Bug Nested for loop not ending

Hi All,

Need help on below script

Code:
for g in `cat /home/sid.txt`
do
for h in `cat /home/dev.txt`
do
symmaskdb -sid $g -dev $h list assign |grep FA |head -1|awk '{print $2}' > tt1.txt
done
done

cat /home/sid.txt
**************
Code:
123
235
456

cat /home/dev.txt
***************
Code:
35
67
88

I sould get the loop to run like below

Code:
symmaskdb -sid 123 -dev 35 list assign |grep FA |head -1|awk '{print $2}' 
symmaskdb -sid 235 -dev 67 list assign |grep FA |head -1|awk '{print $2}' 

symmaskdb -sid 456 -dev 88 list assign |grep FA |head -1|awk '{print $2}' 

But current the lopp is running like this

Code:
symmaskdb -sid 123 -dev 35 list assign |grep FA |head -1|awk '{print $2}' 
symmaskdb -sid 123 -dev 67 list assign |grep FA |head -1|awk '{print $2}'
