Trying to write some code that will sort a bunch of log entries by date. It will run like this:
cat crap | mysort > sorted_crap
Since there are many log entries per second, the plan is to push each
entry on to an array keyed by the unix time, then print each entry for
(sort %bighash). Here's what I have:
$log_entries = {};
while ( <STDIN> ) {
# Date string looky like: "06/Apr/2001:08:30:05"
/(\d{2}\/\w{3}\/\d{4}\:\d{2}\:\d{2}\:\d{2})/;
$secs = parsedate($&);
push @{$log_entries->{$secs}}, $_;
}
foreach $key (sort %$log_entries) {
foreach $entry (@{$log_entries->{$key}}) {
print $entry;
}
}
This all goes to hell when the size of
crap gets real big, ie,
Out of memory!. Can anyone suggest a more efficient solution?
