Now i want to write a script which need to take the first tablespace name from log 1 and then grep that tablespace in log 2 and search if any of the datafile is having less than 6000 mb then "echo .." And then take second tablespace name from log 1 and repeat the same...


Any help is appreciated..

Code:
grep -f datafile_test.log freedata_test.log| awk '$3 < 6000 {print $1}'

Assuming your 3rd column is in MB.

awk '{ if (FNR==NR) { a[$2]+=$3; next } if (a[$1] < 6000) { print $1 } }' freedata_test.log datafile_test.log

Use nawk or /usr/xpg4/bin/awk on Solaris.
I would do it all in sql though ...
Code:
awk 'NR == FNR { tbs[$1]; next }
$2 in tbs && $NF < 6000 {
  printf "tablespace %s, datafile %s has %d MB free\n",
    $2, $1, $NF
  }' datafile_test.log freedata_test.log

The OP said:

But, of course, your idea makes more sense.

perl:

Code:
@arr=('PSAPSR3','PSAPSR3700','PSAPSR3USR');
open FH,"<a.txt";
while(<FH>){
	@_= split(" ",$_);
	map {tr/\n//d} @_;
	$_{$_[1]}.=$_ if ($_[2]<6000);
}
close FH;
for($i=0;$i<=$#arr;$i++){
	print $_{$arr[$i]},"\n";
}
