I am using python2.7.10 on MacOs Sierra and have created a rsync over ssh connection with my raspberrypi. The Idea is to synchronize my local folder with my remote folder on the raspberrypi.

My function syncroFolder() is working fine, but how can I show the real time status on my tkinter window ? is there any easy solution ? I can't understand the question posted: "Redirect command line results to a tkinter GUI"

def syncroFolder():os.system("rsync -avz -e \"ssh -p port\" /source/path /folder/to/rcync ")

Thank you for your help

2017-09-05: I managed to write the result in a file with the "| tee " my command looks like this now

os.system("rsync -avzr -P --info=progress2 -e \"ssh -p %s\" %s %s | tee %s & "  %(port,dossier,destination,exampleOutputTxtAdd))

I have created a textbox in TKinter that display the last line of the file

status, lastLineInFile = commands.getstatusoutput("tail -n 1 "+ exampleOutputTxtAdd)
T.insert(END,'Transfering: \n'+lastLineInFile)

The output file looks like this:

sending incremental file list
folder/0   0%    0.00kB/s    0:00:00 (xfr#0, to-chk=397/410)
folder/Bigfile.avi32,768   0%    0.00kB/s    0:00:00  2,555,904   0%    2.39MB/s    0:07:18  3,112,960   0%    1.41MB/s    0:12:23  3,637,248   0%    1.11MB/s    0:15:44

but the textbox shows all those lines

  Transfering3,776   0%    0.00kB/s    0:00:00 16,567,040   1%   13.69MB/s    0:01:15  

and keep adding lines, even if I read the -n = 1 line of the output file.

I have been trying to use the --out-format=\"%t %o %f %b\", but then I have the status only after transfer (in case of a big file)... I tried many options and none worked for me... I don't understand why it doesn't display only the last line of the output file. Do you have any suggestions ?

Here is an example using python3 (because that's what I have). The essence is as in the references example to use a thread to read the pipe line by line into a queue and then use an after event to read the queue. Enhancements would be to read all items from the queue each time and stop the after event sequence once the subprocess has halted. Test using python3 tkinter_rsync.py rsync://servername/sharename or something like that.

import sys
import tkinter as tk
import tkinter.ttk as ttk
from subprocess import Popen, PIPE
from threading import Thread
from queue import Queue, Emptydef read_pipe(widget, queue):interval = 1try:line = queue.get_nowait()except Empty:interval = 5passelse:widget.insert('end', line)widget.after(interval, lambda: read_pipe(widget, queue))def queue_line(pipe, queue):for line in iter(pipe.readline, b''):queue.put(line)pipe.close()def main(argv):root = tk.Tk()text = tk.Text(root)vs = ttk.Scrollbar(root, orient='vertical', command=text.yview)text.configure(yscrollcommand=vs.set)text.grid(row=0, column=0, sticky='news')vs.grid(row=0, column=1, sticky='ns')root.grid_rowconfigure(0, weight=1)root.grid_columnconfigure(0, weight=1)process = Popen(['rsync', '--list-only', argv[1]], stdout=PIPE)queue = Queue()tid = Thread(target=queue_line, args=(process.stdout, queue))tid.daemon = Truetid.start()root.after(0, lambda: read_pipe(text, queue))root.mainloop()if __name__ == '__main__':main(sys.argv)
