Index: bin/awk 4.2BSD [Fix] Description: Awk doesn't allow you to replace fields. This bug was introduced when the indirect-through-zero bugs in awk were fixed. Repeat-By: The following command echo 1 2 3 | awk '{$1 = NF; print}' should give 3 2 3 if it works. If it's broken it will give 1 2 3 Fix: Install the following fix: --- awk.def 7a8 > #define isnull(x) ((x) == EMPTY || (x) == NULL) --- tran.c 139c139 < if ((vp->tval & FLD) && vp->nval == 0) --- > if ((vp->tval & FLD) && isnull(vp->nval)) 154c154 < if ((vp->tval & FLD) && vp->nval == 0) --- > if ((vp->tval & FLD) && isnull(vp->nval))
