This bug was previously reported in att/ast#37. Ksh ignores `-r` when `read -r -d` is run because when the bit for `D_FLAG` is set, the bit for `R_FLAG` is unset as a side effect of setting `D_FLAG`. The following set of commands fails to print a backslash: $ printf '\\\000' | read -r -d '' $ echo $REPLY The fix for this bug is to set `D_FLAG` with `D_FLAG + 1`, which prevents `R_FLAG` from being unset. This bugfix has been backported from ksh93v- 2013-10-10-alpha. src/cmd/ksh93/bltins/read.c: - Set `D_FLAG` with `D_FLAG + 1` to prevent the bit for `R_FLAG` from being unset. src/cmd/ksh93/tests/builtins.sh: - Add the regression test for `read -r -d` from ksh93v-. |
