Does the DIR command allow options to be placed after the file/directory name specifications? It does seem to cause some problems when you put options last at least. In the example below the /b switch is only applied to dir2. C:\temp\test>dir dir1 dir2 /B Volume in drive C is Local Disk Serial number is 60cd:fa66 Directory of C:\temp\test\dir1\* 20.08.2008 9:42 <DIR> . 20.08.2008 9:42 <DIR> .. 20.08.2008 9:42 13 test1 20.08.2008 9:42 13 test2 20.08.2008 9:42 13 test3 39 bytes in 3 files and 2 dirs 12 288 bytes allocated 8 406 994 944 bytes free name1 name2 name3 But when you put it first it is applied to both dir1 and dir2. C:\temp\test>dir /B dir1 dir2 test1 test2 test3 name1 name2 name3 When you read the help entry for DIR it seems to suggest you should put all options before all file names. Sometimes, in batch files and aliases, it would be easier if you could put the options last though.
