Oops! I checked and find can output Unicode and findstr can't. But find is no good either because it appends CR+LF to output. Sorry about that... Can type work with Unicode files from a cmd /u subshell? I seem to recall some discussion about this before, but of course I can't remember when or where....

Hi Jeb and welcome back. Brilliant workaround for the "echo without linefeed" problem. Wish I'd thought of it! I had thought of using copy /a, but I didn't know how to get rid of the CtrlZ at eof. Never occurred to me to combine it with the /b switch for the destination file. One tiny sugg...

Hi Again! I've written a program to copy a line from a text file and save it to a new file. It uses more, findstr, and temporary files to do the heavy lifting so it should work for lines >8191 characters. I won't include the program here because much of the code is similar to my previous effort. But...

Hello All! I have the following block of code in my win2unix program: setlocal enabledelayedexpansion if "%~1"=="" (if /i "!cmdcmdline!"=="!cmdcmdline:%~n0=!" ( endlocal & goto usage)) else ( if /i "!cmdcmdline!" neq "!cmdcmdline:%~n0=!"...

Hi Everyone! Since Christmas is a time for nostalgia, I thought I'd remind you about Elf Bowling. It was first released by NVision Design back in November, 1999. It instantly went viral and many sequels followed. But the original is surprisingly difficult to get hold of... until now! There's a link ...

Hi Carlos! I have learnt the hard way not to bother Liviu until he's had his morning coffee See Jeb's answer in this SO thread for an example of safe string return. And once you've absorbed that , you can try bending your mind around Dave Benham's Macros with Arguments . Dave says you can wrap any f...

Hi Raam! Welcome to DosTips. Maybe something like this might help... findstr /bl ^"\"%~1\"^" Remember that the dot (.) in the IP address is a findstr metacharacter and should either be escaped with a backslash (\) or turned off with findstr's /l (literal) switch. Also, I'm guessi...

Thanks Ed!

That's what I thought.

Will file that link away for future reference.

Btw, who broke the bad news about more's 64k line limit? Does anyone have a link for that? I like to cite references in my blog posts whenever practicable.

@Ed and @Mic: Well, I suppose if we had bigfile.txt and we wanted to isolate the 100th line in its own file, we could try the following from the command line: more +99 bigfile.txt | findstr /n $ | findstr /b "1:" ^ | (pause>nul&pause>nul&findstr $ >line100.txt) Should work with lon...

Hello All! A little program that accepts a line number, a filename, and an optional variable name from the command line and stores the contents of the line from the file in the variable (uses NTHLINE if none specified). @echo off & setlocal enableextensions set "a2z=abcdefghijklmnopqrstuvwx...

Thanks for enlightening me, Liviu!

And apologies for saying your code would choke on control characters. I don't know why I thought that. Maybe if I read first and typed later...

Hi Boombox! Have you tried Best Free Windows Narrator Voices ? Some good links there. There are also rumours that ETI Eloquence voices can be made to work with NVDA (an open source screen reader for Windows), but it's legally murky and I couldn't possibly comment further... On a lighter note, you mi...

Hello All! Everyone knows this old trick of converting Unix text files to Windows format: more unix.txt > win.txt Btw, more waits for keypress after scrolling 65,534 lines no matter what. But going the other way (from Windows to Unix) is less straightforward. But with a little chicanery and a lot of...

Classic newbie error. But when I went back to add the code tags, someone had beaten me to it. Thanks, whoever you are! Anyways, I wrote the program to see if I could exploit findstr /o ^^. I acknowledge that it is grossly inefficient, case insensitive, and that it will choke on ~, =, and *. But the...

Hello All! Sorry for the late arrival. What did I miss? Anyways, I've cranked out a little program similar to Liviu's. Only my effort counts the occurrences of the substring in the source string and creates a 0-based index list of the position of each occurrence. @echo off & setlocal enableexten...
