Laptop A has python file "file1.py". Computer B has python file "file2.py". I want to remotely enter into Computer B and run the python script file2.py. I am using SCREEN, and below is my code.
import os
import time
os.system('screen -S Test -d -m /dev/ttyUSB0 57600')
time.sleep(1)
os.system('screen -S Test -X stuff "file2.py"')
time.sleep(1)
os.system('screen -S Test -d -r')
time.sleep(0.25)
print "done"
How did you try to run your 'remote' script?
You can try ssh session:
ssh user@computer_b 'python file2.py'
Of course, you should provide a full path to your file2.py script and maybe (I'm not 100% sure) a full path to a Python executable on your remote Computer B. Another option is to make your file2.py executable, by adding a Python "shebang line" as the first line of your file2.py script and setting executable bit via chmod +x file2.py:
Should I put #! (shebang) in Python scripts, and what form should it take?
ssh may need extra options depending on what file2.py tries to do. For example, a -t option is often needed when using sudo on the remote
file2.py remotely, as I see from your code. You try to launch file2.py script locally from your Laptop A via screen, but screen doesn't run scripts or programs remotely by itself. You should implement usage of ssh to run scrips remotely.
