批处理脚本与命令行

Question

When I run following command in cmd prompt it works: 当我在cmd提示符下运行以下命令时，它将起作用：

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

but when I run it from .bat file it does not work. 但是当我从.bat文件运行它时，它不起作用。 Saying -nln was unexpected. 说-nln是意外的。

Is there anyway I could run this from .bat file. 无论如何，我可以从.bat文件运行此文件。

Answer 1

The % character has a special meaning for command line parameters and FOR parameters. %字符对于命令行参数和FOR参数具有特殊含义。

To treat a percent as a regular character, double it: %% 要将百分比视为常规字符，请将其加倍： %%

When you execute it from a batch file, you should write it like this : 从批处理文件执行时，应这样编写：

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