info sort
A pair of lines is compared as follows: if any key fields have been
specified, `sort' compares each pair of fields, in the order specified
on the command line, according to the associated ordering options,
until a difference is found or no fields are left. Unless otherwise
specified, all comparisons use the character collating sequence
specified by the `LC_COLLATE' locale. |
