It seems the gnu sort utility does destructive sort?

i.e. if my file is:

b y
b x

and i do “sort -k 1 myFile� then the line got re-ordered?

is there a way to use sort so that if the field is a tie, it leave the
original order as is?

Thanks

Got the answer to my own question from help on freenode irc. To do non-
destructive sort with gnu sort, use -s.
