![]() Use the option, cmd.exe /e:off to disable command extensions.Set the DWORD registry key HKCU\Software\Microsoft\Command Processor\EnableExtensionsCommand to 0.Although the goto command is built-in to cmd.exe, the special label :eof is known as a command extension.Ĭommand extensions can actually be disabled, via the following methods: cmd.exe has both internal and external commands. You may have noticed that the previous examples used extensive use of the :eof label. Command Extensions and the :eof Special Label From that point forward, the script executes line-by-line.īatch file is running the subroutine Special Cases, Bugs, and GOTO Statement Considerations!Īs with any command, there are special cases, bugs, and important considerations to keep in mind while using the goto statement in your code. The first echo command is never run as the batch script jumps to the specified goto command. The goto command changes the flow of the batch script. When you run the below script, you’ll see that the batch script runs the code in the order that you have the GOTO commands. If you simply use GOTO eof, without the colon, the batch script looks for the label of :eof somewhere in the file and does not jump to the end and return! ![]() An optional goto:eof command that tells the batch script to finish or jump to the end of the file ( eof).Comments that start with :: to indicate the code is not executable.The goto labels created by starting with a colon with code underneath called run_first.To do that, you’ll use the GOTO command combined with a label. Instead, you can redirect the batch file with the goto command. You could cut and paste but for a real batch file, this might not be possible. Now, perhaps, you’d like to run the third line before the second line.
