Thank you everyone for the help. I have two solutions, but I would
love one that uses the subprocess.Popen() - I have no experience with
this module.class - if someone with more experience would feel
inclined to provide an example, I would be very much appreciative.
SOLUTION 1 (my brute force method)
create a csh file which does what I want,
##### filename: hack.csh
#!/bin/csh
set RUN_DIR = $1
set EXEC_DIR = $2
cd ${RUN_DIR}
${EXEC_DIR}/my.exe
#####
then I call this in my python code from some arbitrary directory
##### python script...
os.system('./hack.csh /scratch exec_dir')
#####
SOLUTION 2 (courtesy of my computer-superhero friend - again simple)
in my python script...
#####
import os
curdir = os.path.abspath('.') # in case I need to get back to
where I am - in my case no
os.chdir('RUN_DIR') # in my case RUN_DIR = /scratch
if I wanted to get back to my old directory - then add
os.chdir(curdir)
#####
so both of these methods are sort of brute force - being completely
unfamiliar with the subprocess module, again is someone would like to
provide an example, or at least more hints than
'you should use subprocess.Popen()'
I thank you in advance.
Cheers,
Andre
