```
public TailCommand tail()
```
    Description copied from interface: Tail.Interface
    
    Reads the last 10 lines from the standard input and writes them to the standard output.
    
    Specified by:
    
    tail in interface Tail.Interface<TailCommand>
    
    Returns:
    the generic type <R> defined by the implementing class; the command itself returns no value and writes its result to the standard output; see class level parameter comments for more details
  - tail
```
public TailCommand tail(String... args)
```
    Description copied from interface: Tail.Interface
    
    Reads the last n lines from each of the files specified and writes them to the standard output. If more than a single file is specified, each file is preceded by a header consisting of the string "==> XXX <==" where "XXX" is the name of the file.
    Options can be specified by acronym (with a leading dash "-") or by long name (with two leading dashes "--"). Operands other than the default "--paths" operand have to be prefixed with the operand name.
    
    Specified by:
    
    tail in interface Tail.Interface<TailCommand>
    
    Parameters:
    args - String arguments defining the options and operands for the command. Options can be specified by acronym (with a leading dash "-") or by long name (with two leading dashes "--"). Operands other than the default "--paths" operand have to be prefixed with the operand name (e.g. "--count" for a subsequent count operand value).
    
    Returns:
    the generic type <R> defined by the implementing class; the command itself returns no value and writes its result to the standard output; see class level parameter comments for more details
  - tail
```
public TailCommand tail(long count)
```
    Description copied from interface: Tail.Interface
    
    Reads the last count lines from the standard input and writes them to the standard output.
    
    Specified by:
    
    tail in interface Tail.Interface<TailCommand>
    
    Parameters:
    count - The last count lines of each input file are copied to standard output, starting from 1 (characters instead of lines if the -c option is specified, and offset from start instead of end with -s option). Must be a non-negative integer or an exception is thrown. If count is greater than the number number of lines (characters) in the input, the application will not error and send the whole file to the output.
    
    Returns:
    the generic type <R> defined by the implementing class; the command itself returns no value and writes its result to the standard output; see class level parameter comments for more details

```
public TailCommand tail(File... files)
```
    Description copied from interface: Tail.Interface
