find the name of a csv file in ruby

Here's an example code block in Ruby that shows how to find the name of a CSV file:

main.rb
# Example CSV filename
filepath = "path/to/file.csv"

# Split the filepath string by forward slashes and take the last string element
filename = filepath.split("/").last

# Split the filename string by dots and take the first string element
name = filename.split(".").first

puts name # Output the name of the CSV file (without the file extension)
348 chars
11 lines

This code block first defines a file path filepath string. Next, it splits the filepath string by forward slashes (/) using the split method, then takes the last element of the resulting array using the last method. This gives us the filename string.

Finally, it splits the filename string by dots (.) using the split method, then takes the first element of the resulting array using the first method. This gives us the name of the CSV file (without the file extension). The puts method is used to output the name of the CSV file to the console.
