From 7152645618fc22766f5c954d12e9489866633e26 Mon Sep 17 00:00:00 2001 From: Jody Frankowski Date: Thu, 31 Oct 2024 13:13:20 +0100 Subject: color: Handle bfs_check_capabilities error code (-1) in cpath_has_capabilities On non-Linux systems, bfs_check_capabilities always returned -1, so cpath_has_capabilities would always return true. If bfs was called with an LS_COLORS containing the `ca` statement, e.g. `ca=30;41`, bfs would color ALL the files. While including the `ca` statement in LS_COLORS on non-Linux systems is unusual, this is not an error and is a valid use-case (e.g. Using GNU ls or lsd).
