Ambiguous output redirect in xterm
Hi all,

I've been working on a bash script to help with backups that I have to do at work.

One of the lines in the script is supposed to launch an xterm, log into a specific server node and launch a tar backup to tape. This part works ok, but I've been trying to get stdout and stderr to display in the xterm and output to a log file using tee.

To this end, this is my current code:
Code:
xterm -hold -e "rsh amaqc01 tar -cvML471859200 -f amatap0"$tape_nd":/dev/st"$tape_dr" /dir1/dir2 2>&1 | foo/bar.txt" &

When the script launches this though, the xterm presents an 'Ambiguous output redirect' error.

I suspect that this is actually due to the system using csh as the default shell such that the xterm is actually running csh rather than bash.

I've tried
Code:
xterm -hold -e "bash; rsh amaqc01"

to fix this but this seems to end up opening the xterm, running the rsh and THEN running bash.

So I guess my question is, what am I missing? Is it even possible to achieve what I'm trying and if so, how?

Thanks in advance

gst-complete

gst-complete-0.8(1)						   User Commands					       gst-complete-0.8(1)

NAME

       gst-complete-0.8, gst-complete - perform bash completion for gst-launch command lines

SYNOPSIS

       complete -Cgst-complete-0.8 gst-launch

       gst-complete [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-complete-0.8 enables bash to provide context-sensitive tab completion for gst-launch command lines. See gst-launch(1) for the syntax of
       gst-launch command lines.

       You must have a version of bash that supports programmable completion. Such versions of bash provide the complete built-in command.

       gst-complete is a wrapper script that runs the latest installed version of gst-complete-X.X. For example, if both gst-complete-0.7 and gst-
       complete-0.8 are installed on your system, gst-complete runs gst-complete-0.8.

OPTIONS

       The following options are supported by gst-complete-0.8 and gst-complete:

       --help	       Display detailed usage message. You can also use -? to specify this option.

       The following options are supported by gst-complete only:

       --gst-list-mm   List found major/minor versions. This option displays the versions that are available.

       --gst-mm=string Force  major/minor  version.  This  option  enables you to specify a specific version to run, if you do not want to run the
		       default version.

       --print	       Print wrapped command line. This option displays the command that will be run, and then runs the command.

EXAMPLES

       Example 1: Generating the Registry of Available Plugins by Running gst-compprep

       Run the following command in your .bash_profile or other appropriate place:

       example% complete -C gst-complete-0.8 gst-launch

       Example 2: Running the Wrapper Script and Displaying the Command Name

       example% gst-complete --print
       /usr/bin/gst-complete-0.8

FILES

       The following files are used by this application:

       /usr/bin/gst-complete-0.Executable for bash completion for gst-launch

       /usr/bin/gst-complete   Wrapper script that runs the latest installed version of gst-complete-X.X
