Yet another method for debugging large scripts, that I use a lot, both at home and at work, to debug very large batch files: Use the debugging routines and macros in my Library.bat batch library. This works by instrumenting the problematic code, with macros defined in Library.bat. These macros do no...

What you need is a (for /f ...) command. Ex:

@aGerman: Hi Steffen, There's an important difference between your %\n% macro and mine. (Beyond the fact that I generated mine with an overly complex sequence) Mine expands to <LF>^ Yours expands to ^<LF> Obviously both work for generating a one-line batch command, which in turn creates a multi-line...

The # comment does not work the way you did, because it's a line comment, and the PowerShell command you generated was all on one line for PowerShell. To use such a line comment, you need to generate a PowerShell script that contains multiple lines. This is akin to what we do for generating multi-li...

surely an external command can read a binary file redirected to stdin. This is deviating way off the main topic of this thread, but yes, this is a problem. (Here we're talking about programs that eat/produce/filter text, not binary data like sound or images.) I tried many things, then ended up usin...

Hi Dave pipes do not in and of themselves do any type of transformation. You're splitting hairs! OK, it's not actually the pipe that does the transformation, it's the batch interpreter that does it before passing the data to the pipe. In practice, the effect is the same: Any pipe in a batch involves...

Is your console using code page 65001? This script uses sub-commands and pipes internally. Any text that is piped from one application to another, or passed as an argument to a sub-command, is converted to the console code page for that. So if your code page does not include Chinese characters, they...

Hello, Try using subroutines :jdate and :jdate2date from this very site library of functions: https://www.dostips.com/DtCodeCmdLib.php#Function.jdate Ex: call :jdate TODAY &:# Get today's day number set /a "YESTERDAY=TODAY-1" &:# Get yesterday's day number call :jdate2date YESTERDAY YEAR MONTH DAY &...

I was not aware it was possible to do one-line HTML applications like this. Nice! If you don't find a native HTA way, maybe it'd be possible to return the user choice number as the HTML Application exit code, then send that to the clipboard using an outside tool? There's an example on how to return ...

For every line you'd need to do some complex manipulation, like: WriteLine > PingLog2.txt type PingLog.txt >> PingLog2.txt del PingLog.txt ren PingLog2.txt PingLog2.txt Is this worth it? Instead, I suggest that you consider using a Windows port of the Unix tail tool. For example get tail.exe from Un...

Same for me: - Crashes on company-managed computer with Windows 10.0.16299.1625 - Works fine on another one managed by me, with Windows 10.0.19041.84 On the system that crashes, there's an error saying "Console Window Host has stopped working." So apparently the problem is with conhost.exe, not with...

This works great indeed!

Now, what would be very nice is to find a way to redirect stdin/stdout/stderr from the elevated shell, back into the original shell.
(Like Unix' sudo does!)

This is due to the way the child cmd.exe instance processes double quotes on its command line. (And it does not matter if that child instance is invoked using single quotes ' or back ticks `.) Extract from the cmd /? help screen : 1. If all of the following conditions are met, then quote characters ...

The list of tasks running in Windows is very long, and keeps changing all the time. Even if you don't start or stop anything yourself. It'll be much more reliable to filter lists before comparing them. Also, wait for a while before getting the second list, to give time to Firefox to start. @echo off...

The correct syntax is:
