Commands Reference, Volume 5

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

-clear Clears the display after sending output. The scan command uses the values of the $TERM environment variable to determine how to clear the display. If standard output is not a display, the scan command sends a form feed character after sending the output.
+Folder Specifies which folder to scan. The default is the current folder.
-form FormFile Displays the scan command output in the alternate format described by the FormFile variable.
-format String Displays the scan command output in the alternate format described by the String variable.
-header Displays a heading that lists the folder name and the current date and time.
-help Lists the command syntax, available switches (toggles), and version information.

Note: For Message Handler (MH), the name of this flag must be fully spelled out.
