Running .sh file from Python script?

Question

I am having trouble running a .sh script in Oracle Linux 6.8 using a python script I have developed. I've developed these scripts in Windows OS and they run without a problem, now I am trying to modify these scripts to run them on Linux but I am having problems since I am not familiar with Linux OS.

I run a .bat file in Windows using the Popen command in python, for example: p = Popen("StartScript.bat", cwd=r"My path")

Where StartScript.bat is the .bat file, and My Path is the path where the .bat file is located. This works very good in Windows OS, but how do I do the same for Linux OS, if I want to run a StartScript.sh file.

Gaurav Pathak, according to the links you have provided, there is no need to enter a path (where the .sh file is located) to execute the .sh file when using Popen? Is this right?

@viganqerimi You need to provide the path of the shell script. If Popen("StartScript.bat", cwd=r"My path") is not working for you. May I know the error that you are gettting?

FileNotFoundError: [Errno 2] No such file or directory: 'start_stageconv.sh'

What I need is the equivalent of my popen command that I have used in Windows OS, but for LINUX OS. So I can execute my .sh script using python. Is this going to work: p = Popen(['./start_stageconv.sh'], stdout=PIPE, stderr=PIPE)

@viganqerimi Use p = Popen(["sh", "./start_stageconv.sh"], stdout=PIPE, stderr=PIPE) You can also provide the path of the shell script instead of ./start_stageconv.sh if you don't want to put your python script in the same directory also I suggest to check the presence of file using os.path.exists() before passing it to subprocess.Popen()

use this lines:

import os
os.popen('sh command')

for example

import os
os.popen('sh /home/oracle/scripts/start.sh')

enjoy
