命令ERRORLEVEL由一批循环执行 [英] Errorlevel of command executed by batch for loop

问题描述

以下code总是显示为0的错误级别，但是当copy命令外面做了循环命令返回一个非零错误级别。

The following code always displays 0 as the errorlevel, but when the copy command is done outside of the for loop command it returns a non zero errorlevel.

for /f "usebackq delims=" %%x in (`copy x y`) do (
    set VAR=%%x
)
ECHO Errorlevel = %ERRORLEVEL%
ECHO VAR = %VAR%

时有可能获得由循环执行的复制命令的ERRORLEVEL？

Is is possible to get the errorlevel of the copy command executed by the for loop?

推荐答案

我的作品！你只需把错误的DO括号内检查
用含有复制命令（7200行的文本文件;例如：
副本2_97691_Scan.pdf○：\\ DATA \\开发\\敏思\\ PDFScan2 \\ 2011 \\ 4 \\ 2_97691_Scan.pdf）
我可以运行以下批处理文件

it works for me ! You only need to put the error checking within the DO parentheses with a text file containing the copy commands (7200 lines; for example: copy 2_97691_Scan.pdf O:\Data\Dev\Mins\PDFScan2\2011\4\2_97691_Scan.pdf), I can run the following batch file

@echo off

setlocal EnableDelayedExpansion

for /F "delims=" %%I in (CopyCurrentPDFs.txt) do (
%%I
if !errorlevel! NEQ 0 echo %%I>>errorcopy.txt
)
