Method Details

runNative

public static List<String> runNative(String cmdToRun)

Executes a command on the native command line and returns the result. This is a convenience method to call Runtime.exec(String) and capture the resulting output in a list of Strings. On Windows, built-in commands not associated with an executable program may require cmd.exe /c to be prepended to the command.

Parameters:

cmdToRun - Command to run

Returns:

A list of Strings representing the result of the command, or empty string if the command failed

runNative

public static List<String> runNative(String[] cmdToRunWithArgs)

Executes a command on the native command line and returns the result line by line. This is a convenience method to call Runtime.exec(String[]) and capture the resulting output in a list of Strings. On Windows, built-in commands not associated with an executable program may require the strings cmd.exe and /c to be prepended to the array.

Parameters:

cmdToRunWithArgs - Command to run and args, in an array

Returns:

A list of Strings representing the result of the command, or empty string if the command failed

runNative

public static List<String> runNative(String[] cmdToRunWithArgs,
 String[] envp)

On Windows, built-in commands not associated with an executable program may require the strings cmd.exe and /c to be prepended to the array.

Parameters:

cmdToRunWithArgs - Command to run and args, in an array

envp - array of strings, each element of which has environment variable settings in the format name=value, or null if the subprocess should inherit the environment of the current process.

Returns:

A list of Strings representing the result of the command, or empty string if the command failed
