通过ARGV / ARGF接受多个命令行参数(Accept multiple command-line arguments through ARGV/ARGF)

 我试图让我的代码能够接受来自命令行输入的多个日志文件，以便根据不同的分隔符进行解析，并接受命令来解析某个日志文件的所有步骤。 
 
 它目前一次只能接受一个命令，它解析的日志文件是在代码中确定的，而不是变量@log_file下的命令行输入： 
 
@log_file = "07-07-14 to 07-13-14_debug.log"
@log_levels = ['DEBUG', 'INFO ', 'WARN ', 'ERROR', 'FATAL']

def error_sort
  @log_levels.each do |log_level|
    File.readlines(@log_file).each do |line|
      if (line =~ /<#{log_level}>/ .. line =~ /<(?!#{log_level}).+>/) && line !~ /<(?!#{log_level}).+>/
        File.open("#{log_level}.txt", "a") << line
      end
    end
  end
end

def read_log(step)
  File.readlines(@log_file).each do |line|
    if line.match /Recording dut_serial_number/
      File.open("step_#{step}", "a") << line
    elsif (line =~ /Beginning step ##{step} / .. line =~ /Beginning step #(?!#{step}).+ /) && line !~ /Beginning step #(?!#{step}).+ /
      File.open("step_#{step}", "a") << line
    else
      nil
    end
  end
end

command_line = ARGV[0..1]

ARGV.each do |num|
  if command_line == ["--step", "#{num}"]
    read_log("#{num}".to_i)
  elsif command_line == ["--sort"]
    error_sort
  else
    nil
  end
end
 
 思考？ 

I'm trying to get my code to be able to accept multiple log files from command-line input to parse through based on different delimiters as well as accept commands to parse through all the steps of a certain log file. 
 
It currently can only accept one command at a time and the log file it parses through is determined in the code, not the command-line input under the variable @log_file:
 
@log_file = "07-07-14 to 07-13-14_debug.log"
@log_levels = ['DEBUG', 'INFO ', 'WARN ', 'ERROR', 'FATAL']

def error_sort
  @log_levels.each do |log_level|
    File.readlines(@log_file).each do |line|
      if (line =~ /<#{log_level}>/ .. line =~ /<(?!#{log_level}).+>/) && line !~ /<(?!#{log_level}).+>/
        File.open("#{log_level}.txt", "a") << line
      end
    end
  end
end

def read_log(step)
  File.readlines(@log_file).each do |line|
    if line.match /Recording dut_serial_number/
      File.open("step_#{step}", "a") << line
    elsif (line =~ /Beginning step ##{step} / .. line =~ /Beginning step #(?!#{step}).+ /) && line !~ /Beginning step #(?!#{step}).+ /
      File.open("step_#{step}", "a") << line
    else
      nil
    end
  end
end

command_line = ARGV[0..1]

ARGV.each do |num|
  if command_line == ["--step", "#{num}"]
    read_log("#{num}".to_i)
  elsif command_line == ["--sort"]
    error_sort
  else
    nil
  end
end
 
Thoughts?
