The manual page and help for the tail linux command. This manual page describes the GNU version of the tail command. The tail command prints the last lines of the specified file (s) (10 lines are the default); reads from standard input if no file is specified or if the file name is followed by a '-'. If more than one file is specified, it prints a header containing the file name enclosed in `==> 'and` <==' before the outputs of the other files.
