Hi,
I will guide you but i am not give you complete solution.
first try yourself if you receive any error and concern with us.

Cold Backup Script.
1.Shutdown immediate + normal ( database your database)
2.copy all *.ctl , *.dbf, *.log or spfile and password.
3.startup ( startup your database for normal operation).

for above you have to create .sh ( shell script)
through chmod grant read , write and execute permission to OS user.
Schedule ".sh" script through CRONTAB utility.

-----------------------------------------------------
Hot backup through USER MANAGED BACKUP.
alter tablespace begin backup ....COPY......end backup.
backup your *.arc log files.
For Control file.
alter database backup control file to trace;
or
alter database backup control file to 'OS PATH';
for above some create ".sh" file and grant permission.
---------------------------------------------------------
Hot backup through RMAN tool.

----------------------------------------------------------

Go through below link http://dbataj.blogspot.com/search/label/Backup%20Scripts

above script based on WINDOWS but for overview you can take a look.
