Other answers do mention that argparse is the way to go for new Python, but do not give usage examples. For completeness, here is a short summary of how to use argparse:

1) Initialize

import argparse

# Instantiate the parser

parser = argparse.ArgumentParser(description='Optional app description')

Sample config for 2 million web socket connection

    sysctl -w fs.file-max=12000500
    sysctl -w fs.nr_open=20000500
    # Set the maximum number of open file descriptors
    ulimit -n 20000000

    # Set the memory size for TCP with minimum, default and maximum thresholds 
 sysctl -w net.ipv4.tcp_mem='10000000 10000000 10000000'

Backing up FreeOTP

Using adb, create a backup of the app using the following command:

adb backup -f freeotp-backup.ab -apk org.fedorahosted.freeotp
