One more observation. As you already said, the scan for labels is reset at the file beginning or after a CR/LF. The label scanner reads chunks of ~512 bytes, therefore we see the described effect. BUT the scanner is able to set the new file position to the wrong position after a label is found :!: @...

Thanks Dave, your findings are impressive :D. I didn't see the idea of relative counting the characters :( I played with a file with unix style endings and a single CR/LF and thought the problem was gone as I didn't see the reset behaviour. But your analysis is really good. And your rule is really s...

Hi jfl, like Dave I'm very interessted. And I simplified your code to a minimal, failing example: @echo off goto :zwei :####################################################################################################################################################################################...

Hi jfl, nice work! Eventually I found a heuristic that seems to give good results: - If the first token is == %COMSPEC% without quotes, then this is a for /f, and I should not run AutoRun scripts. - If the second token is /c, then this a manual execution of a single command, and it's not worth runni...

Hi bosekamineni, you should use delayed expansion, because it's always safe to expand with delayed expansion. @echo off setlocal EnableDelayedExpansion set "_string=Test String With | &&<> command" echo the string is !_string! The only drawback is that you be careful with literal exclamation marks, ...

Hi siberia-man, - It is reliable to detect an invocation from FOR/F. - Invokations from pipes doesn't trigger the autostart at all. - When a new instance of cmd.exe is launched directly it can fail, as it's possible to add any possible parameter, but then it only drops the additional commands. It sh...

Hi, I'm using the registry key to start a batch file, that adds some doskey macros. BUT it's a bit tricky, as the batch file will also be called for new cmd instances inovked by FOR /F :!: If the batch file doesn't check that, you can get really strange behaviour in all of your batch files. Think of...

Hi jfl, interesting :) I tried to build a simple workaround history.bat @echo off doskey /history | findstr /n "^" It works as expected 1:doskey /history 2:echo test 3:npp hist.bat 4:hist .. and I thought that the output of the findstr should work normal, but ... history.bat | more Still outputs not...

Hi Dave, I tested your code Windows 7 x64: 4096 Windows XP x32: 4096, but FINDSTR doesn't work reliable And I retested the blocking limit of pipe blocks. First a testString of the configured size is send. The a "second line" is send. If the blocking is active the second line is send only when thread...

Hi Andreas, I suppose there is more in your batch file, because I just tested this sample batch file in a directory named "C:\temp\amp & ersand\" and it works @echo off setlocal EnableDelayedExpansion echo cmdcmdline: !cmdcmdline! start "Firefox" "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" ...

Hi siberia-man, I currently can't follow Aacini's technic :?: , but it looks impressive ( I have to spend more time on this). But I can answer your question. A quite exciting technique for scripting batch macros. One this I can't understand. When you code the beginning of any macro you use something...

Hi J'aitreschaud, ESC[ <n> m is the Select Graphic Rendition sequence, it sets the display attributes, they affect each NEW character that will be written, that's all. In your case, it changes the complete background after the cls, as the complete screen will be filled with spaces. To reset that set...

Hi pieh-ejdsch, Then with a double circumflex final. The parameters are passed into the :Sub but with circumflex at the end these parameters expand to a rat tail. The caret/circumflex will be doubled always by a CALL command, normally this isn't visible, as the doubled carets are used as escape char...

Hi,
