This actually copies the last 1000 entries to a new database, and then replaces the old file with the new. Use the `--keep=` argument to specify a number other than 1000. a Clear the IPython history database, deleting all entries. Because this is a destructive operation, IPython will prompt the user if they really want to do this. Passing a `-f` flag will force clearing without a prompt.
