@cindex Deleting hung user sessions

@command{radzap} searches the Radius accounting database for matching login
records and closes them.

At least one of the options @option{-n}, @option{-p}, or the user name must be
specified. If they are used in conjunction, they are taken as if
joined by the logical @sc{and} operation.

@command{radzap} operates in two modes: silent and confirm. The silent
mode is enabled by default. When run in this mode, @command{radzap} deletes
every record that matches the search conditions given.

In confirm mode @command{radzap} will ask for a confirmation
before zapping each matching record. Any line beginning with a @samp{y}
is taken as a positive response; any other line is taken as a negative
response.

The confirm mode is toggled by the command line option @option{-c}.
