Problem with bash shell needed for my python project

[Gribouillis]

This seems to give better results

#!/bin/bash
FILTER1="@id @lat @lon name value"

/home/eric/bin/echoargs --csv="$FILTER1"

Output:
~/P/S/2021-01 paillasse/pf/script.sh
['/home/eric/bin/echoargs', '--csv=@id @lat @lon name value']

I used here my awesome 'echoargs' program to check command line arguments:

#!/usr/bin/env python3
# echoargs script
import sys

if __name__ == '__main__':
    print(sys.argv)
