Reading line from file which holds braces and comma

in ksh I have a input file that holds the following:

$ cat input.txt
A {111 222 111}
B {333,444,333}
C {555 666 555}
$

When I Run the following command Im getting the following

$ while read LINE
> do 
>   echo $LINE
> done<input.txt
A {111 222 111}
B 333 444 333
C {555 666 555}
$


How to insure to read lines as is with braces and comma?

>Solution :

In order to avoid special syntax with braces and coma in ksh when you are doing an echo, add quotation marks around $LINE:

while read LINE
do 
    echo "$LINE"
done<input.txt

The syntax {1,2,3...} is useful for loops:

for x in {1,a,3}; do echo x=$x; done
x=1
x=a
x=3
