String variables in shell script

[SlowMove]

Does anyone know how to assign each line of a text file to a string variable in a bash script?
I tried the following:

for x in $(cat ./filename)
do
 echo $x
done

What happened is that it assigned each word instead of each line in the file to the variable.

I think it's a limitation of for... Try "read" instead

cat filename ¦ while read A; echo $A; done

Another way ...

while read A
echo $A
done < filename

You can also do this:

cat filename ¦ while read line; do $line; done
