+======Synopsis:======
+[[on]] [<modes>]exec_prompt [<serial#>] [-|^]<match> { <action> }
+======Description:======
+This hook is triggered whenever an [[exec command|EXEC]]ed process displays a "prompt".
+More precisely, it is triggered when the process returns any line of
+output that is not terminated by a newline.  This is generally the case
+with interactive commands, such as nslookup(1).
+======Parameters:======
+|$0   |process number of name of the [[exec command|EXEC]]ed process          |
+|$1   |prompt string to look for                                              |
+======Default behavior:======
+If you do not suppress this event, the client will format the message
+and display it to your screen **UNLESS** you are redirecting the output
+of that [[exec]] to somewhere else.
+======Examples:======
+To hook the prompt when using nslookup interactively:
+   on ^exec_prompt "% >" {
+      assign foo $0
+      input "nslookup> " {
+         msg %${foo} $*
+      }
+   }
