scan Command

Purpose

Produces a one line per message scan listing.

Syntax

scan [ +Folder ] [ Messages ] [ -form FormFile | -format String ] [ -noheader | -header ] [ -clear | -noclear ] [ -help ]

Description

The scan command displays a line of information about the messages in a specified folder. Each line gives the message number, date, sender, subject, and as much of the message body as possible. By default, the scan command displays information about all of the messages in the current folder.

If a + (plus sign) is displayed after the message number, the message is the current message in the folder. If a - (minus sign) is displayed, you have replied to the message. If an * (asterisk) is displayed after the date, the Date: field was not present and the displayed date is the last date the message was changed.

Flags
