而终止仍在运行的对我的命令的搜索。
通过将“cygexec”添加到选项中，搜索现在仅参考目录中的可执行标志，并全速运行。
