查找命令行在调用可执行文件时使用的路径

问题描述

我遇到以下问题：

我想运行 ecd.exe $ b>

我已将其完整路径添加到'path'环境变量。

当从命令行调用 ecd.exe 时，得到以下输出：

 错误：ecd.exe应位于Eclipse主目录下。 
  

当我在命令行中添加完整路径时，此可执行文件正确运行。

---

我发现在其他路径文件夹中存在相同的文件。 / p>

但我在文件系统中的任何位置都找不到它。

调用此可执行文件时，命令行使用的路径？

解决方案

  @ECHO OFF 
 SETLOCAL 
 SETpathd =％cd％;％path％
 SETpathd =％pathd：）= ^）％
 FOR / f delims =%% a IN（'echo％pathd：; = ^&ECHO％'）DO IF EXIST%%〜a\j * .exeECHO %%〜a 
 
 GOTO：EOF 
  

这应该会找到 - J * .exe 路径上的文件（因为我没有 ecd.exe ） - 只需替换 ecd.exe j * .exe 。

它将当前路径追加到当前目录名， c $ c>; ，然后在结果字符串中更改每个）为 ^）

用于连接的增强型路径字符串，通过替换; 与& echo - 之前的插入符号） $ c>& 在此行中转义字符，导致 cmd 忽略特殊含义并将其视为普通字符。 / p>



每个个人 path 目录提供 %% a 反过来;查看该目录中是否存在该文件（ j * .exe ），如果找到该文件，则 echo 。

I am experiencing the following problem:

I would like to run ecd.exe from a command-line.

I have added its full path to the 'path' environment-variable.

When calling ecd.exe from command-line, I get the following output:

Error: ecd.exe should be located under the Eclipse home directory.

This executable runs correctly when I add its full path in the command-line.

---

I've figured that an identical file exists in some other path folder.

But I have not been able to find it anywhere within the file-system.

How can I find the path used by the command line when calling this executable?

解决方案

@ECHO OFF
SETLOCAL
SET "pathd=%cd%;%path%"
SET "pathd=%pathd:)=^)%"
FOR /f "delims=" %%a IN ('echo %pathd:;=^&ECHO %') DO IF EXIST "%%~a\j*.exe" ECHO %%~a

GOTO :EOF

This should find - well, J*.exe files on the path (since I don't have ecd.exe) - just substitute ecd.exe for j*.exe.

It appends the current path to the current directoryname separated by ; then changes each ) to ^) in the resulting string.

The for operates on the concatenated enhanced path-string by substituting for ; with &echo - the carets before the ) on the previous line and the & in this line "escapes" the character, cause cmd to disregard the special meaning and treat it as an ordinary character.

This provides %%a as each individual path directory in turn; see whether the file (j*.exe) exists in the directory, and echo the directoryname if the file is found.
