Most of the stuff you can do in Spacewalk webui you are also able to achieve
with Spacewalk's XML-RPC API (i.e. you don't need your browser, but you're
able to write set of scripts which will automate whatever you'd otherwise
be doing manually clicking in webui).

So just as you're able to schedule a remote command in the webui, you're able
to do it with a xml-rpc script. Webui in Spacewalk 2.1 won't accept >< signs,
but xml-rpc api does (tested).

Some example scripts:

http://www.spacewalkproject.org/documentation/api/2.1/scripts.html

And in your particular case, the script you'd want (in python):

...
#!/usr/bin/python
import xmlrpclib

SATELLITE_URL = "http://your.spacewalk.url.com/rpc/api"
SATELLITE_LOGIN = "youruser"
SATELLITE_PASSWORD = "yourpassword"

system_id = 0 # change this to the system id you want to schedule the run for
user = "root"     # change this to the user to run the remote command as
groupt = "root"  # change this to the group to run the remote command as
timeout = 60 # in seconds
script = """
#!/bin/bash

echo "whatever" > /tmp/wherever
"""

client = xmlrpclib.Server(SATELLITE_URL, verbose=0)

key = client.auth.login(SATELLITE_LOGIN, SATELLITE_PASSWORD)
client.system.schedule_script_run(key,
    system_id, \
    user, \
    group, \
    timeout, \
    script, \
    xmlrpclib.DateTime())
client.auth.logout(key)
...
