please help in multiple for loop
Hi
I have these data
0.9>i>0.1
0.45>j>0.01
I want to execute the script file for different number of i and j using the command
$ ./scriptfile i j
I write this code
#bin/bash
for ((i>0.1; i<0.9; i++))
for ((j>0.01; j<0.45; j++))
do
./scriptfile $i $j
done
However, for loop is not working with me. How can I fix the problem???
Regards

Code:
You can use seq here:

$ for i in $(seq .1 .1 .9); do for j in $(seq .01 .01 .45); do ./script $i $j; done; done

And in your script you missed one set of "do" and "done"; but I can't make this work

 for ((i=.1;i<.9;i=i+.1))
** not sure why

but 

for ((i=1;i<9;i=i+1))
works fine.

Thanks jaduks for the reply, but your code works only for the end values of i (i.e. i=.9) and j (i.e. j=.45) and I want to execute the file for all values of i and j which are in the range
0.9>i>0.1
0.45>j>0.01

shell scripts use integer arithmetic that's why i=i+0.1 wont work..i did the same mistake and had to use bc command instead..
