Re: !mv cmd in qshell not executing

I have successfully set up sftp and am able to run a batch script interactively. I ran into a snag when attempting to run a qshell command from within the script. I've isolated it as follows:

QSH
sftp -v -b /mark/test.sftp user@xxxxxxxxxxxxxxxx


test.sftp contains:
!mv -f /mark/test/* /mark/testarchive

The system response is:

sftp> !mv -f /mark/test/* /mark/testarchive
Usage: mv [-I] [ -d | -e] [-i | -f] [-E{force|ignore|warn}] [--] src target
or: mv [-I] [-d | -e] [-i | -f] [-E{force|ignore|warn}] [--] src1 ... srcN directory
Shell exited with status 1

(Note: Adding a trailing slash or trailing /* doesn't work either.)

Running:
!mv -f /mark/test/* /mark/testarchive
interactively from a logged in sftp session works as expected, but the batch version does not. What am I missing? TIA.
