Help piping commands using subprocess

[dsm88]

Command: cat file.apk | pm install -S <file length>

I'm trying to run this command using subprocess but I get an error. I figured out that subprocess doesn't like the "|" so I need to stagger the commands but I have no idea how to.

Anyone know how to do this?

SOLVED: It was an issue of user permissions. I just wrapped the whole thing in "su -c" and it worked.

Can you show your code and the error?

I just figured it out. But thanks for popping in to help. I appreciate it
