run shell command from python code example

Example 1: executing shell commands from python script

import subprocess
subprocess.run(["bash", "testShell.sh"])
#we don't have to give full path to the shell script. It always execute from the current directory

#As a rule of thumb, you need to separate the arguments based on space, 
#for example ls -alh would be ["ls", "-alh"], while ls -a -l -h, 
#would be ["ls", "-a", -"l", "-h"]. As another example, 
#echo hello world would be ["echo", "hello", "world"], 
#whereas echo "hello world" or echo hello\ world would 
#be ["echo", "hello world"].

#Another example.
list_files = subprocess.run(["ls", "-l"])
print("The exit code was: %d" % list_files.returncode)

Example 2: python run a system command

import os
cmd = "git --version"
returned_value = os.system(cmd)  # returns the exit code in unix

Example 3: call shell script from python

import subprocess
subprocess.call(["./shell.sh"])

# Make sure that "shell.sh" has "+x" permissions

Example 4: python run shell command

# First, install python or python3...
sudo apt-get install python 
#or 
sudo apt-get install python3

# Then, run your python file...
python /path-to-file/pyfile.py #or
python3 /path-to-file/pyfile.py
#Example
python /home/person/randomfile.py #or
python3 /home/person/randomfile.py

# Hope this helped :)
