Howdy Do That ? HYDT | A series of Handy How To Dos.

Howdy Do that? (How Do you do that?) (HYDT)
Starting today, I intend on blog publishing tech anecdotes, handy snippets, how to do stuff on practically anything that I have garnered over years of IT experience. Often, it happens, that you have solved a murky lurky problem/ task in one situation only to face the same with or without some twist later on (maybe after quite some time) . So while many of us remember, and reconstruct the steps, a how to do snippet does come in handy in resolving the issue quickly and also serving as a guide to anyone else who faces the same task/ problem.
What will go in HYDT ?
Practically anything from any topic under the sun like:

• How do I truncate a file to zero bytes in Unix/ Linux ? (Useful in truncating logs)
  
• How do I take a command line DB Dump export in Oracle and import into another schema ?

and lots of other stuff like that. All such posts will be marked as : HYDT | Post Subject Here
Be tuned !
