Here is a PERL way. It's not simple but it's fast.

Code:
#!/usr/bin/perl

open(F,"/tmp/input") || die "Can't open /tmp/input $!\n";
while(<F>){
    ($COL1,$COL2,$COL3,$COL4,$COL5,$COL6,$COL7,$COL8,$COL9,$COL10)   = split(/,/);
if ( $COL6 == "52" ) {
    print "$COL6\n";
} else {
    print "52 not found\n";
       }
}
