如何通过 Python 程序以该用户身份切换用户并执行多个终端命令

Question

I am working on an automation program that I want able to run this string of Linux commands in succession, then close the subprocess: "su my_user", "cd ~/asdf/qwer/", and "sudo bash zxcv_zcv.sh".

I am on python 2.7 and I have tried using these commands so far:

subprocess.call("su my_user; cd ~/asdf/qwer/; sudo bash zxcv_zcv.sh",shell=True)
subprocess.Popen("su my_user; cd ~/asdf/qwer/; sudo bash zxcv_zcv.sh",shell=True)
os.system("su my_user; cd ~/asdf/qwer/; sudo bash zxcv_zcv.sh")

so far, the only thing that happens is the program creates a new terminal that I can interact with under my_user. I do not want to even see the terminal and this has not happened for any other Linux command I have run through subprocess or os. Does anyone know what is happening and how I can fix this?

Answer 1

Okay, I just found the answer to this question for anyone wondering. For the string of commands I used, just add a -c between "su" and "my_user" and it will run fine.

subprocess.call("su -c my_user; cd ~/asdf/qwer/; sudo bash zxcv_zcv.sh", shell=True)
