find the last accessed date of a csv file in ruby

To find the last accessed date of a CSV file in Ruby, you can use the File::Stat class which represents the status information of a file. The atime method of File::Stat returns the last accessed time of the file.

Here's an example code to get the last accessed date of a CSV file:

main.rb
require 'csv'

file_path = '/path/to/file.csv'

# Get the last accessed time of the file
last_accessed_time = File.stat(file_path).atime

# Convert the time to a human-readable format
formatted_time = last_accessed_time.strftime('%Y-%m-%d %H:%M:%S')

puts "Last accessed on: #{formatted_time}"
294 chars
12 lines

In this example, we first require the standard CSV library of Ruby. Then, we define the file path of our CSV file. We use the File.stat method to get the status information of the file and then call the atime method to get the last accessed time. Finally, we format the time into a human-readable string using strftime method and print it to the console.

Note that the atime method returns the time with the system's timezone, so the output may differ on different systems.
