I have a question about if - else structure in a batch file. Each command runs individually, but I couldn't use "if - else" blocks safely so these parts of my programme doesn't work. How ...
In addition to %G in a for loop, %1 is also allowed. %% is needed in a script to avoid ambiguities. "When working at the command line (not in a batch script) there is no possibility of any batch file parameters %1, %2 etc so the logic above is not followed and hence FOR parameters on the command line only need a single %." See details.
The batch size should pretty much be as large as possible without exceeding memory. The only other reason to limit batch size is that if you concurrently fetch the next batch and train the model on the current batch, you may be wasting time fetching the next batch (because it's so large and the memory allocation may take a significant amount of time) when the model has finished fitting to the ...
Addendum - This is a duplicate question with nearly identical answers to Using an OR in an IF statement WinXP Batch Script Final addendum - I almost forgot my favorite technique to test if a variable is any one of a list of case insensitive values.
FOR %%A IN (list) DO command parameters list is a list of any elements, separated by either spaces, commas or semicolons. command can be any internal or external command, batch file or even - in OS/2 and NT - a list of commands parameters contains the command line parameters for command. In this example, command will be executed once for every element in list, using parameters if specified. A ...
It's the same as 'if "%1" == "" goto somewhere', except that will fail in batch files, because "" evaluates to nothing and the whole sentence reduces to 'if %1 == goto somewhere'. I prefer X, since ! makes you think it's a special operator, whereas it's just used as an extra character to overcome the problem with an empty string.
I'm feeling quite dumb right now, as I'm attempting to code a big long program in batch, and I just discovered how little I actually know about the language. One thing I've seen in many suggested solutions are commands such as set, and then /p or something similar.
I need to execute a command 100-200 times, and so far my research indicates that I would either have to copy/paste 100 copies of this command, OR use a for loop, but the for loop expects a list of ...
If you double-click the batch file %0 will be surrounded by quotes. For example, if you save this file as c:\test.bat: @echo %0 @pause Double-clicking it will open a new command prompt with output: "C:\test.bat" But if you first open a command prompt and call it directly from that command prompt, %0 will refer to whatever you've typed.
