From re_format(7): A branch is one=E2=80=A1 or more pieces, concatenated. A piece is an atom possibly followed by a single=E2=80=A1 =E2=80=98*=E2= =80=99, =E2=80=98+=E2=80=99, =E2=80=98?=E2=80=99, or bound. An atom is ... , or a single character ... Consider: % echo foobar | awk -F o -v OFS=3DX '{$1=3D$1;print}' fXXbar % echo foobar | awk -F oo -v OFS=3DX '{$1=3D$1;print}' fXbar % I don't think there is a need to separately reference single-character lite= ral REs. (And unless I'm missing something I think the gawk man page is misguided for doing so.) --=20 You are receiving this mail because: You are the assignee for the bug.=
