Reading a string and passing passing arguments to a while loop
I have an for loop that reads the following file

Code:
cat param.cfg
val1:env1:opt1
val2:env2:opt2
val3:env3:opt3
val4:env4:opt4
.
.

The for loop extracts the each line of the file so that at any one point, the value of i is
Code:
val1:env1:opt1

etc...

I would like to extract each individual attribute and pass it to a while loop as follows:

Code:
for i in $( cat refire.cfg | tail +$START | head -$STOP | grep -v "^#" | grep ':' )
do
# read the value of i here and break it down as arguments x y z for this loop
while read x y z 
do
stuff
done
done

Quote:
The variables $START & $STOP determines the range of execution of the param.cfg file
I want to be able to repeat the while loop for each iteration of i
