Passing Commands To Hscript On Start Up

[doc]

Here's my dilemma, I want to start hscript from the textport of an open houdini session.

after opening hscript I want to execute the openport command

something like:

unix "hscript myfile.hip"

unix "openport 77000"

The only problem with this is the unix command will spawn two separate processes.

I tried the following:

unix "hscript myfile.hip; openport 77000"

but his doesn't work either, rather than executing openport in hscript it's trying to execute it in

the shell.

I also tried:

unix "hscript myfile.hip\; openport 77000"

and

unix "hscript myfile.hip < openport 77000"

without success, anybody have any ideas?

many thanks

Luca

tried this as well:

echo "openport 72000" | hscript &

but it didn't work

You might have to create a tmp file with your commands first and then run "unix hscript myfile.hip myscript.cmd"

As an alternative to Edward's suggestion, you could wrap the hscript launching in a simple Python script that you call instead (ie 'unix "launchHscriptAndOpenPort myFile.hip 77000"') where launchHscriptAndOpenPort would look something like (I haven't tested this, so there may be typos):

#!/bin/python
import os
import sys
file  = sys.argv[ 1 ]
port  = sys.argv[ 2 ]
houdini = os.popen( "hscript "+file, "w" )
houdini.write( "openport "+port )
os.wait()
houdini.close()

I'm also not sure if this only works on Linux or not (I seem to remember os.wait() is not a Windows-happy function). Wow, ok, so maybe this isn't the most versatile suggestion after all

thanks Rob,

I actually ended up using popen2 to open hscript with the optional .cmd as Ed suggested.

And then I used openport to send commands to the hscript session.

Your method looks better though. I should just be able to send commands straight to

hscript and bypass the whole openport buisness completely.

Thanks!
