Re^2: IPC::Run3 error

Confirmed, gnuwin32 provides a dir.EXE, where as dir is a cmd.exe/command.com built-in

$ set IPCRUN3DEBUG=999

$ perl -MIPC::Run3 -e "run3 [qw! C:/PROGRA~1/gnuwin32/bin/dir.EXE /b /
+s /a-d  | cat !], undef,\*STDOUT,\*STDERR"
run3(): running 'C:/PROGRA~1/gnuwin32/bin/dir.EXE' '/b' '/s' '/a-d' '|
+' 'cat'
run3(): redirecting stdout to filehandle 'GLOB(0x9ba4ec)'
binmode STDOUT, :crlf
run3(): redirecting stderr to filehandle 'GLOB(0x9ba52c)'
binmode STDERR, :crlf
C:/PROGRA~1/gnuwin32/bin/dir.EXE: /b: No such file or directory
C:/PROGRA~1/gnuwin32/bin/dir.EXE: /s: No such file or directory
C:/PROGRA~1/gnuwin32/bin/dir.EXE: /a-d: No such file or directory

Ah, so you are using WinXP, it's just that you have a poorly named tool installed. Let me qualify my earlier post. Three problems. You are using options that would be understood by Windows's dir command, which means you're not running Windows's dir command. The `dir` command is a builtin shell command. It can only be run from within a shell. Since you're not running a shell since you're using the multiple argument form of system, the right `dir` will never be found. You're trying to run a shell command (a pipe). Since you're not running a shell since you're using the multiple argument form of system, that's not going to work. You broke up the shell command into bits. How is the shell suppose to execute it? Solution: `$cmd = 'dir /s/b/a-d \| p4 -x - add';` [download] which is short for `$cmd = ['cmd', '/c', 'dir /s/b/a-d \| p4 -x - add'];` [download] Well, it's suppose to be. The latter doesn't work for some reason. Update: Removed extraneous quotes that caused the problem identified in the reply.	[reply] [d/l] [select]

I am not the OP. While system @$cmd will work, run3 will fail with `'""""dir' is not recognized as an internal or external command, operable program or batch file.` [download] even if you hardcode a path to cmd.exe	[reply] [d/l]

Sorry, the double quotes should be there. Typo. Fixed It still doesn't work, though. hum...	[reply]

Yeah, "hum." This is exactly what I was hoping to use run3 for, to run cmd.exe /u /c dir $filespec. It seems that, of the myriad ways that one might attempt to get a glob of Unicode filenames in Perl for Windows, approximately 0% of them work.	[reply]

It seems that, of the myriad ways that one might attempt to get a glob of Unicode filenames in Perl for Windows, approximately 0% of them work. I gave you code that works fine for me here. As I've said twice before, if you show us specifically what is wrong, we'll likely be able to help you fix it.	[reply]

Calling `FindFirstFileW` + `FindNextFile` + `FindClose` (e.g. via FFI::Platypus) works. Aforementioned Win32::LongPath works. Win32::Unicode::Dir works. Changing Perl's Active Code Page to 65001 (by changing its manifest) should make `glob` and `readdir` work.	[reply] [d/l] [select]
