Should I remove vim before installing vim-gnome? It seems redundant to leave vim there, but I'm afraid to remove it. (I'm very new to Ubuntu.)
You can have as many flavours of
vim installed in you system like
vim-basic(provided by default),
You can then choose which binary to use by giving preference of one over another using
update-alternatives decides which binary to execute depending on your preference when
vim is used.
vim binary (
/usr/bin/vim) is a symbolic link to
/etc/alternatives/vim, which in turn is a symbolic link to your preferred one (e.g.
/usr/bin/vim.basic). You can read this to get more idea on this.
So you can install as many flavours of
vim you want, you just need to choose the one you want to execute by using the preference.
