mrXmr Composer is usually a single executable file, if you know where it is you can delete it with root privilege.
If you don't know where it is but access it via composer
, you can run which composer
to find its location (for example, on my system it returns /usr/local/bin/composer
).
If you uninstalled Composer then you can also delete the entire ~/.local/composer
or ~/.composer
folder that holds any Composer configuration or cache. There will be one hidden Composer folder for every shell user that ever ran Composer.
