hope this fix your issue It should work as you said.
One possible reason you don't see the \r is that the editor you're using detect the fileformat (line ending) and hide the CR.

To fix this issue You will have to use mount because the kernel controls mounting partitions within the operating system for security reasons. You can use mount without superuser/administrator privileges. Try something like this:
Make sure that the directory (/mnt/usb1/) you are mounting to already exists, and then
code :
mount /dev/sdb1 /mnt/usb1 -o noauto,users,rw,umask=0

hope this fix your issue There are various topics available on this very topic, "How to write output to the text file". But my issue is different because the output to the command in question is continous. , So you are trying to create a pipe. Try this:
code :
import subprocess

p = subprocess.Popen(["cgps", "-s"], stdout=subprocess.PIPE)

with open("aaa.txt", "w") as f:
    while True:
        line = p.stdout.readline()
        if not line:
            break
        if some_condition(): # <-- check whether you have enough output
            p.terminate()
            break
        f.writeline(line)

p.wait()

like below fixes the issue The problem was I was running a cron job that copied the data to another file which was accessing the file being written to in the python program.
The first write after this was not saving to the file as it was being accessed by another program.

Does that help If you want to run your Python script as an executable, put the right shebang at the top of your .py file. For example, hello.py might be defined as:
code :
#!/usr/bin/env python

print('hello, world!')
$ chmod u+x hello.py
$ ln -s hello.py hello

Any of those help I noticed I have two alternatives to writing to a file in Linux within a python script. I can either create a Popen object and write to a file using shell redirection (e.g. ">" or ">>") - or I can use File Objects (e.g. open(), write(), close()). , Generally speaking, I would write something like:
