Subject: Re: Creating directory and its files

You mention me it's safe to create a directory with date version
like directory_yy_mm_dd

i can get date by

time=Date.today()

but how to connect the directory name with the time?

I use

FileUtils.mkdir_p ARGV[0]+time

but there is an error message:

test2.rb:61:in `+': can't convert Date into String (TypeError)
