Today, I was working on a script at work where I ultimately needed to export a 2MB file and although this isn’t a large file, I know I will forget about getting rid of it so while searching around, I came across tempfile.
Tempfile simply will be garbage collected at some time because the file is stored in
/tmp and you can make your own copy if you need it. Here’s an example from the ruby docs:
require 'tempfile' file = Tempfile.new('foo') file.path # => A unique filename in the OS's temp directory, # e.g.: "/tmp/foo.24722.0" # This filename contains 'foo' in its basename. file.write("hello world") file.rewind file.read # => "hello world" file.close file.unlink # deletes the temp file
Make sure to run
file.unlink if you want it to be deleted right away.
