ruby 去掉文件里重复的行

程序员文章站 2022-06-17 22:43:56
old = file.open(argv[0]).collect new = file.open(argv[1],"a+") for i in 0..old.length-...
old = file.open(argv[0]).collect
new = file.open(argv[1],"a+")
for i in 0..old.length-1
new.write(old.uniq[i])
end

##或简单两行也可以如qc.rb

old = file.open(argv[0]).collect
puts old.uniq

然后qc.rb dic.dic >new.dic
