Assign text from file to variable in Ruby without returning text

Question

I am trying to parse some access logs with Ruby, the file itself is 363MB. I'm working in IRB and when I try to assign the text from the document to a variable data = logs.read it begins returning all the text into the interpreter, which at 363MB is an issue.

How do I assign the contents of a file to a variable without returning the value back in the interpreter?

Answer 1

Start your irb as below :

irb --simple-prompt --noecho

• --simple-prompt is to get the IRB prompt as >>
• --noecho is to off the echo on IRB

Here is an example:

C:\>irb --simple-prompt
>> x = 2
=> 2
>> exit

C:\>irb --simple-prompt --noecho
>> x = 2
>>
