Question: Need help to understand the output of `ls -l` command. I created one file `testa` in my home directory. When I run the `ls -l` command it shows up with two similar names. What does the symbol (~) mean with the file "testa". Below is the sample output:

```
testa
testa~

```

Answer: 
Try rclone

```
sudo apt install rclone

```

to configure:

```
rclone config

```
