    What you have above works on the command line, but cron doesn't like it.
    Cron gives me the same error "select: Invalid argument" an empty file is
    appended to /path_on_sco/price.prn, but it's not getting the data from
    the cat command run on the Linux box.

    I can get it to work using the three commands below, but it would be nice
    to do it in just one command like you have above.

    #!/bin/sh
    scp linuxhost:parseshell/price.prn price.prn
    cat price.prn >> /path_on_sco/dtnprice.prn
    ssh linuxhost 'rm parseshell/price.prn'
