Code:
#!/usr/bin/ksh

export FROM_DATE=04/05/2008
export TO_DATE=02/06/2008
export F=$(echo $FROM_DATE|awk -F"/" '{print $3$2$1}')
export T=$(echo $TO_DATE|awk -F"/" '{print $3$2$1}')
perl -ne '$l=$_;($d,$m,$y)=(split(/\//, (split(/-/, $l))[0] ))[0..2]; $dt="$y$m$d";
print $l if ($dt >= "'$F'" && $dt <= "'$T'" )' monitor.audit

You might as well do that too in Perl.

Code:
perl -ne '$l=$_;($d,$m,$y)=(split("/", (split(/-/, $l))[0] ))[0..2]; $dt="$y$m$d";
  $f = join ("",(split ("/", $ENV{"FROM_DATE"}))[2,1,0]);
  $t = join ("", (split ("/", $ENV{"TO_DATE"}))[2,1,0]);
  print $l if ($dt >= $f && $dt <= $t )' monitor.audit

If the dates are mm/dd/yyyy ones, you can replace [2,1,0] with [2,0,1] (in both places, of course).

Even better, use yyyymmdd format for FROM_DATE and TO_DATE to begin with.
