From: verynewbie Date: 2006-06-09T07:29:13+09:00 Subject: directory name issue here is the code dirArray = Dir.entries(".") Dir.mkdir "SMITH, JOHN X755055" dirArray.each do fileentry = dirArray.pop if fileentry.match("txt") textfile = File.open(fileentry) textfile.each_line {|line| newdir = line.upcase.to_s if !File.exist?(newdir) Dir.mkdir "#{newdir}" print "Created directory: " + newdir + "\n" else print "Directory " + newdir + " already exists.. .\n" end } end end i have a text file in the same directory it has two lines, they look like this: SMITH, ADAM X755077 SMITH, ADAM X755078 when I run the above script, the first Dir.mkdir works fine however when it reads the first line of the text file, the Dir.mkdir "#{newdir}" doesn't create a directory i get this error mkdirs.rb:9:in `mkdir': Invalid argument - "SMITH, ADAM X755077" (Errno::EIN VAL) from mkdirs.rb:9 from mkdirs.rb:6:in `each_line' from mkdirs.rb:6 from mkdirs.rb:2:in `each' from mkdirs.rb:2 what am I doing wrong -- Posted via http://www.ruby-forum.com/.
