添加/使用批量从路径删除？ [英] Add/Remove from Path using Batch?

问题描述

我想有两个批处理文件 INSTALL.BAT 和 uninstall.bat 是在同一文件夹中我的命令行程序的Program.exe 。

I want to have two batch files install.bat and uninstall.bat that are in the same folder as my command-line program program.exe.

我要的 INSTALL.BAT 到的Program.exe 的当前位置添加到系统路径环境变量。

I want the install.bat to add the current location of program.exe to the System Path environment variable.

然后我想在 uninstall.bat 来从系统中删除，以的Program.exe 的任何路径路径环境变量。

Then I want the uninstall.bat to remove any paths to program.exe from the System Path environment variable.

这是如何做到这一点任何想法？

Any ideas on how to do this?

早期解决方案会有所帮助。

一个修改过的文件，以定制适合您的情况是

A modified file to custom-fit your situation would be

@ECHO OFF
SETLOCAL
SET "batchdir=%~dp0"
SET "batchdir=%batchdir:~0,-1%"
SET "newpath="
:temploop
SET tempfile=%random%%random%%random%
IF EXIST "%temp%\%tempfile%*" GOTO temploop
SET "tempfile=%temp%\%tempfile%"
CALL :showpath >"%tempfile%"
:: This part removes the current directory from the path
FOR /f "delims=" %%p IN ('type "%tempfile%"') DO (
 CALL :addsegment "%%p"
)
DEL "%tempfile%"
IF /i "%1"=="/u" (SET "newpath=%newpath:~1%") ELSE (SET "newpath=%batchdir%%newpath%")
CALL :getresp "Apply new PATH=%newpath% [Y/N/Q]?"
IF /i "%response%"=="Y" ECHO SETX PATH "%newpath%"
GOTO :EOF

:addsegment
SET "segment=%~1"
IF /i NOT "%segment%"=="%batchdir%" SET "newpath=%newpath%;%segment%"
GOTO :eof

:getresp
SET "response="
SET /p "response=%~1 "
IF /i "%response%"=="Y" GOTO :eof
IF /i "%response%"=="Q" SET "response="&GOTO :eof
IF /i NOT "%response%"=="N" ECHO Please respond Y N or Q to quit&GOTO getresp
GOTO :eof

:showpath
ECHO(%path:;=&ECHO(%
GOTO :eof   

从本质上讲，两批都是相同的 - 唯一的区别是，对于 INSTALL 版本，该目录被添加到路径

Essentially, the two batches are the same - the only difference is that for the INSTALL version, the directory is added into the path.

由于这个原因，我只是desgned它让 thisbatch 将安装文件和 thisbatch / U 将其卸载。

For this reason, I've simply desgned it so that thisbatch would install the file, and thisbatch /u would uninstall it.

当然，程序的调用来获得最终的确定，以更改路径是可选的。

Naturally, the calling of the routine to get a final OK to change the path is optional.

我不知道你需要哪些选项的SETX，所以命令只是回显。你需要从SETX线拆下ECHO激活路径变量的设置。

I don't know which options you require for the setx, so the command is simply ECHOed. You'd need to remove the ECHO from the SETX line to activate the setting of the path variable.

还要注意SETX不设置在现有的或当前CMD实例目标变量 - 只有那些在将来创建

Note also that SETX does not set the target variable in existing or the current CMD instances - only those created in the future.

同样重要的是要记住，使用卸载在这个程序的功能将消除从路径的目录，而不考虑任何其他软件的要求。

It's also important to remember that using the uninstall feature in this routine would remove the directory from the path without regard to the requirements of any other software.
