Command Failed With Error Code 1
from a Windows command line? up vote 465 down vote favorite 95 I am running a program and want to see what its return code is (since it returns different codes based on different errors). I know in Bash I can do this by running echo $? What do I do when using cmd.exe on Windows? windows command-line process cmd exit-code share|improve this question asked Dec 2 bash error code of last command '08 at 18:04 Skrud 3,56331622 5 Also asked on SuperUser: How to check the exit code of the last command in batch file? –Deanna Jun 24 '13 at 11:42 add a comment| 6 Answers 6 active oldest votes up vote 572 down vote accepted A pseudo environment variable named errorlevel stores the exit code: echo Exit Code is %errorlevel% Also, the if command has a special syntax: if errorlevel See if /? for details. Example @echo off my_nify_exe.exe if errorlevel 1 ( echo Failure Reason Given is %errorlevel% exit /b %errorlevel% ) Warning: If you set an environment variable name errorlevel, %errorlevel% will return that value and not the exit code. Use (set errorlevel=) to clear the environment variable, allowing access to the true value of errorlevel via the %errorlevel% environment variable. share|improve this answer edited Aug 9 at 16:11 Dave Jarvis 16.4k24105204 answered Dec 2 '08 at 18:07 Samuel Renkert 6,80821626 17 If you're running directly from a Windows command line and always seeing 0 returned, see Gary's answer: stackoverflow.com/a/11476681/31629 –Ken Aug 30 '12 at 13:51 1 Also if you're in powershell you can use echo Exit Code is $LastExitCode –Brandon Pugh Jan 16 '14

A successful command returns a 0 while an unsuccessful one returns a non-zero value that usually can be interpreted as an Error Code. The last command executed in the function or the script determines the exit status. This document provides steps on how to https://www.manageengine.com/products/desktop-central/returning-error-code-on-scripts-how-to.html return the error codes on .vb scripts, Powershell scripts and batch files. Steps Exit codes for batch files Use the command EXIT /B %ERRORLEVEL% at the end of the batch file to return the error codes from the batch file EXIT /B at the end of the batch file will stop execution of a batch file. use EXIT /B < exitcodes > at the end of the batch file to return custom return codes. Environment variable %ERRORLEVEL% contains the latest errorlevel in the batch file,which is the latest error codes from the last command executed. To know about Environment variable see the below note. Note: Environment variables are a set of dynamic named values that can affect the way, running processes will behave on a computer. For example, an environment variable with a standard name can store the location that a particular computer system uses to store user profile this may vary from one computer system to another. In the batch file , it is always a good practice to use environment variables instead of constant values. Since the same variable get expanded to different values on different computers.

and Signals and Traps (Oh My!) - Part 1 by William Shotts, Jr. In this lesson, we're going to look at handling errors during the execution of your scripts. The difference between a good program and a poor one is often measured in terms of the program's robustness. That is, the program's ability to handle situations in which something goes wrong. Exit status As you recall from previous lessons, every well-written program returns an exit status when it finishes. If a program finishes successfully, the exit status will be zero. If the exit status is anything other than zero, then the program failed in some way. It is very important to check the exit status of programs you call in your scripts. It is also important that your scripts return a meaningful exit status when they finish. I once had a Unix system administrator who wrote a script for a production system containing the following 2 lines of code: # Example of a really bad idea cd $some_directory rm * Why is this such a bad way of doing it? It's not, if nothing goes wrong. The two lines change the working directory to the name contained in $some_directory and delete the files in that directory. That's the intended behavior. But what happens if the directory named in $some_directory doesn't exist? In that case, the cd command will fail and the script executes the rm command on the current working directory. Not the intended behavior! By the way, my hapless system administrator's script suffered this very failure and it destroyed a large portion of an important production system. Don't let this happen to you! The problem with the script was that it did not check the exit status of the cd command before proceeding with the rm command. Checking the exit status There are several ways you can get and respond to the exit status of a program. First, you can examine the contents of the $? environment variable. $? will contain the exit status of the last command executed. You can see this work with the following: [me] $ true; echo $? 0 [me] $ false; echo $? 1 The true and false commands are programs that do nothing except return an exit status of zero and one, respectively. Using them, we can see how the $? environment variable contains the exit status of the previous program. So to check the exit status, we could write the script this way: # Check the exit status cd $some_directory if [ "$?" = "0" ]; then rm * else echo "Cannot change directory!" 1>&2 exit 1 fi In this version, we examine the exit status of the cd command and if it's not zero, we print an error message on standard error and terminate the script with an exit status of 1. While th
