从命令窗口，通过双击bat文件执行不同当Windows .bat文件的行为 [英] Windows .Bat file behave differently when executed from command window and by double clicking on the bat file

问题描述

从命令窗口，并通过双击bat文件执行时的Windows .bat文件的行为不同。这是我的文件：

Windows .Bat file behave differently when executed from command window and by double clicking on the bat file. This is my file:

ECHO ON
del activity_ftp.log
cd D:\My_Test
IF EXIST united_ops*.csv (
for %%i in (united_ops*.csv) do (
set size=0
set /A size=%%~zi
echo %%i,%size%,397312,624640 > D:\My_Test\activity_ftp.log
)
)

当我打开命令窗口，调用它运行它，

When I run this by opening command window and calling it,

推荐答案

有在code的一些问题。结果
CD D：\\ My_test 如果您是在只会工作，D：，你可以使用 CD / D 或 PUSHD 在这里。

There are some issues in your code.
cd d:\My_test will only work if you are on D:, you could use cd /d or pushd here.

...回声％的大小％不起作用，因为它的时候，当它执行的块不会被解析扩展。

echo ...%size% doesn't work, as it's expands when the for block is parsed not when it's executed.

的（如果存在）似乎是多余的，因为为%%我在（united_ops * .csv的）如果任何文件存在不仅扩展。

The if exist seems to be redundant, as the for %%i in ( united_ops*.csv) only expands if any file exists.

ECHO ON
setlocal EnableDelayedExpansion
del activity_ftp.log
pushd D:\My_Test
for %%i in (united_ops*.csv) do (
    set size=0
    set /A size=%%~zi         
    echo %%i,!size!,397312,624640 > D:\My_Test\activity_ftp.log
)
