# 问题描述丨Problem Description

Mac OS并不像大多数Linux发行版vi/vim默认自带语法着色高亮显示（通常Linux可通过编辑/etc/vimrc进行全局设置或~/vimrc进行单用户设置），使用vi/vim编辑文件时很不方便，如何解决 ?

Mac OS isn't like other most Linux distributions syntax highlighting is enabled by default(generally, edit /etc/vimrc to set global configuration or edit ~/vimrc for personal), this makes quite uncomfortable for using, but how to solve this case?

# 解决方案丨The Solution

Step 1，编辑文件/usr/share/vim/vimrc 丨 Edit file /usr/share/vim/vimrc

BobZhao@mac:~ > sudo vim /usr/share/vim/vimrcPassword:" Configuration file for vimset modelines=0         " CVE-2007-2438" Normally we use vim-extensions. If you want true vi-compatibility" remove change the following statementsset nocompatible        " Use Vim defaults instead of 100% vi compatibilityset backspace=2         " more powerful backspacing" Don't write backup file if vim is being called by "crontab -e"au BufWrite /private/tmp/crontab.* set nowritebackup" Don't write backup file if vim is being called by "chpass"au BufWrite /private/etc/pw.* set nowritebackup

Step 2, 在set backspace=2下插入如下配置 | configure the following chars under the line of 'set backspace=2'

set ai                  " auto indentingset history=100         " keep 100 lines of historyset ruler               " show the cursor positionsyntax on               " syntax highlightingset hlsearch            " highlight the last searched termfiletype plugin on      " use the file type plugins" When editing a file, always jump to the last cursor positionautocmd BufReadPost *\ if ! exists("g:leave_my_cursor_position_alone") |\ if line("'\"") > 0 && line ("'\"") <= line("$") |\ exe "normal g'\"" |\ endif |\ endif

Step 3，再次打开该文件（实际上任意文件都可以）会发现已自动着色，见下图。 | reopen the file(any file in fact) and you'll find the syntax highlighted automatically, see the following image.
