Regarding sort: `-f' `--ignore-case' Fold lowercase characters into the equivalent uppercase characters when comparing so that, for example, `b' and `B' sort as equal. The `LC_CTYPE' locale determines character types.
OK, but also document this: $ echo -e 'A\na'|sort -uf A $ echo -e 'A\na'|sort -ufr A $ echo -e 'A\na'|sort -urf A The man page doesn't say what to expect. _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
