If you have questions or suggestions, please feel free to drop a comment below. In a related quick tip, you can learn to write list to file in Python. I hope this quick tip helped you to execute shell command in Python programs. rw-r-r- 1 abhishek abhishek 212 Jan 17 16:54 prog.py When you run the program, you’ll see the stdout and stderr (which is none in this case). You can learn more about the subprocess module here. It outputs to the Popen object which has a communicate() method that can be used to get the standard output and error as a tuple.
#Python open terminal and run command how to
Now that you know how to run shell command with subprocess, the question arises about storing the output of the shell command.įor this, you’ll have to use the Popen function. When you run the program, you’ll see the content of the current directory in the list format. If you want to provide the options and the arguments along with the shell command, you’ll have to provide them in a list. You’ll see the content of the current working directory when you run the program: python prog.pyĪgatha.txt count1.txt file1.txt prog.py target The call method will execute the shell command. If you want to run a shell command without any options and arguments, you can call subprocess like this: import subprocess Execute shell command in Python with subprocess moduleĪ slightly better way of running shell commands in Python is using the subprocess module.
Now let’s see another way of running Linux command in Python. If you run the above program, it will print the content of the variable m圜md and it will be the same as the output of the ls command we saw earlier. You can also store the output of the shell command in a variable in this way: import os If you want to use the output of the shell command, you can store it in a file directly from the shell command: import os That’s the content of the directory where prog.py is stored. rw-r-r- 1 abhishek abhishek 356 Dec 11 21:35 sherlock.txtĭrwxr-xr-x 3 abhishek abhishek 4096 Jan 4 20:10 target rw-r-r- 1 abhishek abhishek 44 Jan 17 15:58 prog.py rw-r-r- 1 abhishek abhishek 356 Dec 17 09:59 file2.txt w-r-r- 1 abhishek abhishek 356 Jan 17 12:10 file1.txt The next line does exactly that, runs the echo command in our shell through Python. rw-r-r- 1 abhishek abhishek 14 Jan 10 16:12 count2.txt The first thing we do in our Python file is import the os module, which contains the system function that can execute shell commands. rw-r-r- 1 abhishek abhishek 14 Jan 10 16:12 count1.txt rw-r-r- 1 abhishek abhishek 0 Jan 17 12:11 count r-r-r- 1 abhishek abhishek 456 Dec 11 21:29 agatha.txt python prog.pyĭrwxr-xr-x 3 abhishek abhishek 4096 Jan 17 15:58. Now, if I run this program, here’s what I see in the output. Let me create a simple python program that executes a shell command with the os module. Execute Shell command in Python with os module In this tutorial, I’ll show you a couple of ways you can run shell commands and get its output in your Python program. Since the sysadmin tasks involve Linux commands all the time, running Linux commands from the Python script is a great help. More and more sysadmins are using Python scripts to automate their work. Python is an excellent scripting language.
