Calling a UNIX shell script from PL/SQL procedure?

In a pl/sql script, I want to call a shell script that kicks off sqlldr and loads a data file. I was told that I could issue the command
!nameofshellscript inside the procedure and this would call the script. However, the pl/sql compiler does not like the '!' symbol. How should this be done, or can it be done?
