How to loop around the contents of file?

Hi ,
I need to print the contents of a file in a loop
I tried like below but didn't get the contents in the output
The file nms.txt has some names like
apple
grapes
---
Code:
#!/bin/ksh
file_nm="/etc/nms.txt"
for data in "echo {$file_nm}"
 do
  echo "$data"
done

The above code gives me the output as
Code:
echo {/etc/nms.txt}

I want the output in the echo as
apple
grapes
----

Please suggest me

change the for code as follows :-
Code:
for data in `echo {$file_nm}`  do   echo "$data" done

Use while loop instead of for lop..

Code:
file_nm="/etc/nms.txt"
while read data
do
echo $data
done<$file_nm
