Add line number to for loop?

Code:

> cat test.sh
for t in `cat out.txt`
do
echo create directory data as "'"$t"';"
done
>

output of out.txt is as below

Code:

/oracle/SID/data1/file2_1/
/oracle/SID/data1/file1_1/
/oracle/SID/data1/file5_5/
/oracle/SID/data1/file_9/
/oracle/SID/data1/file_2/

when i run my test.sh script i get below output...

Code:

create directory data as '/oracle/SID/data1/file2_1/';
create directory data as '/oracle/SID/data1/file1_1/';
create directory data as '/oracle/SID/data1/file5_5/';
create directory data as '/oracle/SID/data1/file_9/';
create directory data as '/oracle/SID/data1/file_2/';

i want to modify my test.sh script to my output looks like below...note how the data changes to data_1, data_2 (basically line number, however many lines in out.txt)

Code:

create directory data_1 as '/oracle/SID/data1/file2_1/';
create directory data_2 as '/oracle/SID/data1/file1_1/';
create directory data_3 as '/oracle/SID/data1/file5_5/';
create directory data_4 as '/oracle/SID/data1/file_9/';
create directory data_5 as '/oracle/SID/data1/file_2/';

Variation on RudiC's suggestion with any POSIX compliant shell:

Code:

c=0
while read t
do
  printf "%s\n" "create directory data_$((c+=1)) as '$t';"
done < out.txt
