For example: Saving all file names in directory to file: echo * > /some/file as a result I get 'aa aa bb bb' Which files are in current directory? 1) 'aa aa', 'bb bb' 2) 'aa' 'bb' 'aa bb' 3) your sugggestion PS. ugly behaviour to my mind or unclean spec/docs maybe -- С уважением, Eugen mailto:kes-kes@yandex.ru
