Exerpt from bash documentation. HISTORY EXPANSION The bash shell supports a history expansion feature that is similar to the history expansion in csh. This feature is enabled by default for interactive shells, and can be disabled using the +H option to the set builtin command. Non-interactive shells do not perform history expansion by default. History expansions introduce words from the history list into the input stream, making it easy to repeat commands, insert the arguments to a previous command into the current input line, or fix errors in previous commands quickly. History expansion is performed immediately after a complete line is read, before the shell breaks it into words. It takes place in two parts. The first is to determine which line from the history...

There are two variables you can use while writing command line applications with PHP - $argc and $argv : $argc is the number of arguments plus one (the name of the script running). $argv is an array containing the arguments, starting with the script name as number zero ( $argv[0] ). Example: #!/usr/bin/php <?php var_dump($argv); ?>

Starting with JDK1.5, Java allowed variable arguments (varargs) to methods. You use three dots after the final parameter type to indicate that variable number of arguments may be passed. Varargs can only be used in the final argument position. For example: static int sum (int ... numbers) { int total... Some examples from the Java API: java.text.MessageFormat: public static String format(String pattern, Object... java.lang.String: public static String format(String format, Object.... java.lang.ProcessBuilder: public ProcessBuilder(String... command)
