errorlevel

问题 I am learning Windows batch scripting. I need to raise errors when copy, move or delete operations fail. I have made a sample script and for some reason, when the operation fails I cannot get the ERRORLEVEL to rise. I run the script and the files either do not exist or are opened in another program and stderr messages are output to console, but ERRORLEVEL never rises, why is this? Also, is there any way to pipe stderr into a variable I could check, if I cannot get ERRORLEVEL to rise? My code

问题 %errorlevel% doesn't work in WindowsXP. As I know when an error occurs %errorlevel% set 1 or above value, and if there is no error it will set 0. But, even though there is no error, %errorlevel% is 1. And I set %errorlevel% 0, even there is an error %errorlevel% is sill 0. I think OS doesn't change %errorlevel% in XP. In Win7 it work totally. @echo off setlocal enabledelayedexpansion call dir echo errorlevel=%errorlevel% REM expected errorlevel=0 but 1 call dor echo errorlevel=%errorlevel%

问题 In a DOS batch script, I'm running a single command on a remote (also windows) computer using plink. Formerly, this command was only run on the local machine, and was relying on the return code to determine success. Is there a way to easily get this information back through plink? 回答1: That's not possible with plink . The current consensus is to have the remote script echo its exit code to a log file, then use pscp to transfer the log file to the local machine. See http://fixunix.com/ssh

问题 When executing a Powershell script (in 2.0) using the -File command line switch, and explicitly defining the input parameters in Param, the exit code is always "0" (never fails) instead of properly returning the defined or expected error code. This does not occur when using the explicit parameter definitions and the -Command switch, however for extraneous purposes, I need to keep the -File switch in my scripts. Any assistance with a workaround (that doesn't involve removing the explicit

问题 I'm trying to create a batch file that performs different 'choice' command based on the version of Windows being executed on. The choice command's syntax is different between Windows 7 and Windows XP. Choice command returns a 1 for Y and 2 for N. The following command returns the correct error level: Windows 7: choice /t 5 /d Y /m "Do you want to automatically shutdown the computer afterwards " echo %errorlevel% if '%errorlevel%'=='1' set Shutdown=T if '%errorlevel%'=='2' set Shutdown=F

问题 So I know from experience that running a valid program from cmd.exe and checking the %errorlevel% will return a 0: C:\>dir logo.bmp Volume in drive C has no label. Volume Serial Number is 5283-A7A2 Directory of C:\ 05/22/2008 12:43 PM 1,440,054 logo.bmp 1 File(s) 1,440,054 bytes 0 Dir(s) 71,723,995,136 bytes free C:\>echo %errorlevel% 0 Likewise, trying to execute a command that does not exist and then checking for the %errorcode% gives me a 9009: C:\>idontexist.exe 'idontexist.exe' is not

问题 Background: I am attempting to get email notification upon failure of a scheduled task. My task can indicate failure via exit code (errorlevel) and I want to use that and follow the filter approach described in this answer to trigger an email. Problem: I am getting inconsistent behavior from Task Scheduler on different machines and versions of Windows. To test, I'm using the following very simple task. Run only when user is logged on. (where "user" is the current user) Action: Start a program

问题 I've been using batch for a while now and I just recently ran into a problem I never encountered before involving ERRORLEVELS. Here is a short program I made to show off the error. @echo off title Choices CMD /C EXIT 0 echo [1] Choice 1 echo [2] Choice 2 echo [3] Choice 3 choice /c 123 /n IF ERRORLEVEL 1 GOTO ONE IF ERRORLEVEL 2 GOTO TWO IF ERRORLEVEL 3 GOTO THREE echo Nice you broke it pause exit :ONE echo CONGRATS YOU CHOSE 1 pause exit :TWO echo NICE YOU CHOSE 2 pause exit :THREE echo OOH

问题 I've got a batch file that parses a bunch of file names out of a text file and concatenates them into a single strong - it was previously discussed here. However, I don't want the string to contain a file if the file throw an error when I run it through some command (like a VCS check, for example). Here's my attempt: set FILE_LIST= for /f %%x in (temp.txt) do ( :: perform a VCS test accurev diff -b %%x :: skip concatenation if error level is > 2 IF errorlevel 2 GOTO NEXT :: perform the
