subprocess.call(["echo",instance.Username]) # => works .
subprocess.call(["username=",instance.Username]) # => error
subprocess.Call(["username","=",instance.Username]) # => error
subprocess.call(["username=",instance.Username],shell=True)
# => no Error but when i do echo $username there is nothing inside..
would you help me, I just want to put the value of instance.Username in a bash variable.
Thank you.
You'll want to pass it as an environment variable to subprocess.call() like so:
env = {
'username': instance.Username,
}
subprocess.call(['./your_script.sh'], env=env)
This will make the environment variable $username available to your bash script.
Remember to enclose the bash command in a list, run the script with ./, and start the script with the correct shebang, (all things I forgot to do while writing this).
subprocess.check_output for that.
subprocess.call(['echo', '$username'], env={'username':'AdamBarnes'}).subprocess.call('echo $username', env={'username':'AdamBarnes'}, shell=True). Note that you won't need shell=True when calling your script, and you shouldn't use shell=True if you're ever passing user-supplied data to subprocess.call().
