@Dave Thanks for the refresher! @Phil Something like: set "var=%var:#=$$%" could potentially double a variable in size. And if the variable is over 4095 characters to begin with, it will overflow and cause a fatal error. Is there any way to catch such errors and take remedial action? - SB

Hello All! I was trying to catch errors from overflowing variables (is it possible, btw?) when I noticed the following: @echo off & setlocal enableextensions disabledelayedexpansion :: create variable containing 4k hashes set "hashFile=%tmp%\hashFile.tmp" if not exist "%hashFile%&...

Hello All! In 2008, a Stack Overflow user asked how to echo a newline in Batch files. Someone called Ken posted this answer . This prompted a request for an explanation of how the code worked, but Ken was unforthcoming. So Jeb took up the slack and provided this now famous answer … two and a half ye...

Hi Phil,

I didn’t know you could coax a tab from robocopy like that. Thanks for the tip!

Hello All! Here’s an alternative approach I cobbled together: @echo off & setlocal enableextensions disabledelayedexpansion (call;) title Menu Demo mode con lines=15 cols=20 (set lf=^ %= DO NOT DELETE =% ) set ^"nl=^^^%lf%%lf%^%lf%%lf%^" set ^"\n=^^^%lf%%lf%^%lf%%lf%^^" cls e...

Hi Penpen, Thanks for explaining GOTO’s mysterious behaviour. And you don’t need the body of a FOR loop or an IF block. An unconditional parenthesized block will do. See my previous post for a simplified code example. And you’re right about the ampersand as command separator. I don’t know what I was...

Hi Again! I noticed the GOTO glitch when playing around with the code developed in the Foolproof Counting of Arguments topic. I’ve boiled it down to this: @echo off & setlocal enableextensions disabledelayedexpansion ( goto skip :skip echo(first label ) :skip echo(second label endlocal & got...

Hello All! Interesting discussion. I’d like to add the following observations made while extensions were disabled. The PROMPT command doesn’t work. Neither does: set "prompt=@" Otoh… set prompt=@ does work. And another thing I’ve noticed is that if there are 2 labels with the same name, GO...

Hi Penpen,

That’s perfect! Thanks again.

Hi Penpen,

I’d like to make suspend.exe even more polite!

Please tell me the C# code for returning error level 0 if the program ran successfully, and error level 1 if there was a problem.

Thanks!

Hi All! I borrowed Penpen’s C# Hybrid , transplantedd some code I found in this CodeHill article , and ended up with suspend.cmd: // // >nul 2>nul & @goto main /* :main @echo off & setlocal enableextensions disabledelayedexpansion set "csc=" pushd "%SystemRoot%\Microsoft.NET\F...

Hi Again, Null characters are notoriously difficult to deal with, as discussed in Robust Line Counter . If an input text file is contaminated with null characters, the best course of action is to get rid of them. But if that isn’t possible, there are workarounds. For example, the following snippet a...

Hi Spodermon! Happy Christmas and welcome to the forum. Paste the following (untested) code into an empty Notepad window and save the file as lineNo.cmd: @echo off & setlocal enableextensions disabledelayedexpansion for /f "delims=:" %%A in (' findstr /bilnc:"portshow 0" &quo...
