I need to do this:

Code Sample

LIST=$LIST$ITEM[B]$LINEBREAK[/B]

I've tried even to use 'echo' to add line break but none has worked.
I've also searched Google already...

There are a few ways to do it, depending on how you want to use the variable.

One way is:

Code Sample

LIST=`echo -e "$LIST$ITEM\n"`

Another way is to use a different type of separator, such as a space or comma, when setting the variable, and then using tr to replace the separator with a newline when the variable is called.

You can try this, I just did and it works:

Code Sample

LIST="This and "
ITEM="That"
LINEBREAK="
"
TEST1=$LIST$ITEM[b]$LINEBREAK[/b]
TEST2="$LIST$ITEM[b]$LINEBREAK[/b]"

echo $TEST1
echo $TEST2

The second test succeeds because of the quotes, the first one fails by putting everything on one line. You need the quotes when you assign the variable.
