executing an external app

[Joseph Krauze]

Hi all,

I have a simple question which I cannot solve (relatively new to Python).
I want to write a script that executes an application on the go. I looked
into the exec*e() calls but the problem there is that they do not return.
I also looked into execfile() but here the PATH is not taken into account
and I couldn't figure out to pass the file that's executed arguments.

So, is there a simple way to execute an external app?
i.e. execvpe('cat', 'myFile') - this will not return

Thanks,
Joseph

Try one or more of these:

os.system, os.spawn*, popen2.*, os.fork + os.exec* (where os.fork is
supported, at least), popen5 (third-party module, posix/unix only),
win32??? (not sure of name, included in win32all, for Windows only)

Look at os.spawn* or os.popen*

Look at os.spawn* or os.popen*

And os.system(). And commands.getoutput().

And os.system(). And commands.getoutput().

[jepler@parrot jepler]$ python -c 'import this' | grep "only one"
There should be one-- and preferably only one --obvious way to do it.

*sigh*

You could try process.py. Windows and Unix.
