It would depend on what was delimited by the tabs.

You might try:

x = File.read("data.text")
x.sub!(%r{.*\n}, '#')

This reads the contents of the file into a string, and turns it into
a hash (#).

You can try

filename = "my_tab_delimeted_file.txt"

File.readlines(filename).each do |line|
line.split("\t").each do |item|
puts item
end
end

Assuming you mean each line contains a key and a value separated by a
tab, you can do something like

results = Hash.new

File.open "your_file.txt" do |f|
f.each_line do |l|
key, value = l.chomp.split("\t")
results[key] = value
end
end

p results

That's nice. What do you want the hash to look like?

What you show here is not the sort of thing a hash is usually much good at,
because a hash is key/value *pairs*, and you appear to have triplets.
