Shell Programming and Scripting

Hello all, I have a bash function that opens Safari (I'm on OS X) with a specified argument.

Here it is :

Code:

function safari
{

#Safari bash function

TLDS=( "http://www."  ".com"  ".org"  ".net"  ".gov"  ".edu" )

if [ $1 = "-o" ]; then
open -a Safari ${TLDS[0]}$2${TLDS[2]} 
	elif [ $1 = "-n" ]; then
	open -a Safari ${TLDS[0]}$2${TLDS[3]}
		elif [ $1 = "-g" ]; then
		open -a Safari ${TLDS[0]}$2${TLDS[4]}
			elif [ $1 = "-e" ]; then
			open -a Safari ${TLDS[0]}$2${TLDS[5]}
				elif [ $1 = "-c" ]; then
				open -a Safari ${TLDS[0]}$2${TLDS[1]}
					else
					open -a Safari ${TLDS[0]}$1${TLDS[1]}
fi

}

I don't have a problem with the function, but I would like to know if my function can have a command history, like after each argument is taken, is it possible that i could write it to a file for later retrieval?

for example after a ( this is my prompt ) :

(%) ~ <-- safari arstechnica // opens Safari @ arstechnica.com

(%) ~ <-- safari ars[TAB] // completes as arstechnica after reading file
