Hmm, which unix are you using. I came at this from a Linux perspective with GNU Date. If you don't have GNU date then some of those commands will def. fail. Also, as I said, it was off the top of my head, so the sed command regex will probably need some work.

Have to go eat with the inlaws now, so will look at this again tonight if you haven't solved it by then.

Things that might be pertinent:

what unix? (hpux, solaris, tru64 etc)
what version of unix?
do you have access to gnu date?
which shell? (bash, korn etc)

unix version :: SunOS 5.8

Shell type :: Korn

i am not sure of the GNU version of dates here .. i am a new to this platform

i am using sun solaris and Using ksh (Korn shell)

I'm quite new to perl but you can give this a try

Code:

perl -ane'BEGIN {
  @T = localtime(time+86400*30);
  $t = sprintf "%d-%02d-%02d", ($T[5]+1900),$T[4]+1,$T[3];
}
  chop $F[1]; $t lt $F[1] || print
' file

Of course, fixes and suggestions are welcome!

Thanks for the reply .. Can you also tell me , when there are no days in the range of 30 days .. it should print " no values are present

You can use something like this:

Code:

perl -ane'BEGIN {
  @T = localtime(time+86400*30);
  $t = sprintf "%d-%02d-%02d", ($T[5]+1900),$T[4]+1,$T[3];
}
chop $F[1]; 
if ($t gt $F[1]) { 
  $c++;
  print; 
}
print "No values present!\n" if (eof and !$c)
' file
