Redirection problem

[Mahmoud-Ibrahim-750]

Problem: Here is the error that pops up when I run the app:

***@***:~$ vnstat-client
20:40:26.790 › [PRODUCTION] vnStat Client is Running.
20:40:27.350 › Getting data...
20:40:27.351 › APPIMAGE env is not defined, current application is not an AppImage
20:40:27.457 › Error: Command failed:                                                                       
                    if grep -q "$(systemctl is-active vnstat)" <<< "active" ;
                        then echo "true"                                        
                    else echo "false"
                fi

And the app is unable to read data from the database however vnstat works perfectly and shows data in the terminal.

Possible solution: After some research, it looks like that the script is using Dash instead of Bash (because I use Ubuntu) so it may solve the problem if Bash is used instead of using the default shell in the script. This may not be the best solution and you should consider other possible solutions if found.

For now, I think you can try this command to run vnstat-client

$ bash -c "vnstat-client"

After college exams, I will try to work on your issue but I want more information about your system. I think the neofetch output will be enough.

When I tried your suggestion, I got typically the same result I provided earlier. Anyway here's the neofetch you asked for, If you need more info, just tell me.
