Chen - MSFTSeptember 26, 200815 0 0 0 The command interpreter cmd.exe has a concept known as the error level, which is the exit code of the program most recently run. You can test the error level dos error code 1 with the IF ERRORLEVEL command: IF ERRORLEVEL 1 ECHO error level is dos error 53 1 or more
Dos Error Handling
This was presumably because there were programs that expressed different degrees of failure with higher and higher exit codes. For example, the diff program has three exit codes: 0 means http://stanislavs.org/helppc/dos_error_codes.html the files are the same; 1 means the files are different; 2 means that something terrible happened. There are also programs that use an exit code of zero to mean success and anything else to mean failure. In addition to this internal state, you can, if you wish, create an environment variable with the name ERRORLEVEL, in the same way https://blogs.msdn.microsoft.com/oldnewthing/20080926-00/?p=20743 that you can create an environment variable called FRED. But, as with FRED, that variable won't have any effect on the error level. rem this next command sets the error level to zero CMD /C EXIT 0 set ERRORLEVEL=1 if ERRORLEVEL 1 echo Does this print? The message is not printed because the ERRORLEVEL environment variable has no effect on the error level. It's just a variable whose name happens to coincide with a command processor concept. set BANKBALANCE=$1,000,000.00 "Hey, when I tried to withdraw the money, I got an insufficient funds error. What am I doing wrong?" Now, it does happen to be the case that if command extensions are enabled and you say %ERRORLEVEL%, then the command processor first looks for an environment variable called ERRORLEVEL, and if it can't find one, then it replaces %ERRORLEVEL% with the current value of the internal error level value. It's a fallback step, in the same way that your neighbor is a fallback delivery location if you aren't home. If you file a change-of-address form for yourself, that doesn't affect packages se
task. Batch file decisions may be made based on what code was generated. This webpage gives a short discussion of these codes and ways in which they might be used. Deep detail will not be http://www.chebucto.ns.ca/~ak621/DOS/ExitCode.html gone into. If you want to know more, see your DOS manual and/or the On-Screen Help. Be aware that not everything presented here may work as shown for the commands included with the version or manufacturer of DOS you have. INFORMATION BELOW MAY NOT BE REPRODUCED WITHOUT PERMISSION FROM THE AUTHOR © What are Exit Codes? When DOS or its software finishes a command operation, it usually generates a code upon exiting. When it gives that exit code, dos error it is essentially saying: Here are the results of my work. Since these are generated after a command has finished and exited, they are known as "Exit Codes". These codes are hidden from the user but may be tested for via various methods. The codes give the computer system an idea of what happened during an operation or after it has completed. One code might signal that the task ended with no errors, or that it ended with no dos error 5 errors but that the operation was not successful. If an error did occur, a code might be generated depending on what the error was. Why Might I Want to Use Exit Codes? Since these codes can indicate what happened during a computer operation, they can be used in a batch file to tailor the direction of further procedures. So as an example, if one used the "FC" (File Compare) command and the outcome was that two files matched, a further procedure could be that the batch file be directed to delete one of the duplicate files. Another example of this is given farther on. (See this website's Batch File Tutorial for information on writing batch files.) What do Exit Codes Look Like? Each is one of 256 available values represented by a number from 0 (zero) through 255. `0' typically represents an operation that was completed with no errors. Other numbers might represent problems or various results. Note that not all available numbers will typically be used by a program. In fact, I know of only a few commands or programs that do use all numbers. In addition, there are also those that are programmed to generate random, meaningless numbers upon completion. They only generate one of these at a time but could eventually output all 256 numbers. However, they don't generate different, specific messages, or have designated purposes filling up every one of the 256 slots.
