* | sed: drop \r when reading inputRon Yorston2016-03-161-0/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An upstream bug (https://bugs.busybox.net/show_bug.cgi?id=8791) reports: $ cat myfile a b c $ sed "s/\(.*\)/\1\1/" myfile a b c it should be: $ sed "s/\(.*\)/\1\1/" myfile aa bb cc This happened because busybox-w32 opens files in binary mode. Lines read by sed had trailing LFs removed but not trailing CRs. The CRs ended up in the matched strings and were output, thus giving the appearance that only one of the backreferences was printed. The same happens on Linux when a DOS file is processed by BusyBox sed or GNU sed. However, this behaviour is arguably incorrect on Windows. I've modified busybox-w32 to drop trailing CRs as well as LFs from input lines.
