How to run linux terminal command in python in new terminal

Question

I read multiple answers regarding how to run the linux shell command using subprocess module in python. In my case, i need to run linux shell commands inside my python code in such a way that these commands should get executed in new terminal.

subprocess.call(["df","-h"]

I'm running say xyz.py in base terminal, when i execute above command, it overwrites on the output of xyz.py in the same terminal. I want this command to be executed in different terminal, or i want to store output of this command in a text file.

subprocess.call(["df","-h",">","somefile.txt"])

Above command is not working.

Edit-1: If i save the output in a text file, i also have to display it through python.

Thanks!

import subprocess
fp = open("somefile.txt", "w")
subprocess.run(["df", "-h"], stdout=fp)
fp.close

Use a file handle.

If you want to print the output while saving it:

import subprocess
cp = subprocess.run(["df", "-h"], stdout=subprocess.PIPE)
print(cp.stdout)
fp = open("somefile.txt", "w")
print(cp.stdout, file=fp)
fp.close()

Thanks. It's working. Problem is, if i save it in a text file, i also have to display it using python. – spectre Apr 13 '18 at 09:08
@spectre You can use `stdout=subprocess.PIPE` to get the stdout, print it and then save it to the file. – iBug Apr 13 '18 at 12:03
Even before running the code, it shows error with "print(cp.out, file=fp)" line. – spectre Apr 13 '18 at 14:36
@spectre It's a typo. Fixed now. – iBug Apr 13 '18 at 16:18
Still it shows same error. Can you please check once and edit it. Thanks. – spectre Apr 20 '18 at 09:18
@spectre Is it Python 2 or Python 3? I'm not familiar with Python 2. – iBug Apr 20 '18 at 15:08
It's not working in python3. It prints random data from the file. – spectre Apr 20 '18 at 18:11
Is it working in your compiler? Can you please check the syntax once? – spectre May 06 '18 at 18:37
@spectre What Python version are you using? – iBug May 06 '18 at 23:16
I'm using inbuilt Python 3 version in linux. – spectre May 07 '18 at 05:43
@spectre That's not enough. Which Python 3 version? 3.5 or 3.6 (or else)? Different "minor" versions can differ *a lot* in behavior in certain circumstances. – iBug May 07 '18 at 08:00
It's python 3.5.2 – spectre May 07 '18 at 09:05

have you tried the os.system?

os.system("gnome-terminal -e 'your command'")

Thanks. Problem with this is, new terminal is getting opened. But it's unable to execute the command inside new terminal – spectre Apr 13 '18 at 08:51
And what about creating a child with os.fork? – Marcos Martinez Galindo Apr 13 '18 at 08:52
os.system(" gnome-terminal -e '['df','-h']' ") This is what i did. What corrections do you suggest? – spectre Apr 13 '18 at 08:58
I think this works fine, but if you want you can try fork to create a child (new process). See this: https://stackoverflow.com/questions/33560802/pythonhow-os-fork-works – Marcos Martinez Galindo Apr 13 '18 at 09:10
The correct syntax is `os.system("gnome-terminal -e 'df -h'")` or better `subprocess.run(["gnome-terminal", "-e", "df -h"])` – tripleee Jul 09 '22 at 19:33

file = open("somefile.txt", "w")
subprocess.run(["df","-h"], stdout = file)
os.system("gnome-terminal -e 'gedit somefile.txt' ")

Above code is working. If there are any simple/efficient way to do the same it'll be helpful.
