Hi all!!
I'm writing a script where i call a external program which receive some
arguments.
One of this arguments is stored in a variable, that is passed as
argument as well:
import os
...
f = open(file1, 'r')
s = 'command $f -i file2 -w 1.4 -o file3.out'
os.system(s)
...
When i run the script i get the next message...
'-i: No such file or directory'
... with a obvious error in the exit of the program. If i remove the
option -i i get the same error with every option, even with those who
don't get any file as argument. (file2 exist).
BUT, when i run the external program in a python shell, it works...
What's wrong?
The name 'f' in the Python script exists only in Python and is unrelated
to the '$f' that the shell sees.
