After some time spent experimenting with unix
sort I have noticed the following behaviour
betty ./adam ./cyril
The result of
sort files.list is the same as the result of
sort -d files.list:
./adam betty ./cyril
The manual page for
sort [OPTION]... [FILE]... -d, --dictionary-order consider only blanks and alphanumeric characters
But it seems that my
sort (GNU coreutils 8.17) behaves as if
-d were default. However, I have not found a way to turn it off.
So my question is, is there any difference when invoking sort with or without
-d? Is it possible to make sort not to ignore nonalphanumeric characters?
