Here is one perl script. Check for errors then have a try.
#!/usr/bin/perl
$PassMark = 40;
$InputFile = "filename";
$OutPutFile = "results";
open (INPUTFILE, "$InputFile") || die "Error Reason $!";
@DATA=<INPUTFILE>;
close(INPUTFILE);
open (RESULTFILE, ">$OutPutFile") || die "Error Reason $!";
foreach $Record(@DATA) {
chomp($Record);
my($Fname, $Sname, $Mark) = split(/ /, $Record);
if($Mark >= $PassMark) {
print RESULTFILE "$Fname $Sname PASS\n"; $s++;
} else {
print RESULTFILE "$Fname $Sname FAIL\n"; $f++;
}
}
close(RESULTFILE);
print "$f students Passed, $f Failed(don't hate them
)\n";
exit;
GoodLuck..!!

Good morning all!
I want to know if Im interpreting this if statement below right.
if(((1) || (0)) && (1)){
do stuff;
}
This is saying: if true piped into false, then true, then do stuff. Right?
What does the && stand for?
thanks in advance!

jifty::dbi::record::cachable
Jifty::DBI::Record::Cachable(3pm) User Contributed Perl Documentation Jifty::DBI::Record::Cachable(3pm) NAME
Jifty::DBI::Record::Cachable - records with caching behavior SYNOPSIS
package Myrecord; use base qw/Jifty::DBI::Record::Cachable/; DESCRIPTION
This module subclasses the main Jifty::DBI::Record package to add a caching layer. The public interface remains the same, except that records which have been loaded in the last few seconds may be reused by subsequent fetch or load methods without retrieving them from the database. METHODS
flush_cache This class method flushes the _global_ Jifty::DBI::Record::Cachable cache. All caches are immediately expired. _flush_key_cache Blow away this record type's key cache load_from_hash Overrides the implementation from Jifty::DBI::Record to add caching. load_by_cols Overrides the implementation from Jifty::DBI::Record to add caching. _cache_config You can override this method to change the duration of the caching from the default of 5 seconds. For example, to cache records for up to 30 seconds, add the following method to your class: sub _cache_config { { 'cache_for_sec' => 30 } } AUTHOR
