    I'm getting the "Select: invalid argument" error with the above commands
    also, but the transfer does work so I guess that error has nothing to
    do with the problem.

    Some more testing has revealed this

    ssh linuxhost 'cat parseshell/price.prn' >> /path_on_sco/dtnprice.prn

    The above works on the command line. If I use the -n option on the
    command line then /path_on_sco/dtnprice.prn is an empty file after
    running the command.

    ssh -n linuxhost 'cat parseshell/price.prn' >> /path_on_sco/dtnprice.prn

    The -n option on ssh prevents reading from stdin. Now when cron runs the
    script it doesn't matter if I used the -n option or not stdin is not read.
    I think for this command to work I need stdin to be read so I guess it
    just won't work with cron?
