一些配置文件备份

vim、tmux 配置文件的备份

vim

" All system-wide defaults are set in $VIMRUNTIME/debian.vim and sourced by
" the call to :runtime you can find below.  If you wish to change any of those
" settings, you should do it in this file (/etc/vim/vimrc), since debian.vim
" will be overwritten everytime an upgrade of the vim packages is performed.
" It is recommended to make changes after sourcing debian.vim since it alters
" the value of the 'compatible' option.

runtime! debian.vim

" Vim will load $VIMRUNTIME/defaults.vim if the user does not have a vimrc.
" This happens after /etc/vim/vimrc(.local) are loaded, so it will override
" any settings in these files.
" If you don't want that to happen, uncomment the below line to prevent
" defaults.vim from being loaded.
" let g:skip_defaults_vim = 1

" Uncomment the next line to make Vim more Vi-compatible
" NOTE: debian.vim sets 'nocompatible'.  Setting 'compatible' changes numerous
" options, so any other options should be set AFTER setting 'compatible'.
"set compatible

" Vim5 and later versions support syntax highlighting. Uncommenting the next
" line enables syntax highlighting by default.
if has("syntax")
  syntax on
endif

" If using a dark background within the editing area and syntax highlighting
" turn on this option as well
set background=dark

" Uncomment the following to have Vim jump to the last position when
" reopening a file
"au BufReadPost * if line("'\"") > 1 && line("'\"") <= line("$") | exe "normal! g'\"" | endif

" Uncomment the following to have Vim load indentation rules and plugins
" according to the detected filetype.
"filetype plugin indent on

" The following are commented out as they cause vim to behave a lot
" differently from regular Vi. They are highly recommended though.
set showcmd             " Show (partial) command in status line.
set showmatch           " Show matching brackets.
