Prev |  | Next

# delete

delete -- removes a history from memory only.

## Syntax

    (delete pattern)

## Parameters

`pattern`

  The name of one or more (using a globbing pattern) histories previously defined by the history command. When this parameter is not specified, the default is `*`, to include all histories.

## Returns

`t` (true) if successful, otherwise

        (error "No history matching pattern")

## Description

This command removes all memory associated with a given history, but does not remove any files on disk. It flushes the history to disk.

This command corresponds to the Cogent API function `HI_Delete` and the `hist_delete` dynamic library function.

## Example

        (delete p2)
        (delete p*)
