[SOLVED] execute bash script from pySide script

sharky · 12-22-2013, 12:36 PM

I wrote a tcltk script that 'catches' stdout from a bash script and saves it to a variable. The proc is executed in the interface with a command button.

Trying to do the same thing in pySide and haven't a clue. I'm a pySide noob and the whole signal/slots things is a foreign language to me at this point.

I'm sure this is documented somewhere and I'm reading stuff but haven't found anything that addresses this particular situation.

If someone has an example, explanation, or tutorial on how to do this it would be appreciated.

Thanks in advance.

Made some progress.

First defined a function that calls a bash script. The bash script is stupid simple doing nothing but "cat ~/.bashrc'.

Was able to connect the function to a button. It works. Clicking the button caused by ~/.bashrc file to be returned to the terminal.

This is the python function;

Code:

import sys
import subprocess

def get_quota():
	process = subprocess.call(['/home/me/scripts/pySide/dummy.sh'])

I was expecting that nothing would get returned unless I specifically printed "process".

Is there a way to prevent stdout from returning to the terminal?

Thanks again.

Baby steps;

Can now suppress/control the output. The function now looks like this.

Code:

import sys
import subprocess

def get_quota():
	process = subprocess.Popen(['/home/me/scripts/pySide/dummy.sh'], stdout=subprocess.PIPE)
	quotaout = process.communicate()[0]
        print quotaout

The problem now is getting quotaout into the textedit widget.

Moved the function definition into the main window class and called it with 'self' and it works.
