Bug with %%~sA resolved foxidrive 3/19/04 2:19 AM

You know the bug when using %%~sa to resolve a filename to the short path
which returns more than just the short filename?  It is kinda erratic but
as example is as follows, with %%~sa and followed by %%~fa

D:\TEMPFO~1\0_3_BI~1.JPGg name\0=3=biz.jpg
D:\tempfolder with a long name\0=3=biz.jpg

After encountering it again I (re?)discovered that running command.com in
the batch file forces %%~sa to return the correct name - but it breaks
%%~fa.

It's an oddity, perhaps useful in some situations, but there you go.


@echo off
md "tempfolder with a long name"
cd "tempfolder with a long name"
type nul>"0=3=biz.jpg"
:: type nul>"0 test.jpg"
echo Short name (with bug) and longname
call :test
echo.
echo.running command.com
command /c rem
echo.exiting from command.com
echo.
echo Short name corrected and longname (with path bug)
call :test
cd ..
echo.
pause
rd /s /q "tempfolder with a long name"
goto :EOF
:test
for %%a in (0*.*) do echo %%~sa &echo %%~fa


While searching google groups for previous messages concerning the short
name bug I came across this message from Walter Zackery, Subject: Windows
NT tricks, traps and undocumented features, which I found interesting
reading from 'history'.  URL is on one line.

People who use command delimiters in filenames for use at the command
prompt instead of just in the GUI deserve all the weird behavior they
find.  The commented out file creation of a valid name file indicates
you were fully aware that the problem was with the highly questionable
file name you actually used.

I think this bug may be serious.
The odd example filenames were made by Mr.foxidrive to explain the bug,
so some people may think that bug does not appear in real situation.

But I have a file "C:\Program Files\Common Files\System\Ole DB\msdadc.dll"
in my WinXPhome+Office2K, and another a lot of similar files.

@echo off
for %%A in ("C:\Program Files\Common Files\System\Ole DB\msdadc.dll") do (
echo %%~fA&echo %%~sA)

Results is:
C:\Program Files\Common Files\System\Ole DB\msdadc.dll
C:\PROGRA~1\COMMON~1\System\OLEDB~1\msdadc.dlldll

Of cource I don't think this bug raise errors in ordinary use of Windows,
but the bug may appear in custom made BAT/CMD scripts.

I think this is a *feature* not a bug.

Befor running command.com, current directory is
"C:\work\tempfolder with a long name"
After running command.com, current directory is
"C:\work\TEMPFO~1"

The description of %~fI in for/? is
"expands %I to a fully qualified path name"
I think Microsoft will say "It does not assure that %~fI is always LFN".

Add PUSHD and POPD to your example, then the result is same befor COMMAND.COM.

If I understand foxidrive correctly, the bug with %%sA only occurs in

Tood, both bugs are in CMD.EXE but are modified by the mere launching of
COMMAND.COM in the batch file.

Tood, both bugs make themselves felt in CMD.EXE but are modified by the


mere launching of COMMAND.COM in the batch file.

foxidrive, I follow you now, thanks. Unfortunately, I use Win95cmd in Win98
so the pushd/popd trick has no effect on my system. Although, Win98's
command.com returns 8.3 names correctly, I'm studying the %~s1 bug for
future reference.

OK try this. The idea is to break up the LFN into its path/file
components and convert each separately. It's a bit more complex when
you have to also get the filename as a SFN.

Dividing the LFN into only 2parts (path/file) is not enough.
We must convert each element of the LFN separately.

This works well. (Fortunately I have D: drive.)
Output is:

[d:\TEMPFO~1\ATEST~1.JPG]

But it's too heavy to get only a short name.
May MS fix this bug in the next SP?

Yes, you're right. Although I could get the above path to work, I was
unable to get a correct result if the path was sufficiently devious.

So I went back to your original suggestion of using Command.com. By
quarantining Command.com within a FOR process, you can get the correct
result without breaking %%~fa.

@echo off

set lfn="\tempfolder with a long name\sp\l p\a test.txt"

I adapted this - but I still have a glitch to iron out.

I just wanted to say thanks, and to Garry as well.  My interest in this is
not just academic...  I use Qbasic in many tools and need to open long
filenames for reading.  As Qbasic predates long filenames I need the short
path\filename - so there is a practical application for me.

That'd be nice, but seeing how the bug has been around so long it seems
unlikely.

Have you tried extracting the sfn from DIR/X? It would require walking the
path back to the root. Unfortunately, FOR/F does not work in Win95cmd as far
as parsing file contents goes, so I can not provide you a working example.

I have to go now, but I could offer some air code tomorrow. ?

Thank for the suggestion - I've looked at that but in their wisdom MS have
implemented a routine for dir /x that only prints the short filename in the
screen position if it is a long filename.  That would entail even more code
to get all the filenames.

But I can happily report that I have two routines which appear to handle
all filenames.  I'll post them below.

This is based on OOTANI TAKASHI's code, and takes 60 seconds on 2,800
files, but is quite convoluted.

@echo off
type nul>temp.tmp
echo generating file list...
for /f "delims=" %%a in ('dir *.gif /b /on') do (
echo %%~fa>>temp.tmp
call :sfnsub "%%~fa"
)
for /f "delims=" %%a in ('dir *.jpg /b /on') do (
echo %%~fa>>temp.tmp
call :sfnsub "%%~fa"
)
goto :EOF
:sfnsub
set var=%*
set var=%var:\=\" "%
set sfn=
call :loop %var%
goto :EOF
:loop


for %%A in ("%sfn%%~1") do set sfn=%%~sA
shift
if not "%~1"=="" goto :loop
set "sfn2=%sfn:&=^&%"
echo/%sfn2%>>temp.tmp
if not exist "%sfn%" echo %sfn% doesn't exist
goto :EOF

This is based on using command.com within pushd/popd commands and takes 70
seconds on the same 2,800 files.

@echo off
type nul>temp.tmp
echo generating file list...
for /f "delims=" %%a in ('dir *.gif /b /on') do (
echo %%~fa>>temp.tmp
call :sfnloop "%%~fa"
)
for /f "delims=" %%a in ('dir *.jpg /b /on') do (
echo %%~fa>>temp.tmp
call :sfnloop "%%~fa"
)
goto :EOF
:sfnloop
pushd .
command /c rem
for %%b in ("%~1") do echo %%~sa>>temp.tmp
popd
goto :EOF

To Garry, your last solution worked fine and is between the two solutions
above in complexity.

Yes, but is that not what we enjoy doing? ;-)

BTW, did you know there *are* LFN to SFN routines for qbasic?

I hadn't ever thought to look for any - but did find some, and related

Well, almost all filenames... after some more use I found an exception, but
I don't blame the routines for the failure coz it is probably due more to
the mishandling of accented characters.

I had a filename containing an "ã" character (not sure how it'll display,
it's an "a" with ~ above it) and both routines returned a short path with a
long filename (with the accented "ã" replaced with a normal hex 61 "a"
character).
 
Just thought I'd update the thread...

Yes, I made mistake, I had not tested special chars only space and = when last posted.
Always special characters cause troubles.
I think these lines are a little better than above.
  set "sfn=%sfn:&=^&%"
  set "sfn=%sfn:^^=^%"
  echo/%sfn%>>temp.tmp


  if not exist %sfn% echo %sfn% doesn't exist
  goto :EOF
But this still does not work well for filenames containing %,
because it isn't passed to subroutine.

This subroutine does not work for general case.
The effect of "command /c rem" is only convert current directory name
from LFN to SFN. So it must CD to target directory.
  :sfnloop
  pushd .
  cd /d "%~dp1"
  command /c rem
  for %%b in ("%~nx1") do echo %%~sb>>temp.tmp
  popd
  goto :EOF
But this does not work well for filenames containing ^ not only % .


BTW, I don't like the welcome message of command.com appear on the screen
when it run on cmd.exe at the first time. Are there any TIPs suppress it?

It works well enough for me, but it'd be nice if MS ploughed some R&D into
fixing and enhancing cmd.exe

This doesn't occur on my PC...

Indeed I don't have no file its name contains ^ in my PC but for testing.
But there are some files those name contain % in my PC.
It may come from why % is used for showing spacial characters as hexadecimal.
 e.g. http://somewhere/%7Emy/A%3DB.html
Files under "Temporary Internet Files" may not be important.
I have a few % files in Basilisk(Mac emulator on WIN) directories.
Anyway they are minority. I also give up here.

I see. I've found.
It must be effect of IME (that enables us to input Japanese charactors).
I'll check it, thank you.
