I think I found a bug in GNU tail. What do you folks think? I have some shell scripts that were written by a third party in 2002 or so. There are these two commands: head -219554 tokenized > ../eng.train tail +219555 tokenized > ../eng.testa The first one works on F7; the second one errors out: tail: cannot open `+219555' for reading: No such file or directory This is supposed to be valid syntax: "If any option-argument is a number n starting with a ‘+’, tail begins printing with the nth item from the start of each file, instead of from the end." http://www.gnu.org/software/coreutils/manual/html_node/tail-invocation.html So, bug or no bug? And is it just funny on F7 or can you repro it elsewhere?
