type | string | File Type settings. | False
client | string | The p4 client spec to use. The default is the current client. | False
failonerror | bool | Determines if task failure stops the build, or is just reported. The default is true. | False
if | bool | If true then the task will be executed; otherwise, skipped. The default is true. | False
port | string | The p4 server and port to connect to. The default is "perforce:1666". | False
script | bool | Prepends a descriptive field (for example, text:, info:, error:, exit:) to each line of output produced by a Perforce command. This is most often used when scripting. The default is false. | False
timeout | int | The maximum amount of time the application is allowed to execute, expressed in milliseconds. Defaults to no time-out. | False
unless | bool | Opposite of `if`. If false then the task will be executed; otherwise, skipped. The default is false. | False

### Framework-configurable parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
useruntimeengine | bool | Specifies whether the external program should be executed using a runtime engine, if configured. The default is false. | False

### Nested Elements:

#### <arg>

The command-line arguments for the external program.

Represents a command-line argument.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
dir | directory | The value for a directory-based command-line argument; will be replaced with the absolute path of the directory. | False
file | file | The name of a file as a single command-line argument; will be replaced with the absolute filename of the file. | False
if | bool | Indicates if the argument should be passed to the external program. If true then the argument will be passed; otherwise, skipped. The default is true. | False
line | string | List of command-line arguments; will be passed to the executable as is. | False
path | <path> | The value for a PATH-like command-line argument; you can use `:` or `;` as path separators and NAnt will convert it to the platform's local conventions, while resolving references to environment variables. | False
unless | bool | Indicates if the argument should not be passed to the external program. If false then the argument will be passed; otherwise, skipped. The default is false. | False
value | string | A single command-line argument; can contain space characters. | False

### Nested Elements:

#### <path>

Sets a single command-line argument and treats it like a PATH - ensures the right separator for the local platform is used.

#### </path>

### Examples

- A single command-line argument containing a space character.

      <arg value="-l -a" />

- Two separate command-line arguments.

      <arg line="-l -a" />

- A single command-line argument with the value `\dir;\dir2;\dir3` on DOS-based systems and `/dir:/dir2:/dir3` on Unix-like systems.

      <arg path="/dir;/dir2:\dir3" />

#### </arg>

### Examples

- Move the specified files matching the view into the "New" changelist.

      <p4reopen view="//Root/...Version.xml" changelist="New" />

- Modify the specified files matching the view to the given file type. The change won't affect the repository until submitted.

      <p4reopen view="//Root/...*.res" type="binary" />
