Thanks that could be a solution.

Note that I don't have the issue with cat.
bash-3.2$ cat test1 > test2
bash-3.2$ xxd test2
0000000: 6161 610d 0a62 6262 0d0a                 aaa..bbb..

I don't have it with sort used alone :
bash-3.2$ /usr/bin/sort test1 > test2
bash-3.2$ xxd test2
0000000: 6161 610d 0a62 6262 0d0a                 aaa..bbb..

But get it when using sort in a pipe with cat :
bash-3.2$ cat test1 | /usr/bin/sort > test2
bash-3.2$ xxd test2
0000000: 6161 610d 0d0a 6262 620d 0d0a            aaa...bbb...

But using more instead of cat solves the issue :
bash-3.2$ more test1 | /usr/bin/sort > test2
bash-3.2$ xxd test2
0000000: 6161 610d 0a62 6262 0d0a                 aaa..bbb..
