I have a file with a bunch of lines. Each one of these lines has 8 semi-colon delimited columns.
How can I (in Linux) return duplicate lines but only based on column number 2? Should I be using grep or something else?

Count of the fields in second column count[$2]++; # Save the line the first time we encounter a unique - data.txt
The beauty of this solution is it preserve the line order at the expense of using many tools.

Not only that,....
Which works great best to be pragmatic and only enforce an 80 column limit if it makes sense to do so...ie the 80 column limit irrelevant.
We have a 100 column standard.
It completely depends on the monitor you use.

The beauty of ORM lulled me into a soporific sleep.
I was thinking maybe some middleware that logs which columns are involved in WHERE clauses? but is there anything built into MySQL that might help?

Indexes are a balancing act between fast....
Adding indexes willy-nilly to all "slow" queries will also slow down inserts, updates and deletes .
If you take a look at the slow query log , there's an option --log-queries-not-using-indexes
No .
Yes, there is.

In my code I can reference the Column using it's index. But I'd much rather use it's name. Is this possible? I have no idea. :D

Hey guys,
I've been working on a set of layerable moles and all has gone well until I get them in CAS.
The game recognizes my new moles...but...it doesn't have room to display them all. Like it only shows the first row...

The Durutti Column I must admit that I am feeling 'that way out' lately, passing the torch as it were.

I liked the idea of aliasing the column names and using that as the table headers, but it would have the order of the data (ascending, descending):
