Python os.exec(): Termination on running 'notify-send'
Question: I'm writing a small Python script under Linux that pops up a number of
`libnotify` pop-ups, currently by using the following syntax:

    
    
    import os
    os.execv('/usr/bin/notify-send', ['App Title', 'Message'])
    

Unfortunately, and for some strange reason, it kills the interpreter right out
to the command-prompt.  
It doesn't do this with any other command the script executes, just `notify-
send`.

There's no error given, no known exception thrown, no indication of anything
wrong, it just dies out to the command prompt.

Does anyone have suggestions or alternatives that equally easy to do?


Answer: You should use `subprocess.call` which starts the program named by its
arguments in a new process and waits for the child process to exit rather than
`os.execv` which replaces what is running in the current process with the
program specified by its arguments.

The usage is `subprocess.call(['/usr/bin/notify-send', 'App Title',
'Message'])`
