Change Details

Lift the restriction in uniq(1) that -c cannot be used with the -d and -u options. This restriction seems unnecessary and is supported at least by GNU, OpenBSD, and NetBSD. Lift the restriction and simplify the show() logic a little bit to maintain functionality when -c is provided with -d/-u. Adjust the man page and usage() to reflect that -c is its own standalone option. -d and -u will be left alone for the time being, although the documentation here is a bit misleading since -d and -u are actually not mutually exclusive and represent the default behavior of uniq(1). This is a partial revert of r98547. PR: 200553

Bring in some bits from NetBSD and lift the restriction in uniq(1) that -c cannot be used with the -d and -u options. This restriction seems unnecessary and is supported at least by GNU, OpenBSD, and NetBSD. Lift the restriction and simplify the show() logic a little bit to maintain functionality when -c is provided with -d/-u. Also with this change, -d and -u are now actually a mutually exclusive, albeit valid, combination. Given that they both indicate opposite behavior, `uniq(1)` will no longer output anything if both -d and -u are supplied. This is in line with NetBSD as well as GNU, and likely OpenBSD but this has not been checked. Adjust the man page and usage() to reflect that -c is its own standalone option.
