- Method Detail
  - exec
```
public static String exec(File workingDirectory,
                          PrintStream err,
                          PrintStream out,
                          String... args)
```
    Executes a program. This is a convenience method mainly to be able to catch the output of programs as shell scripts can do by wrapping calls in $(...).
    
    Parameters:
    
    workingDirectory - the directory in which to execute the program
    
    err - the PrintStream to print the program's error stream to; if null is passed, the error goes straight to Nirvana (not the band, though).
    
    out - the PrintStream to print the program's output to; if null is passed, the output will be accumulated into a String and returned upon exit.
    
    args - the command-line to execute, split into components
    
    Returns:
    
    the output of the program if out is null, otherwise an empty String
    
    Throws:
    
    RuntimeException - if interrupted or the program failed to execute successfully.
  - exec
```
public static String exec(File workingDirectory,
                          InputStream in,

    Executes a program. This is a convenience method mainly to be able to catch the output of programs as shell scripts can do by wrapping calls in $(...).
    
    Parameters:
    
    workingDirectory - the directory in which to execute the program
    
    in - the InputStream which gets fed to the program as standard input;
    
    err - the PrintStream to print the program's error stream to; if null is passed, the error goes straight to Nirvana (not the band, though).
    
    out - the PrintStream to print the program's output to; if null is passed, the output will be accumulated into a String and returned upon exit.
    
    args - the command-line to execute, split into components
    
    Returns:
    
    the output of the program if out is null, otherwise an empty String
    
    Throws:
    
    RuntimeException - if interrupted or the program failed to execute successfully.
