Loading Multiple files using sqlldr in UNIX

Assumptions:
1) There has to be some way/standard to recognize the file name. In my case its a .dat file starting with sample. If you don't know data file name then create a directory specific to the load and select all data files from that directory.
2) The file format has to be same so that same .ctl file can be used to read the file and load the table.
3) Once loaded the file is then archived.

Control file code

LOAD DATA
insert into table sv_temp
fields terminated by '|' optionally enclosed by '"'
(first_col
,second_col
)

Shell Script Code

cd $CUSTOM_TOP/data
for file in sample*.dat
do
sqlldr userid=$login control=$CUSTOM_TOP/bin/sv_test.ctl data=$CUSTOM_TOP/data/$file
mv $CUSTOM_TOP/data/$file $CUSTOM_TOP/archive/$file
done

3 files sample1.dat, sample2.dat, sample3.dat was copied in CUSTOM_TOP/data directory.
Sample Output is
