Hi, I'm using sort(1) version 8.13 in Ubuntu. It is case-insensitive, which I think is a bug. For example, it sorts the list "A b C d" as "A b C d", not as "A C b d". There is a -f option to fold lower case to upper for comparisons (i.e., to make sort case-insensitive, which seems to be the default anyway) but no option makes it case-sensitive, which is what I need.
Thanks, Bruce
