Method Detail

cd

public CdCommand cd()

Description copied from interface: Cd.Interface

Changes the current directory to the user home directory as defined by the execution context (usually the directory specified by the "user.home" system property).

Specified by:

cd in interface Cd.Interface<CdCommand>

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

cd

public CdCommand cd(File file)

Description copied from interface: Cd.Interface

The current working directory is changed to the given file. If the specified file argument does not represent a valid directory, an exception is thrown. Note that relative paths are not resolved with the (old) current working directory. Use the String path to enable relative path resolving and wildcards.

Specified by:

cd in interface Cd.Interface<CdCommand>

Parameters:

file - the file to use as input; relative paths are not resolved (use the string path argument to enable relative path resolving based on the current working directory).

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

cd

public CdCommand cd(String path)

Description copied from interface: Cd.Interface

The current working directory is changed to the given file. Relative paths are resolved on the basis of the (old) current working directory. Wildcards are possible if the first matching file represents a directory. If the first file specified by the given path argument is not a valid directory, an exception is thrown.

Specified by:

cd in interface Cd.Interface<CdCommand>

Parameters:

path - the directory to become the new current working directory; wildcards * and ? are supported; relative paths are resolved on the basis of the current working directory.

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
