Greetings .
Please a little help.
How do I uninstall an app from the terminal and delete all references to the app.
dpkg -???

apt-get remove
http://manpages.ubuntu.com/manpages/...apt-get.8.html

and you can install instead of using application manager with : apt-get install (package name)
you seem to be new to x-terminal read learn more before you command so you dont fall into problems

./sifo

apt-get remove / apt-get purge
Eliminate the application, but are folders created in (eg) .config
There is a command to delete the application and folders that are created in home/user/.config or home/user ?

those are small files (in KB) if you removed the application with apt-get remove then you can delete that files if you want with :

rm -r /home/user/(folder name) this one for folders and its content

rm (file path) this one for files

and remember you need to be root before doing that

./sifo

SIFO Thanks and you too ZIMON.
