Ubuntu How to run Python script on Login?

warnetgm · 08-11-2005, 08:48 AM

Hi,

I'm using Ubuntu Linux, I have python script, how to start it on every login and stay running on background until log off ?

Thank You

For an individual user, just add it to .bash_login in your users home directory.

I open my home user folder, but there is no file at all except just a Desktop folder.

Anyway I'm mostly running script like this :

#python
>>import client
>>client.init()

how to do that? anyway can I just run the binary one without the script source ?

Thank You

Is there a way easily add the binary code of my python program such in windows Programs - StartUp ?

Thank You

First create your python script..

Then in your .bash_login (create it if it doesn't exist) just call for the script by specifying the path and the python script name... for e.g:

/path/to/your/python/script/script_name.py

trickykid,

In the interests of pushing the envelope, what about before login? is possible to run any script at all, on boot? Say, a mp3 soundbite, before login?

rc.local or any of your other startup scripts you can customize..

Hi trickykid,

I'm newbie in linux, doesn't quite understand many things linux, I'm just starting migrating from windows to linux.

I'm trying to create a .bash_login file and put :

/home/user/client.py

but that doesn't working, trying to put :

python
import client
client.init()

stil doesn't working, remove the "python" line also not working (each trying logoff and login).

If I didn't misunderstand, by using .bash_login do you mean that I should use Bash Script ?
After I'm reading the web, there is special start up bash file for init the system but the name is .bash_profile not .bash_login
I'm even tried to put /home/user/client.py in .bash_profile but nothing happen.

Anyway could you please help me out by step by step on how to do it, because I'm really confuse.

Thank You

In .bash_profile , if I put python maybe it wil run it, but how can I input :

>>import client
>>client.init()

or is it really just put the path of my client.py it will working ?
because it doesn't

or maybe the path is wrong ?
I tried :

/home/user/client.py
/user/client.py

both doesn't work

Please Help Thank You

The file needs to be like this:

PHP Code:


			
#!/bin/bash

python /home/user/client.py

The first line identifies it as a bash script, and then it calls python and tells it to read the python script. It probably also needs to be marked executable:

PHP Code:


			
~> chmod +x .bash_login

Sorry no one was able to help you with this before.

You could also put the script invocation line in the python script like:

Code:

#! /usr/bin/python

import client
client.init()

Then set the script as executable:

Code:

chmod +x /home/user/client.py

Then you can reference it from your .bash_login, .bash_profile or .bashrc

Code:

/home/user/client.py

I don't normally use .bash_login but .bash_profile is only run for at login and .bashrc is run for every shell.

If you need your script run for all users, you can put your script in /etc/bash.bashrc, but I would read some of the comments in this file to see if it is right for your purpose.

If you are looking to have this script run at system startup. I would put the script in /usr/local/bin and then I would link to it in one of the /etc/rc#.d directories, probably /etc/rc3.d.

Code:

 sudo ln -s /usr/local/bin/client.py /etc/rc3.d/K90client

Thanks

To run a simple python script in ubuntu :

# python
>>> vi test_python.py

This is the python script :

#!/usr/bin/env python -----Note : This line is mandatory-------------

""" CGI test 1 - Check server setup."""
# Check the first python script

print "Content-type: text/html"
print
print "<h1> Hello Harsh </h1>"
print "<p> This is python_test.py"
-------------END--------------------

To run a python script :

1. # python test_python.py
or
2. # chmod +x test_python.py
# ./test_python.py

Umm, okay, but how does this relate to running one at login at the command line like the original question asked?
