Doesn't work for me.  What am I doing wrong?

$ sh test
/tmp/mydir1_apo
_apo: 2: cd: can't cd to mydir2
/tmp/mydir3_apo

$ cat test
while IFS=$' \t\r\n' read -r d; do
  ( cd ${d}_apo || exit
    pwd
  )
done < /tmp/input

$ od -c input
0000000   m   y   d   i   r   1  \n   m   y   d   i   r   2  \r  \n   m
0000020   y   d   i   r   3  \n
0000026
