All  
This is embarrassing:  
How do I create a file?

# construct the log file name. It does not exist as yet.

lfil = leg\_dir+log\_name  
puts “Log file name is: #{lfil}”

# Create the file

if !File.exists?(lfil)  
puts “we entered file exixts condition”  
begin  
fOut = File.new(lfil, “w+”)  
fOut.puts(“Thomas the Tank”)  
rescue SystemCallError  
puts “failed to create new file”  
end  
end  
fOut.close unless fOut.nil?

I keep getting  
jusplay.rb:15:in `initialize': No such file or directory - D:/REINHARD/DEV/LOG/hello.log (Errno::ENOENT) from jusplay.rb:15:in`new’  
from jusplay.rb:15

Thanks

try “File.open” in stat of File.new (ka if it different)

check if File.writable?(File.dirname(lfil))

You need to make sure that the directory that will contain the file  
(D:/REINHARD/DEV/LOG/) exists before creating the file. You can either  
do that outside your script before you run it or from within your  
script:

require ‘fileutils’  
FileUtils.mkdir\_p(File.dirname(lfil))
