fromto -- sendmail logfile viewer

SYNOPSIS

       fromto [-f]    [-q]   [-#]   [-from string]   [-to string]
              [-sleep time]      [-show items]      [+show items]
              [-ignore items] [logfiles...]

DESCRIPTION

       Fromto  prints  the  sendmail logfile information in human
       readable format.   Logfiles  are  usually  placed  in  the
       ``/usr/spool/mqueue'' directory.

       If  files  are specified in the command line, fromto reads
       data from those files. Otherwise  the  default  files  are
       used.

       When  SIGQUIT  is  sent, fromto prints a list of currently
       deferred messages.  This is convenient when  running  with
       the -f option.

       Default  items  to  be displayed can be changed by setting
       the environment variable `FROMTO'.

       You need the Perl 3.0 programming  language  to  run  this
       command.

       Options:

       -f     Works like ``tail -f''.  Continue to read data file
              after encountering eof.

       -q     Start up quietly.  Fromto displays  no  information
              when  reading existing files.  It begins to display
              after encountering  the  first  eof.   This  option
              doesn't make sense when used without -f option.

       -#     Any  digit can be used here.  This number means how
              many files are to be read. Usually the syslog  file
              is renamed by cron every night. If this number is 1
              (default), it reads only from the file named syslog
              in  the  logging  directory.  If 2 is specified, it
              reads from syslog.0 and syslog.

       -from string
              Display information only when  from  field  matches
              the string.  Conditional options, -from and -to are
              evaluated in logical OR manner by default.

       -to string
              Display information only when to field matches  the
              string.

              between -from and -to is easy to read.  For example
              next command line will only print messages from foo
              to bar.

                     fromto -from foo -a -to bar


       -sleep time
              Specify  the interval in seconds between reads when
              running with the -f option.  Default is 5  seconds.

       -show items
              Specify  what  kind  of  information  is to be dis-
              played.  Items is a string  which  contains  alpha-
              betic  characters which represent a kind of data in
              the following manner.  Default is ``SOUE''.

              S  Mail is sent.  From and to fields are  connected
                 by arrow (->).
              D  Mail  is deferred or queued.  From and to fields
                 are connected by two asterisks (**).
              I  ID number
              M  Message ID
              E  Error information
              O  Status other than Sent or Deferred.  Fields  are
                 separated  by  two  question characters (??) and
                 followed by status string.
              L  Sendmail locked
              U  Unrecognized message
              d  Delayed time
              A  Show all items

       +show items
              Add items to items string.

       Because this program doesn't release memory,  the  process

       The syslog file format can vary from machine  to  machine.
