🗃️ Using Tempfile for Safe Temporary Files

Tempfile creates and cleans up temporary files securely. It avoids name collisions and automatically deletes the file when it’s closed or the program exits.

require 'tempfile'

tmp = Tempfile.new('data')
tmp.write("temporary data")
tmp.rewind
puts tmp.read

tmp.close
tmp.unlink  # deletes the file
