Re: why IPC::Open3 can't execute MS-DOS "dir" command?

Very likely because dir isn't actually a command in and of itself, but is a built-in command of cmd.exe

Change "dir * \/b\/s" to be "cmd /C dir * \/b\/s"

You also shouldn't call subroutines with the & prefix, unless you know the behaviour that implies

Change "dir * \/b\/s" to be "cmd /C dir * \/b\/s" Seems it can't work, got the following error: `Execute Command: cmd /c dir * /b/s [ERROR] (1) : Parameter format not correct - "s"".` [download] And if I remove the parameters "/b/s" it stopped again.	[reply] [d/l]
