I don't know anything about tcl but I use perl and python to interact with
houdini. A few months ago I asked about calling python from houdini in a
custom function and got some helpful responses. You might want to search the
archives in this respect.

In any case.......
In the textport if you type exhelp system. You'll see:
# / --------------------------------------
string system (string)
Returns the output of a unix command.
# / --------------------------------------

So I created a sample python script in my home directory called test.py
inside i just have:
# / --------------------------------------
print "Hello from Python"
# / --------------------------------------

Now inside houdini, I typed the following in the textport:
# / --------------------------------------
set myCmd = `system("python $HOME/test.py")`
echo $myCmd
# / --------------------------------------

The result is:
Hello from Python

Hope this helps,
