Bat file scripting if

Wouldn't an echo to findstr be an option? The answer is wrong. I don't think so. Yeah as far as I can tell those two are the only option.

But just needed to do a small bug fix to a batch script and wanted to know if this was possible. I'm picky when it comes to clean code lol — Anthony Miller. Correct English would read "Didn't find it". I was going to edit the question, but did find that someone has already done it, then did found that it got rolled back.

How come this never made it as the recommended answer? I don't know, upvoting in general is a very strange process and dubious? But in this case, I guess it's timing. The question is quite old and my answer vere recent. Anyway, we must be happy when we can find any answer that works.

One possible drawback with this technique although I like the out-of-the-boxness of the approach! Theoretically, yes. But I have created hundreds of batch files, I use dozens of them everyday and I never met such a case. So let's stay in practice! I have such a case today where I don't want to execute the condition twice. I want to do something if either file a or file b exists. Show 1 more comment.

The answer is great — Alex from Jitbit. But there is no simple way to do that in batch. That is why a temporary helper variable is often used.

Even if this question is a little older: If you want to use if cond1 or cond 2 - you should not use complicated loops or stuff like that. GOTO end :doit echo "doing it" :end Without goto but an "inplace" action, you might execute the action 3 times, if ALL conditions are matching.

Andrew Rasmussen Andrew Rasmussen It's possible to use a function, which evaluates the OR logic and returns a single value. The goal can be achieved by using IFs indirectly.

Simple example Each block is resolved to true i. That's for checking if multiple variables equal value. Here's for either variable. I could compact it more. Never got exist to work. Never got batch files to work above Windows XP. Note that each drive has a different current folder, and it is "remembered" even if that drive is not your current working directory.

Compo Using SET without parameters allows for different variables, e. Your variable, and that of the OP, is specifically named var. When we execute the batch script file over the command prompt, all the command get executed one by one by following the sequence written in the batch file.

Lets save this batch file as test. Comments are very useful to write a description for the command in a large batch file which contains any number of command and reference of another batch file; it makes the batch file easy to understand and modifiable. This will run java demo jar file, just navigate to your java maven base directory and run this batch file. This batch file will run each of the files which belong to package, test, and deployment respectively; as a separate manageable process and will open a new console to log a command output for each of the batch file.

The batch file was a very popular solution to executing a series of command one by one when DOS used to be a very popular operating system, Nowadays also batch script plays a very important role in various tasks such as to automate the configuration of the windows server or to schedule a task.
