 NAME
      fwtmp, wtmpfix - manipulate connect accounting records

 SYNOPSIS
      /usr/lib/acct/fwtmp [-ic]
      /usr/lib/acct/wtmpfix [files]

 DESCRIPTION
    fwtmp
      fwtmp reads from the standard input and writes to the standard output,
      converting binary records of the type found in wtmp to formatted ASCII
      records.  The ASCII version is useful to enable editing, via ed(1),
      bad records or general purpose maintenance of the file.

      The argument -ic is used to denote that input is in ASCII form, and
      output is to be written in binary form.  (The arguments i and c are
      independent, respectively specifying ASCII input and binary output,
      thus -i is an ASCII to ASCII copy and -c is a binary to binary copy).

    wtmpfix
      wtmpfix examines the standard input or named files in wtmp format,
      corrects the time/date stamps to make the entries consistent, and
      writes to the standard output.  A - can be used in place of files to
      indicate the standard input.  If time/date corrections are not
      performed, acctcon1 will fault when it encounters certain date-change
      records.

      Each time the date is set, a pair of date change records is written to
      /etc/wtmp.  The first record is the old date denoted by the string old
      time placed in the line field and the flag OLD_TIME placed in the type
      field of the <utmp.h> structure.  The second record specifies the new
      date, and is denoted by the string new time placed in the line field
      and the flag NEW_TIME placed in the type field.  wtmpfix uses these
      records to synchronize all time stamps in the file.  wtmpfix nullifies
      date change records when writing to the standard output by setting the
      time field of the <utmp.h> structure in the old date change record
      equal to the time field in the new date change record.  This prevents
      wtmpfix and acctcon1 from factoring in a date change record pair more
      than once.

      In addition to correcting time/date stamps, wtmpfix checks the
      validity of the name field to ensure that it consists solely of
      alphanumeric characters or spaces.  If it encounters a name that is
      considered invalid, it changes the login name to INVALID and write a
      diagnostic to the standard error.  This minimizes the risk that
      acctcon1 will fail when processing connect accounting records.

 DIAGNOSTICS
      wtmpfix generates the following diagnostics messages:
