Question

By default, vundle install vim plugins to ~/.vim/bundle/ on linux machine.

How can I make it install plugins to:

~/here/please/vundle/install/all/plugins/

Answer 1

It should be as simple as passing the target directory to the rc() function when you set up vundle. The implementation of that function explains it well enough if you know a bit of vimscript:

func! vundle#rc(...) abort
  let g:bundle_dir = len(a:000) > 0 ? expand(a:1, 1) : expand('$HOME/.vim/bundle', 1)
  let g:vundle_log = []
  call vundle#config#init()
endf

Instead of just calling

call vundle#rc()

in your vimrc, use

 call vundle#rc("~/here/please/vundle/install/all/plugins")
