Hi,
I usually use csh for my simulation control scripts, but these scripts
are becoming more complex, so I plan to use python for the next
project.
To this end, I am looking at subprocess.Popen() to actually call the
simulations, and have a very basic question which is demonstrated
below.

Hello World!
This is my first post on the list and I'm hoping it is the right forum and
not OT, I've searched
a bit on this, but, none-the-wiser!
My question is on the Popen method, here is my snippet:
p1 = Popen(["cat", "georgi_ddr7_allmag_kcor_in_test.dat"], stdout=PIPE )
> p2 = Popen(["fit_coe
First, I think you should use subprocess.Popen (it's recommended by
PEP-324) instead of os.popen. For example:
p = subprocess.Popen(["top"], stdout = PIPE)
p.stdout.readlines()
And to write to stdin (in your case "q") you can use p.stdin.write("q"), or
terminate the process with p.terminate(
os.popen('top -n1').readlines()
Hm, interesting. On Mac OS X's (and BSD's?) top, -n instead specifies
the number of processes to list at a time (i.e. list only the top N
processes), which is entirely different.
[reaching over to my Mac] Looks like "top" there supports a -l
parameter which do

It calls the command line "top" and will print out some texts.
But first I have to press the keyboard "q" to quit the subprocess "top", then

Hi all,
I write a small script
texts = os.popen('top').readlines()
print texts
It calls the command line "top" and will print out some texts.
But first I have to press the keyboard "q" to quit the subprocess "top", then
the texts will be printed, otherwise it just stands by with blank.

hello everyone :-),
I am a newbie to python. I am trying to run a
bash script from within a python program. I would greatly appreciate
any pointers/comments about how to get around the problem I am facing.
I want to run bash script: code.sh from within a python program.

pexpect is the solution. Seems to wrap quite a bit of dirty pseudo-tty

Say I have a Windows executable, foo.exe.
foo.exe is a command line tool that can take a number of different
arguments and perform corresponding actions.
