再帰してディレクトリ内のファイルの行数を個別に表示する

Last updated at Posted at 2019-10-02

末尾が _spec のファイルは除外している

# 全ファイルの行数を吐き出すlinuxコマンド (rubyはバッククォートにするとシェルを直接実行できる)
`for file in $(find . -name "*.rb"); do wc -l $file; done > ./tmp/lines.txt`
  open('./tmp/lines.txt', 'r') { |f| f.inject([]) { |r, l| r << l.split(" ") } }.sort{|a, b| a[0].to_i <=> b[0].to_i }.each {|i| puts i.join(" : ") unless i[1] =~ /_spec/  }
  

よくよく考えたらシェル使わずに Dir.glob でパス取ってきてやるでもよかったな...
