I have a simple script that does some search and replace. This is basically it:
File.open("us_cities.yml", "r+") do |file|
while line = file.gets
"do find a replace"
end
"Here I want to write to a new file"
end
As you can see I want to write a new file with the output. How can I do this?
Outputting to a new file can be done like this (don't forget the second parameter):
output = File.open( "outputfile.yml","w" )
output << "This is going to the output file"
output.close
So in your example, you could do this :
File.open("us_cities.yml", "r+") do |file|
while line = file.gets
"do find a replace"
end
output = File.open( "outputfile.yml", "w" )
output << "Here I am writing to a new file"
output.close
end
If you want to append to the file, make sure you put the opening of the output file outside of the loop.
First you have to create a new file such as newfile.txt
Then change the script to
File.open("us_cities.yml", "r+") do |file|
new_file = File.new("newfile.txt", "r+")
while line = file.gets
new_file.puts "do find a replace"
end
end
This will make a new file with the output
