I am not able to find trash anywhere. Can you please tell me a command or anything like that to empty the trash using terminal ?
You can use the rm command:
rm -rf ~/.local/share/Trash/*
The rm command removes (deletes) files or directories.
-f, --force Ignore nonexistant files, and never prompt before removing.
-r, -R, --recursive Remove directories and their contents recursively.
The trash folder is found at: $HOME/.local/share/Trash
Be careful how you use the rm command - the files aren't sent to a trash can where you can undelete them, so it's not easy to undo.
