I have a script somewhat like that which I use:

-------------- distrib ------------------------
#!/bin/sh

if [ $# = 2 ] ; then
  where=$2
else
  where=$3
fi

hosts=`cat $1`

for i in $hosts
do
  echo "$i--------------------------- "
  scp $2 ${i}:$where
done
----------------------------------------------

The syntax is:

distrib machinelist file

OR

distrib machinelist file placetoputit

machinelist is a file containing a list of machines to copy to, one
per line.

The above could be modified to take a list of files to copy, and a
directory to copy them to.

For that matter, if you're using different directories on the
different machines, you could put that directory with the machine
names in the file with the list of machines, like so:

--------- file --------------
host1:/home/emma/
host2:/home/hogbin/
host3:/home/ehogbin/
-----------------------------

You'd have to change the scp line in the above to take out the ":",
but that's all you'd have to do.

Making it take a list of files instead of just one shouldn't be too
terribly hard either -- I think you'd assign the $1 to some variable,
then use "shift" to get rid of it, then use $* to get the whole list
of files.  Sorry if that sounds vague... I'm far from being a
scripting expert.  :-)
