I'm looking for an way to use Arduino Uno + GSM Shield as normal GSM modem where it can take direct AT command from computer and process instead of writing in sketch.
Where should I start with this?
Any help is appreciated!
You could either write a sketch that just bridges the GSM modem's SoftwareSerial interface with the USB Serial interface, or use the UNO's USB interface as an adapter and connect pins 0,1 and 2,3 directly to each other (with a sketch that configures them all as inputs) so that the USB serial interface and the modem talked directly to each other.

Do you have a link to an specific example I can take a look?

The example shown in the reference documentation for SoftwareSerial is essentially bridging a SoftwareSerial port with the hardware Serial port.
