Displays ALL files in the current directory, including hidden and system files.

Undocumented, but often used by advanced users, when no file manager is at hand.

the comma apparently has a wider meaning in MS-DOS:

"DIR *.COM," displays all COM files, but NOT hidden ones.

"tree," works as "tree"

"tree,C:\" fails with an error "Too many parameters"

"copy autoexec.bat,backup.bat" copies autoexec.bat to backup.bat

Do you know what the exact rules are?

"dir.com" does the same. Or "dir.bat" for all .bat files, ...

"tree," works as "tree" "tree,C:\" fails with an error "Too many parameters" "copy autoexec.bat,backup.bat" copies autoexec.bat to backup.bat

Um. Didn't know that. "copy autoexec.bat:backup.bat" works too.

There also is copy autoexec.bat+,, to update a file's timestamp (aka. poor man's touch).

It doesn't work in SvarCOM. SvarCOM tells me:

,, - File not found
1 file(s) copied

But the timestamp is not updated.

No. (Most of)These are probably quirks. Some are documented in http://www.retroarchive.org/garbo/pc/batchutil/muf17.zip and / or http://www.retroarchive.org/garbo/pc/batchutil/batfaq23.zip
