Combine IF statetement with AND/OR

[sambul35]

This Cmd Syntax reference page says, piping commands is possible in IF statements like this:

Code: Select all

IF (... | ...)

Does it actually work in Win 10 Cmd batches? Can you give a working code example?

Is there a similar way in a batch to process AND/OR multiple conditions inside one IF statement instead of repeating IF statements for each condition separately on a new line?


Related, why IF statements don't work when entered on the same line like this:

Code: Select all

IF %var%==s GOTO :test1 || IF %var%==t GOTO :test2

Is there a way to make code more compact and efficient in this case, if there're multiple IF statements?

|| and && are used when you want to conditionally run a second command based on the first command; they have nothing to do with if statements.

command1&&command2 means that you run command2 if command1 returns an errorlevel of 0
command1||command2 means that you run command2 if command1 does not return an errorlevel of 0


And to answer your question, if you surround both if statements with parentheses, you can use a single & to join them.

Code: Select all

(if "%var%"=="s" (goto :test1))&(if "%var%"=="t" (goto :test2))

Are you saying there's no way to combine single IF with AND/OR in a batch?

Can someone give a working example of a single IF (... | ...) piping statement?
