Python script execute commands in terminal

Question

I read this somewhere a while ago, but did not seem to find it. I try to find a command that will execute commands in the terminal and then print the result.

For example: a script would be:

command 'ls -l' 

It gives the result of executing this command in the terminal

Answer 1

There are several ways to do this:

A simple way is to use the os module:

 import os os.system("ls -l") 

More complex things can be achieved using the subprocess module: for example:

 import subprocess test = subprocess.Popen(["ping","-W","2","-c", "1", "192.168.1.70"], stdout=subprocess.PIPE) output = test.communicate()[0] 

Answer 2

I prefer to use the subprocess module:

 from subprocess import call call(["ls", "-l"]) 

The reason is that if you want to pass some variable to a script, this gives a very simple way, for example, to take the next part of the code

 abc = ac call(["vim", abc]) 

Answer 3

• Custom standard input for python subprocess

In fact, any question about the subprocess will be a good read

• stack overflow

Answer 4

You should also look at .getstatusoutput commands

It returns a tuple of length 2. The first is the integer return (0 - when the commands are successful); the second is the entire output, as shown in the terminal.

For ls

  import commands s=commands.getstatusoutput('ls') print s >> (0, 'file_1\nfile_2\nfile_3') s[1].split("\n") >> ['file_1', 'file_2', 'file_3'] 

Answer 5

os.popen () is pretty simple to use, but it's deprecated since Python 2.6. Instead, you should use the subprocess module.

Answer 6

 import os os.system("echo 'hello world'") 

That should work. I do not know how to print the output to the Python shell.

Answer 7

You can import the os module and use it as follows:

 import os os.system('#DesiredAction')

In the desktop GUI (some of you may not use it), you can scroll through the desktop shortcut and have a command in it to open the cancellation file. If you copy and paste it into your python interpreter, it should work. (I'm not sure if this will work, but why not give it a try!) Sorry for all the spelling mistakes ... I'm only 11.
