Dear Friends, in Linux Fedora10, I sort the file aaa.txt : Cari figliozzi Cari figlipucci Cari figli, oggi Cari figli, ieri Cari figli, domani Cari figli, pregate Cari figlioli with the command: <...> sort < aaa.txt > bbb.txt and I obtain the file bbb.txt Cari figli, domani Cari figli, ieri Cari figli, oggi Cari figlioli Cari figliozzi Cari figli, pregate Cari figlipucci which doesn't look sorted according to my expectation. Then, in WindowsXP, I sort again the file aaa.txt with the command: <...> sort aaa.txt > ccc.txt and I get the file ccc.txt : Cari figli, domani Cari figli, ieri Cari figli, oggi Cari figli, pregate Cari figlioli Cari figliozzi Cari figlipucci which looks sorted as expected. Should I use in Fedora some sort option or I met a bug? Thanks for your attention and best regards Vito Di Blas Ivrea Italy vito.diblas@libero.it
