これはパスが不完全であり、「コマンドが見つからない問題」ではありません。外部コマンド現れる確認を開始し、 今探してください端末出力を生成する代わりに端末入力。
.profile/.bashrc ファイルなどをフラッシュしたようですが... 問題の原因を見ることができません。
私はmintty 2.5.1（i686-pc-cygwin）を使用してcygwin bashを対話的に起動します。一部のスクリプトを実行すると、$ プロンプトが表示されます。 shopt -x が設定され、コマンドがエコーされるのを見ることができます。
（MinGWもインストールされており、cygwin以降のDOSパスにあります。）
私が入力したすべての外部コマンドは、端末から行を読み取って応答します。 $プロンプトを再表示する唯一の方法は、Ctrl-Cを押してEnterを押すことです。
これは、cygwinが起動したスクリプトから始まるターミナル出力です。たぶん前のどこかに私の間違いがあるかもしれません。最後に、「mount」と「man mount」コマンドを実行してみました。このコマンドは、前に "+" (shopt -x で) が付いたコマンドをエコーし、入力を読み込みます。

答え1
次のように、ローカルボリュームのFSTABにエントリを追加してシステムを「破損」させました。
# /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
fstabを次のように変更して「固定」しました。
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
私が考えるために4つのドライブ（c、d、f、g）を「exec」としてマウントしないと、cygwinが外部から検索するたびに「魔法の」バイトを見つけるために複数のファイルを開いて読み取ることができます。ファイルが実行可能な場合。
一方、minttyは私がctrl-cを押して終了するまで、私の入力をTypeAheadにバッファリングして、私のコマンドに対して実行中の検索を終了します。
オプションに "cygexec"を追加すると、検索はディレクトリの実行可能フラグのみを参照し、最大速度で実行されます。
