Is that ok? Please don't. Not every grep(1) has PCRE support so it would be great if you could rephrase it to use just use normal regexp or ERE. like e.g.: grep -q -E "^ARC_CPU \(hs38,[ ]*[emhs]+," config/arc/arc-cpus.def where the space is <space><^vi>, i.e. space, tab Or use an awk script that exits appropriately if the arg matches ARCH. TIA,
