# count

count -- counts the number of histories that match a pattern.

## Syntax

    (count [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

The number of histories (`n`) that match the specified `pattern`, in this format:

        (count pattern n)

## Description

This command queries the Cascade Historian for the total number of histories currently being kept that match the given pattern.

This command corresponds to the Cogent API function `HI_Count` and the `hist_count` dynamic library function.

## Example

        [sh]$ lsend Hist
        Hist> (count p*)
        (count p* 5)
        Hist>
