Auto execute unix scrips

Hello Friends,
Till date,I didnt get any opportunity to learn about how to write a shell script.But now my work is hectic and the nature of work is to execute a series of OS commands and to run shell scripts in unix environment.

could some one please help me with a script in which i can add all other scripts .Only after 1 script gets over(as command prompt again appears),the next script or command should get executed. could some one help here?
