NAME    [Toc]    [Back]

       scan  -  produce a one-line-per-message scan listing (only
       available within the message handling system, mh)

SYNOPSIS    [Toc]    [Back]

       scan [+folder] [msgs] [options]

OPTIONS    [Toc]    [Back]

       Directs scan to clear the screen. If the -clear switch  is
       used  and  the  output  of scan is directed to a terminal,
       then scan consults the $TERM  and  $TERMCAP  environmental
       variables to determine your terminal type in order to find
       out how to clear the  screen  prior  to  exiting.  If  the
       -clear  switch  is  used  and  the  output  of scan is not
       directed to a terminal, then scan sends a  formfeed  prior
       to  exiting.   Re-formats  the output of scan according to
       the instructions in the named file. The  named  formatfile
       must  be  in  mh-format  style;  see mh-format(4) for more
       details.  Re-formats the output of scan according  to  the
       instructions  in  the  string given. The string must be in
       mh-format style; see mh-format(4) for  more  details.  You
       must  place  the string argument to this command in double
       quotes (").  Produces a header  line  prior  to  the  scan
       listing.  The  header line displays the name of the folder
       and the date and time. This can be  suppressed  using  the
       -noheader  option.   Prints a list of the valid options to
       this command.  Lists  the  output  from  scan  in  reverse
       order,  from the highest message number to the lowest. The
       -noreverse option lists messages in the conventional  way,
       from  lowest to highest numbers.  The -noreverse option is
       the default.  Specifies  the  width  of  your  screen,  in
       columns.

       The defaults for this command are as follows:

       +folder defaults to the current folder
       msgs defaults to all
       -noheader
       -width  defaults to the width of the terminal

DESCRIPTION    [Toc]    [Back]

       The  scan  command produces a one-line-per-message listing
       of the messages in the current folder.

       You can scan a folder other than  the  current  folder  by
       using  the +folder argument. You can use the msgs argument
       to produce a scan listing of a number  of  messages  or  a
       range  of  messages  in the specified folder. You can also
       use scan in conjunction with a message sequence defined by
       mark   or  pick.  See  mark(1)  for  more  information  on
       sequences.

       Each scan line contains the message number, the date,  the
       From: field, the Subject: field, and, if room allows, some
       of the body of the message. The current message is  marked
       with a plus sign (+).

       The scan command actually reads each of the specified messages
 and parses them to extract the  desired  fields.  If
       format  errors  are  found  in  any of the messages during
       parsing, scan produces appropriate error messages.

       Because MH has been configured with the BERK option,  scan
       has  two  additional  options: -reverse and -noreverse. In
       addition, scan updates the MH context  prior  to  starting
       the listing, so interrupting a long scan listing preserves
       the new context. The default configuration  file  that  is
       supplied with MH has the BERK option enabled.

       If  scan  encounters  a message without a Date: field, the
       date is filled in with the last write date of the message,
       and  an asterisk (*) is appended. This is useful for identifying
 unsent message drafts. Unsent drafts are not  usually
  allowed  to  contain  a  Date: field, and are consequently
 marked with an asterisk in scan listings.

EXAMPLES    [Toc]    [Back]

       The following example produces a listing  of  messages  11
       through 15 in the folder +inbox : % scan +inbox 11-15
         11   18/01  ralph              Project Plan Meeting Monday<<This

          12 -21/01 johnson             squash<<Thought  i  might
       postpone

       conversion

       of mail
          15+  21/01 calvin@hobbes.uuc  Re: new forum for discussion
 of m

       In this listing, the plus sign (+) on message 15 indicates
       that  it is the current message. The hyphen (-) on message
       12 indicates that you have replied to the message.  It  is
       produced  by the -annotate option to repl; see repl(1) for
       more information. If there is sufficient room left on  the
       line after the subject, scan fills the line with text from
       the body, preceded by <<, and terminated by >> if the body
       is sufficiently short.
