You could use FileUtils.touch or just File.open a filename
in write-mode. You can take a look at the documentation for
those classes by typing

  ri FileUtils
  ri File

On your command-line.

Thank you.

Hi,

For an empty file, I guess the easiest way would be:

# Create a new file and write on it

···

#
begin
         f=File::open("test.txt","w")
rescue SystemCallError
         puts "Problem with File::open #1"
         #... something went wrong...
else
         f.close
end

# The file will be closed afterwards
#
begin
         File::open("/etc/test.txt","w") do | f |
                 # Do somethinf with "f" ...
         end
rescue SystemCallError
         # The file can't be created
         puts "Problem with File::open #2"
end

# If all you want is create an empty file...
#
begin
         File::open("test.txt","w") {}
rescue SystemCallError
         # The file can't be created
         puts "Problem with File::open #3"
end

read "ri IO::open" for more info!
