Hi there:
I want to create a directory and create files under it.
I can use
FileUtils.mkdir_p ARGV[0]
to create a directory, however if the directory already exist, program
will
generate error messages:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/fileutils.rb:243:in
`mkdir': File exists - ETFlist (Errno::EEXIST)

generate error messages:
How about posting what you want to do if the directory already exists?
If you want to overwrite it(=delete it), then first check if the
directory exists:
if File.exist?("dirname")
If it does, then:
if File.exist?("dirname")
FileUtils.remove_dir("dirname")
end
But that is playing with fire. You could end up deleting your whole
hard drive if you get the right file name in there. A safer option
would be to rename the old dir, and then create the new dir.
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)
