vim调用系统剪切板复制粘贴

" On OSX
vmap <C-c> y:call system("pbcopy", getreg("\""))<CR>
nmap <C-v> :call setreg("\"",system("pbpaste"))<CR>p

" On ubuntu (running Vim in gnome-terminal)
" The reason for the double-command on <C-c> is due to some weirdness with the X clipboard system.
vmap <C-c> y:call system("xclip -i -selection clipboard", getreg("\""))<CR>:call system("xclip -i", getreg("\""))<CR>
nmap <C-v> :call setreg("\"",system("xclip -o -selection clipboard"))<CR>p
