Ruby语言的用途比较广泛，可以轻松灵活的帮助我们实现许多功能需求。编程人员可以很容易熟悉这项语言的应用。在这篇文章中，我们为大家带来了Ruby输出文件信息的一些技巧应用。#t#

数据是随机的，所以每次的记录都会不同。

Ruby输出文件信息代码示例：

1. #!/usr/bin/envruby
2. COUNT=10
3. require'benchmark'
4. $account_chars=('A'..'Z').
   to_a.delete_if{|c|c=~/[AEIOUY]/}
5. #$password_chars=('0'..'9').to_a
6. $password_chars=Array.new
7. $password_chars[0..9]=('0'..'9').to_a
8. $password_chars[10..36]=('A'..'Z').to_a
9. defaccount_char
10. $account_chars[rand($account_chars.length)]
11. end
    
12. defpassword_char
13. $password_chars[rand($password_chars.length)]
14. end
15. defaccount_chars
16. account_chars=[]
17. 6.times{|c|account_chars
    <<account_char}
18. account_chars
19. end
20. defpassword
21. begin
22. begin
23. password=''
24. password<<password_char
25. endwhilepassword=='0'
26. 4.times{password<<password_char}
27. endwhilepassword=~/^(.)1111$/
28. password
29. end
30. accounts={}
31. lines=[]
32. putsBenchmark::CAPTION
33. putsBenchmark.measure{
34. COUNT.timesdo
35. i=0
36. account_chars.inject(accounts)do|a,c|
37. i+=1
38. i==6?a[c]=password:a[c]||={}
39. end
40. end
41. }
42. putsBenchmark.measure{
43. accounts.eachdo|char,chars|
44. account=[char]
45. chars.eachdo|char,chars|
46. account<<char
47. chars.eachdo|char,chars|
48. account<<char
49. chars.eachdo|char,chars|
50. account<<char
51. chars.eachdo|char,chars|
52. account<<char
53. chars.eachdo|char,password|
54. account<<char
55. lines<<"#{account.join}t#
    {password}rn"
56. account.pop
57. end
58. account.pop
59. end
60. account.pop
61. end
62. account.pop
63. end
64. account.pop
65. end
66. end
67. }
68. putsBenchmark.measure{
69. open'account.txt','wb'do|f|
70. f.printlines.delete_at(rand(lines.length))
    untillines.empty?
71. end
72. }

运行后输出到： account.txt文件中。

Ruby输出文件信息格式如下：
