Writing a file, without deleting it's current content

Ruby
1

Hi, I just read about the “.write” method.
Let’s say that I’ve just written a string to a file, “file.txt”. Then I
want
to add some more information to it, on the next line. I use .write again
and
my info got replaced. How do I add to the without deleting what’s
already in
it. I know I can load the string from it and then add them together, but
isn’t there a smarter way to do it, like writing to the next line?

Thanks in advance :slight_smile:

Look up the “append” option for File when opening for writing.

ok just to make sure I got it right:

File.open(“myFile.txt.”, APPEND=“This is the string I’m writing” )

Correct?

erm, try this:

myfile = File.open(“myFile.txt”,“a”)
myfile << “This is the string I’m writing”
