批处理脚本与命令行 [英] Batch script vs command line

问题描述

当我在cmd中运行以下命令时，它会起作用:

When I run following command in cmd prompt it works:

for /R %f in (*.shp) do ogr2ogr -nln merge -update -append merge.shp %f 

但是当我从.bat文件运行它时，它不起作用.说-nln是意外的.

but when I run it from .bat file it does not work. Saying -nln was unexpected.

无论如何，我可以从.bat文件中运行它.

Is there anyway I could run this from .bat file.

推荐答案

%字符对于命令行参数和FOR参数具有特殊含义.

The % character has a special meaning for command line parameters and FOR parameters.

要将百分比视为常规字符，请将其加倍:%%

To treat a percent as a regular character, double it: %%

从批处理文件执行时，应这样写:

When you execute it from a batch file, you should write it like this :

@echo on
for /R %%f in (*.shp) do ogr2ogr -nln merge -update -append merge.shp %%f 
pause
