   6 #A pure shell script to find dead symlinks and output them quoted
   7 #so they can be fed to xargs and dealt with :)
   8 #eg. broken-link.sh /somedir /someotherdir|xargs rm
   9 #
  10 #This, however, is a better method:
  11 #
  12 #find "somedir" -type l -print0|\
  13 #xargs -r0 file|\
  14 #grep "broken symbolic"|
  15 #sed -e 's/^\|: *broken symbolic.*$/"/g'
  16 #
  17 #but that wouldn't be pure bash, now would it.
  18 #Caution: beware the /proc file system and any circular links!

vim中导出语法高亮的文件：

:runtime! syntax/2html.vim

它本身并不是语法文件，只是一个把当前窗口转换成 HTML 的脚本。Vim 打开一个新窗 口，在那里它构造 HTML 文件
