If you look at the very explicit instructions I originally outlined, you really didn't follow them.
The HELP TQ ATTACH provides several examples of situations that would work.

Meanwhile you typed:

> sim> att tq -f ansi-vms vmst /* the license file */

In this command EVERYTHING beyond the ansi-vms token is considered a list of space or comma delimited file names, or wildcard file names.

In this example, this list would be:
	vmst
	Everything in the / directory
	the
	license
	file
	Everything in the current directory
	The / directory file itself.

The auto tape assembly process that is implemented by this command might treat directory files as binary data, I'm not sure, but trying to pass the / directory and any directories in it as files on a tape is likely a meaningless operation.

Possibly only one of these would be valid (vmst).

You are working on a Linux system which has case sensitive file names, so there is a distinct difference between vmst and VMST.  This command is missing the device name TQ as well...

The simh commands and many of their arguments (ansi-vms and -f) are case insensitive, but filenames are whatever the host system supports.

In the latest commit, I've enriched the error messages issued when unrecognized arguments/files are presented to a tape attach.
