From 92e14524d48348e4ba748e3c1e2d25f8c5f4ebee Mon Sep 17 00:00:00 2001 From: Kerin Millar Date: Sun, 25 Jun 2023 21:03:04 +0100 Subject: [PATCH] bin/save-ebuild-env.sh: refrain from using the compgen builtin For the compgen builtin to be available requires that bash be compiled with --enable-readline. Rather than rely on compgen to generate a list of function names, parse their names out of declare -F instead. Specify -v for the following unset command, so that bash is coerced into unsetting only variables, as is intended. Expand the applicable variable names with "${!___@}". Owing to the constraints placed on identifiers, it's not particularly important that it be done this way, but I think it better expresses the intent.
