用PowerShell统计关键词

本来开始打算大干一场的，结果发现区区4行代码搞定了。原来用PowerShell统计关键词这么欢乐啊。

$wordBreakers = ",. ()\\/';-<>_#"
$wordTemplate = '^Pub\w+'
cd D:\Dropbox\workdir\LandiStore\BOCISTDemo\src\Project

$content = (dir *.c -Recurse | % { cat $_} ) -join "`n"
$words = $content.Split($wordBreakers)
$words = $words | ? {$_ -Match $wordTemplate}
#$words | sort -Unique
$words | group | sort count -Descending | select Name, Count
