具有相对路径和关闭命令提示符的批处理文件 [英] batch file with relative path and close command prompt

问题描述

我尝试以下代码:

start /d "D:\test\CONTOH\DATA\QGIS2\bin\" qgis.bat

基于:在命令提示符下运行.exe的蝙蝠文件

但是，我想成为相对路径，像这样:

But, I want to be relative path, something like this :

start /d %~dp0\DATA\QGIS2\bin\qgis.bat

基于: BAT脚本中的相对路径

但是什么也没发生.那么，有人可以给我信息，怎么了?

but, nothing happen. So, can someone give me information, what is wrong?

推荐答案

打开命令提示符窗口，然后运行 start/?.这将输出命令 START 的帮助，使用该命令时应阅读该帮助以了解有关其选项的信息.

Open a command prompt window and run start /?. This outputs the help for the command START which should be read on using this command to get knowledge about its options.

在命令提示符窗口中运行 call/?并阅读输出帮助页面以了解％〜dp0 .批处理文件的驱动器和路径(参数0)始终以反斜杠结尾.因此，不要在将其与另一个字符串连接时添加额外的反斜杠.

Run in command prompt window call /? and read the output help pages to understand %~dp0. The drive and path of the batch file (argument 0) always ends with a backslash. Therefore don't add an extra backslash on concatenating it with another string.

第一个双引号字符串由 START 解释为在新窗口的标题栏中显示的新控制台窗口的标题.因此，最好在启动GUI应用程序时根本没有打开任何控制台窗口的情况下，始终指定标题字符串，也可以是空字符串，例如" .

And the first double quoted string is interpreted by START as title for the new console window displayed in title bar of the new window. Therefore better specify always a title string which can be also an empty string like "" in case of starting a GUI application on which no console window is opened at all.

start "Running QGIS2" /D "%~dp0DATA\QGIS2\bin" qgis.bat

也可以在批处理文件中使用此命令行:

Also possible is using this command line in batch file:

start "Running QGIS2" /D"%~dp0DATA\QGIS2\bin" qgis.bat

根据/D％〜dp0DATA \ QGIS2 \ bin" 的定义，此处从目录开始根据命令 START 作为一个参数字符串.

Here start in directory as defined with /D"%~dp0DATA\QGIS2\bin" is 100% correct specified according to help of command START as one parameter string.

但是Windows命令解释器也接受带有选项/D 的第一个变体，但不带任何文件夹路径，而在下一个参数字符串％〜dp0DATA \ QGIS2 \ bin" 分隔空间是从目录开始的文件夹路径.

But Windows command interpreter accepts also the first variant with just option /D without any folder path and next parameter string "%~dp0DATA\QGIS2\bin" after a separating space is the folder path for start in directory.

与/D 作为一个参数字符串和％〜dp0DATA \ QGIS2 \ bin" 作为一个参数字符串的第一个变量相比，它更易于阅读第二个变体，其中/D％〜dp0DATA \ QGIS2 \ bin" 仅是一个参数字符串.

The first variant with just /D as one parameter string and "%~dp0DATA\QGIS2\bin" as one more parameter string is easier to read in comparison to second variant with /D"%~dp0DATA\QGIS2\bin" being just one parameter string.
