Let's say I have two files, foo.txt and foo.txt~. When I do "dir *.txt", it shows both. Is there any way to tell Windows not to show the one with tilde?

Oh. Miralax, not Ex-Lax.

(some day you'll be old, too)

I think in many or most situations Uncle Bob's second asterisk will take precedence and the tilda will be ignored, and your dir command will feel quite lonely and unloved.

Well, it appears to have to do with the tilda being the 4th character (and falling off into the extended name field). If you try it with files named foo.tx and foo.tx~ or foo.txtt and foo.txtt~ it works just fine.

Can you get the tilda out of the 4th position?

I don't think he wants to delete them, Uncle Bob, although that would make his life easier.

A pipe (that thing the internet is made out of), a grep, and a jug o' happiness.

Pipe the dir output through the find command to NOT find the string ".txt~" or simply "~"
any lines containing the offending string will not be sent to the screen.

dir | find /V ".txt~"

but when I do:

Code:

11/09/2011  16:11               356 astest.c

No ~ entries listed with just "*.c" - I had to use "*.c~" in the first command to be sure the *~ files were listed.

PS of course if you have WinAVR on your machine you have access to "ls" Wink

Yes, ls will do it right.

Dir works right for me if I run it from powershell instead of cmd.

Well, tried ls.exe from WinAVR 20100110. It worked! ls.exe that I normally use, an older version, does not...

EDIT: And "WinAVR-20100110\utils\bin\grep.exe something *.txt" worked too (i.e., does not show stuff from files with tilde). That is why I started this thread in the first place. I guess it is really time for me to upgrade my UnxUtils set.

But I do not think it matters

But you are saying you get a different result with "dir" in XP than I see? As I say if I use "dir *.c" I *only* see files with ".c" as an extension and none with ".c~". Perhaps they fixed it in SP3 (which I use)?

I thought it might be something to do with 3 character extensions rather than 1 character but I get the same with:

Code:

E:\avr>touch test.txt

E:\avr>touch test.txt~

E:\avr>dir *.txt

 Volume in drive E is VBOX_windows

 Volume Serial Number is 0000-0805

 Directory of E:\avr

24/02/2012  11:23                 0 test.txt

               1 File(s)              0 bytes

               0 Dir(s)  240,665,268,224 bytes free

E:\avr>dir *.txt*

 Volume in drive E is VBOX_windows

 Volume Serial Number is 0000-0805

 Directory of E:\avr

24/02/2012  11:23                 0 test.txt~

24/02/2012  11:23                 0 test.txt

               2 File(s)              0 bytes

               0 Dir(s)  240,665,268,224 bytes free

Tried on SP3. No, still see the problem. But then again, perhaps they fixed it in some patches. On the other hand, I think I saw the same thing at work on Windows 7 ... I will double check and report back in an few hours. But WinAVR-20100110's grep.exe works fine, so I am good.

The dir command has the problem on Win7 when it is run from the cmd shell. It is a built in command with this built in "feature".

Powershell implements dir differently and it works right.

Cygwin also has a dir.exe in /bin that works right.

And of course if you are running bash and have dir as an alias for ls, that works right too.

Just checked in case I was using a different "dir" but it sure looks like I'm getting the one in CMD.EXE:

Code:

Cliff, you apparently have the only cmd prompt DIR in existance that works properly. Do you know someone in Redmond?

There are options that can be set in the DIRCMD environment variable, but as far as I know they are the same options you can give on the command line, and I can't find any that make it work right.

One difference I see is you use day/month/year format, but that would be weird if it affected this.

I even booted up ye olde XP SP3 and it doesn't work right. Here's what I got:

Tried on Windows 7. Same issue. Cliff, where did you get your Windows from?

Tried this also:

Code:

#include <stdio.h>

#include <windows.h>

int main(void) {

  static WIN32_FIND_DATA findData;

  HANDLE handle = FindFirstFile("*.txt", &findData);

  if (handle == INVALID_HANDLE_VALUE)

    printf("Error\n");

  else {

    do {

      printf("Name=<%s>\n", findData.cFileName);

    } while (FindNextFile(handle, &findData));

  }

}

Same thing. I.e., it is in Win32 API.
