"BashDiff adds commands that help you manipulate positional parameters, often with much greater efficiency than the normal bash routes. The pcursor command lets you manipulate the current positional parameters as a single group, clearing them all and storing and restoring them all from a stack. New commands prefixed with pp_ help you manipulate the positional parameters themselves. These commands all take an optional -a parameter to let you specify the name of an array to use instead of working on the implicit positional parameters array. For example, the normal bash command to append to the positional parameters is shown below with the BashDiff equivalent below it."
