Author: kevans Date: Fri Apr 13 17:57:00 2018 New Revision: 332482 URL: https://svnweb.freebsd.org/changeset/base/332482 Log: MFC r332372-r332374: tail(1)/head(1) compatibility long options r332372: tail(1): Add some long options Add --blocks, --bytes, and --lines long options for -b, -c, and -n respectively. This improves tail(1)'s compatibility with its GNU counterpart in a straightforward way. r332373: tail(1): Address mandoc concern (space before punctuation after macro) r332374: head(1): Provide long options Provide long options --bytes and --lines to match -c and -n respectively. This improves head(1)'s compatibility with its GNU counterpart in a sensible way.
