exp/imp Korn Shell scripts

Today, I am releasing two scripts that will allow the people here to export a schema and re-import it into another database. Both are Korn Shell scripts so obviously they are for Unix or variants.
=======================================================================
export.sh -
Usage: export.sh -p [dba_user_password] -d [tns_entry_of_db_2_exp] -f [export_file_name.dmp] -s [schema_nameschema_name,shema_name<,...>]

These parameters need to be in the order as shown. The -s option can either be a space or comma (no spaces) list.
========================================================================
import.sh -
Usage: import.sh -p [dba_user_password] -d [tns_entry_of_db_2_exp] -f [export_file_name.dmp]
========================================================================

In both scripts the -f option can have the full path to another directory, but will automatically change the path to the predefined variable using the filename supplied.

In both scripts if any option is omitted, the user will be prompted for the value.

Here are the scripts!:
