With DelayedExpansion it's safe with all character, but then you don't need the FOR /F

Hi Saso, not quite strange, it's the expected behavior. The rule is: If a redirection to a stream is found, store it in a buffer (one buffer for each stream), remove the redirection text from the command line. What same mean? Some examples @echo off del /s test.txt 2> NUL > NUL @echo on echo Test1>>...

As you have already observed, GOTO breaks any loop, it can't be used for continue, but for break. For CONTINUE, in most cases I would recommend an IF block instead. FOR /L (1 1 10) DO ( if someCondition ( echo DoWork ) ELSE ( DoNothing ) ) If your code is very complex/long you could use GOTO's for t...

It's always a good idea to use the safe SET-Syntax.
This is safe against trailing white spaces and additionally it avoid problems with special characters

The extra space is indirectly generated by the pipe operation. To use the pipe, cmd.exe converts the expressions on both sides. Obviously this is hard to debug, but with the magic cmdcmdline variable it can be done. @echo off ( echo This is echo a test echo %%cmdcmdline%% <nul set /p .=Output) | fin...

Okay, I shouldn't write when I'm tired

I completely missed the ELSE part of your code.
Your definition looks simpler and better than mine, I don't know why I didn't found it myself

Shouldn't the following work just fine, then? If the only requirement is that the parser has to stop on the first character after the empty line, then & fits this requirement perfectly: if "%=^%=" == "%=%=" ( set ^"\p=%%<nul" set ^"\n=^^^ %= These lines are supposed to be undented and empty; =% %= ...

This should work IF "" == "%$for:param=3%" echo arg3 is empty You test against command line arguments, but you should test against macro FOR-Parameters instead, there the %%3 is a safe parameter. But my set "\n=^" definition for the command line context is weak, it doesn't support multi line blocks ...

Regarding the definition - actually I've took it straight out of your library - I also can't think of anything that would incline user input. (It doesn't hurt to have it, though...?) I criticized my own code, that's hard :D The <NUL doesn't harm, but it's still superfluous . Notably I find a need t...

I've just whipped up a macro to do exactly that (taking ideas from your repo yet again, lol): I am glad to hear that someone is looking at my library at all :D Actually, instead of double percent expansion, could replacement syntax work? Similar to what you've done with for-parameters in your libra...

It's stupid simple :D The problem is the CALL not your function. call echo #1 ^^ call echo #2 ^^^^ call echo #3 "^^" call echo #4 "^^^^" call call echo #5 "^^^^" call call call echo #6 "^^^^" #1 ^ #2 ^^ #3 "^^^^" #4 "^^^^^^^^" #5 "^^^^^^^^^^^^^^^^" #6 "^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^" It's tricky t...

Hi dtmenges,

I guess you called your batch file "timeout.bat"?
Think a bit about the name

To replace an exclamation mark, the only way is to use the percent replace syntax, but as we are already in a code block, percent expansion doesn't work, so ...

I reviewed the ANSI escape codes and found no way to generate an ENTER char. Indeed, there is no way to generate nothing other than the cursor position You look at the wrong site, I found at least ESC Z Send VT100 Identification String ESC [ c Send VT100 Identification String ESC [ x (V) Send Termi...
