YESTERDAY(1)                                         YESTERDAY(1)

     NAME
          yesterday - print file names from the dump

     SYNOPSIS
          yesterday [ -cCd ] [ -n daysago ] [ -date ] files ...

     DESCRIPTION
          Yesterday prints the names of the files from the most recent
          dump.  Since dumps are done early in the morning,
          yesterday's files are really in today's dump.  For example,
          if today is February 11, 2003,

               yesterday /home/am3/rsc/.profile

          prints

               /dump/am/2003/0211/home/am3/rsc/.profile

          In fact, the implementation is to select the most recent
          dump in the current year, so the dump selected may not be
          from today.

          By default, yesterday prints the names of the dump files
          corresponding to the named files.  The first set of options
          changes this behavior.

          -c   Copy the dump files over the named files.

          -C   Copy the dump files over the named files only when they
               differ.

          -d   Run diff to compare the dump files with the named
               files.

          The date option selects other day's dumps, with a format of
          1, 2, 4, 6, or 8 digits of the form d, dd, mmdd, yymmdd, or
          yyyymmdd.

          The -n option selects the dump daysago prior to the current
          day.

          Yesterday does not guarantee that the string it prints rep-
          resents an existing file.
