openssh unix dev - Feb 2010 - sftp Batchmode command level error suppression does not work?

Hi guys -

OpenSSH sftp  (on solaris)
>From man page
Termination  on  error  can  be suppressed on a command by command basis  by 
prefixing the  command  with  a  `-'  character (for example, -rm /tmp/blah*
).

This does not seem to work - instead the server seems to fail to recognize the
command from the batchfile.

Consider this batchfile
mkdir tmp
cd tmp
put rpt.list
bye

We want to make sure we have a ./tmp dir - if it exists that's ok
We want the ftp to fail if it can't cd tmp

Run as is (second round)
sftp> mkdir tmp
Couldn't create directory: Failure

(which is expected - directory exists)

Run with -mkdir prefix

sftp> -mkdir tmp
Invalid command.
sftp> cd tmp
sftp> put rpt.list
Uploading rpt.list to /home/bboyle/tmp/rpt.list
sftp> bye

Note, the line -mkdir tmp is not recognized as a command

If I change the script to -mkdir xtmp (new dir)

sftp> -mkdir xtmp
Invalid command.
sftp> cd xtmp
Couldn't canonicalise: No such file or directory

Does not mkdir - ignores the entire command
Cd fails (as we would expect)

Any ideas?

Which version of OpenSSH? And are you quite sure it is not Sun's
derivative of OpenSSH? Note also that whether -mkdir is recognized or
not is a function of the client not of the server.
