Connect to Oracle database through Unix

Due to my professional requirements nowadays I use Oracle most of the time and sometimes I need to use Oracle through Linux environment. Today I am going to discuss the basics of connecting to Oracle database through Linux. For this purpose Oracle provided us a pretty cool utility with a basic command line interface.

Use Indent to indent your C-code

I myself not very much expert in writing indented code and code without indentation looks just horrible. Of course you will not have same feelings if you are using an IDE with auto indentation facility and of course if you know how to write indented code. For this purpose I found Indent command very useful in linux. One thing you should remember that this command is only for C code.
Actually not me, one of my friend Arjun Pakrashi informed me about this command.
