- Constructor Detail
  - DefaultUnix4jCommandBuilder
```
public DefaultUnix4jCommandBuilder()
```
    Default constructor initialized with a NoOp command which will be replaced by the first command joined to this builder's command chain. Uses a DefaultExecutionContext to execute commands.
  - DefaultUnix4jCommandBuilder
```
public DefaultUnix4jCommandBuilder(ExecutionContextFactory contextFactory)
```
    Constructor using the specified factory to create contexts for command execution. The builder is initialized with a NoOp command which will be replaced by the first command joined to this builder's command chain.
    
    Parameters:
    
    contextFactory - the factory used to create execution contexts that are passed to the execute method when a command is executed
- Method Detail
  - cat
```
public Unix4jCommandBuilder cat()
```
    Description copied from interface: Unix4jCommandBuilder
    
    Reads the lines from the standard input and writes them to the standard output.
    Note that the method returns this builder to allow for command chaining. The command itself is returned by the CommandBuilder.build() method. See class comments for more information.

    Specified by:
    
    cat in interface Cat.Interface<Unix4jCommandBuilder>
    
    Returns:
    
    this builder to allow for method chaining; method chaining is used here to create command chains; adding a command to the chain usually means that the previous command pipes its output to the next command (the pipe symbol in unix)
  - cat
```
public Unix4jCommandBuilder cat(String... args)
```
    Description copied from interface: Unix4jCommandBuilder
    
    Reads the lines from files specified as arguments and writes them to the standard output. Options can be specified by acronym (with a leading dash "-") or by long name (with two leading dashes "--"). File arguments are expanded if wildcards are used. All file arguments are processed in command-argument order.
    Note that the method returns this builder to allow for command chaining. The command itself is returned by the CommandBuilder.build() method. See class comments for more information.

```
    Description copied from interface: Unix4jCommandBuilder

    Sorts, merges, or sequence checks the lines the lines of all the specified files together and writes the result to the standard output.
    Comparisons are based on the entire line without line ending. The collating sequence of the current locale is used to perform the comparisons.
    The sort algorithm used is guaranteed to be stable: lines considered equal will not be reordered as a result of the sort. If two lines originate from different input files, the index of the file in the input arguments list defines the ordering of the lines.
    Note that the method returns this builder to allow for command chaining. The command itself is returned by the CommandBuilder.build() method. See class comments for more information.

    Description copied from interface: Unix4jCommandBuilder
    
    Reads from the standard input and compares adjacent lines, writing one copy of each input line to the standard output. The second and succeeding copies of repeated adjacent input lines are not written to the output.
    Note that repeated lines in the input are not detected if they are not adjacent (see --global or -g option); sorted input lines always result in unique output lines.
    Note that the method returns this builder to allow for command chaining. The command itself is returned by the CommandBuilder.build() method. See class comments for more information.

```
public Unix4jCommandBuilder xargs(String delimiter,
                                  int maxArgs)
```
    Description copied from interface: Unix4jCommandBuilder
    
    Reads items from the standard input using the specified delimiter to separate items, and provides variables for the items read from the standard input. The command following after xargs is executed once for every maxArgs items read from the standard input (or possibly fewer for the last invocation with the remaining items at the end of the file). The item variables are usually passed to the invoked command as arguments.
    Note that the method returns this builder to allow for command chaining. The command itself is returned by the CommandBuilder.build() method. See class comments for more information.

  - join
```
public Unix4jCommandBuilder join(Command<?> command)
```
    Description copied from interface: CommandBuilder
    
    Adds the specified command to the chain of commands held by this builder. Application code rarely needs to call this method directly; the command specific methods are usually called instead to join an instance of a certain command, e.g. one of the grep(..) methods to join a grep command.
    If this is the fist joined command, the builder builds this command and returns or executes it if CommandBuilder.build() or toXXX(..) is called, respectively. If the command argument joins already existing commands, the last command in the chain redirects its output to the standard input of the specified command.
    
    Specified by:
    
    join in interface CommandBuilder
    
    Specified by:
    
    join in interface Unix4jCommandBuilder
    
    Overrides:
    
    join in class DefaultCommandBuilder
    
    Parameters:
    
    command - the command to join the last previously joined command
    
    Returns:
    
    the builder for chained method invocation to join other commands
  - apply
```
public Unix4jCommandBuilder apply(LineOperation operation)
```
    Description copied from interface: CommandBuilder
    
    Adds a new command based on the specified operation and adds it to the chain of commands held by this builder.
    If this is the fist joined command, the builder builds the command created from the operation and returns or executes it if CommandBuilder.build() or toXXX(..) is called, respectively. If the command argument joins already existing commands, the last command in the chain redirects its output to the standard input of the specified command.
    
    Specified by:
    
    apply in interface CommandBuilder
    
    Specified by:
    
    apply in interface Unix4jCommandBuilder
    
    Overrides:
    
    apply in class DefaultCommandBuilder
    
    Parameters:
    
    operation - the operation on which the added command is based
    
    Returns:
    
    the builder for chained method invocation to join other commands
  - reset
```
public Unix4jCommandBuilder reset()
```
    Description copied from interface: CommandBuilder
    
    Resets this command builder to its initial state. All joined commands are removed from the command chain leaving the builder in a state to build a NoOp command. New commands can be joined subsequently to create a new command chain.
    
    Specified by:
