@npocmaka_: Welcome to DosTips! @Squashman: You’re absolutely right, as usual. I overlooked this line: SET "z1=%~z1" Dave had said previously that one solution would be to use delayed expansion, so I made a link where there was none and confused !1z! in Endoro’s snippet with the erroneous ...

@Endoro: Thanks for the revised code! It never occurred to me that parameters could be referred to as “!~z1!” using delayed expansion. I don’t remember seeing it used before. I’ve seen “!%~1!”plenty of times, but that’s a whole other box of crayons. @Dave: Thanks for the great explanation. It makes ...

Hi Taripo! DOS 6.22 programs should run without any problems under Windows 98, or am I missing something? If you’re trying to execute an old DOS program under XP or higher, try right-clicking on it, selecting Properties from the pop-up menu, and click on the Compatibility tab… although I doubt if th...

Hi Alan!

Wow! I didn’t understand a word of that. Sounds like the kind of thing Fred Langa of Windows Secrets fame would sink his teeth into. Or have you solved the problem on your own in the meantime? Don’t leave us hanging in suspense!

Hi KidHaxMan!

What did you type into Google? I just tried “microsoft forefront command line” and got lots of promising results.

Good luck!

Hello Rookie! Just noticed your post in the list of unanswered topics. You probably didn’t get any replies because you weren’t specific enough. Are the two files you wish to merge text files? Could you give a sample of both? And how do you want them merged? One after the other, or side by side? - SB

Dear DosTips, Please peruse the following snippet: if "%~1" neq "" ( if %~z1 equ 0 ( echo(file is empty ) else echo(file is not empty ) else echo(no cmdline args found If a filename is supplied on the command line, all is well. But if no filename is specified, the program throws ...

Thanks Dave! The scary thing is that I actually understood your explanation. Another little piece of the puzzle has fallen into place. Anyways, for anyone still reading this topic, to make the LF variable work inside the for /f loop’s in (…) clause using delayed expansion, you would have to do the f...

Hello All! The little snippet below outputs the number and contents of any lines found in a user-specified file that don’t contain a Line Feed. And then it does it again. First using a bare findstr, and then using findstr wrapped inside a for /f loop’s in (…) clause. @echo off & setlocal enablee...

Dear DosTips, I tried piping a single character into findstr using set /p, type, and findstr itself. The results were the same: absolutely nothing! findstr silently gobbled it up. > <nul set /p "=#" | findstr /n "^" (no output) > <nul set /p "=##" | findstr /n "^&q...

Hello All! Apologies for my late arrival to this topic. I hope it goes better than the last time I tried to revive an old thread! Anyways, Allal makes a valid point. However, there is a Batch solution to Bouchta’s problem. The following little program accepts a filename as argument and runs findstr ...

Hello All! Sometimes I’d like to snip off the newline from the end of a file. But there’s no efficient way to do it using pure Batch commands. Recently, I unearthed a Super User question on how to truncate a set amount of bytes from a file . The second answer gave a PowerShell solution. I know nothi...

Hello Jeb! Only found this earlier topic today. But my question still stands: I’m looking for a robust method to check for redirected input (ie, prog.cmd < file.txt). The program in the OP correctly identifies redirected input from a file. But like FPW says in the comments, it’s fragile, requires a ...

Dammit, Foxi. You’re right. If a colon comes after a null character on a line of output from findstr /n "^" "%~1", find /c ":" will count it as two lines. That torpedos Ranguna173’s otherwise elegant solution. As to your second point, try this (note the null character o...
