Thank you for the answers.

It seemed that I had \r\n at the end of the line and I replaced it with \n but the outputs are still the same.
This is what I get when I write
Code:
head file | od -bc

(the lines are actually longer so this is adapted to my sample file)

Code:
0000000 147 156 141 141 143 137 144 141 147 137 163 165 142 155 151 164
          a   b   c   _   b   l   a   _   s   u   b   m   i   t
0000020 040 055 147 167 145 145 153 040 070 060 062 040 012 147 156 141
              -   d   e   f       8   0   0      \n   a   b   c
0000040 141 143 137 144 141 147 137 163 165 142 155 151 164 040 055 147
          _   b   l   a  etc.
