字符串处理，很神奇，第一次碰到。求高人

ligf@hot ~/tmp $ echo $a
/data/img/id(1).yuv
/data/img/id(2).yuv
/data/img/id(2).raw
/data/img/id(1).raw
/data/img/id
/data/img/id1
ligf@hot ~/tmp $ echo $a |while read IN;do echo 111${IN}222;done
222/data/img/id(1).yuv
222/data/img/id(2).yuv
222/data/img/id(2).raw
222/data/img/id(1).raw
222/data/img/id
222/data/img/id1
ligf@hot ~/tmp $ cat text.txt
/data/img/id(1).yuv
/data/img/id(2).yuv
/data/img/id(2).raw
/data/img/id(1).raw
/data/img/id
/data/img/id1
ligf@hot ~/tmp $ cat text.txt|while read IN;do echo 111${IN}222;done
111/data/img/id(1).yuv222
111/data/img/id(2).yuv222
111/data/img/id(2).raw222
111/data/img/id(1).raw222
111/data/img/id222
111/data/img/id1222
ligf@hot ~/tmp $


如上，请问，为什么两种对字符串的读取和输出会不一样呢。我如何把a变量里面的字符串，正常的按行输出

Shell_HAT

echo "$a" |while read IN;do echo 111${IN}222;done
