** Description changed: Impact Grepping null terminated records with -o option does not work. There may be a newline in a matched string, so the string may be ambiguous in output as matched parts are separated by newline. - Test Case $ printf 'a\0b\0b1' | grep --null-data b | hexdump -C 00000000 62 00 62 31 00 |b.b1.| 00000005 but $ printf 'a\0b\0b1' | grep -o --null-data b | hexdump -C 00000000 62 0a 62 0a |b.b.| 00000004 Expected result: 00000000 62 00 62 00 |b.b.| 00000004 + + Regression Potential + + Not remarkable. Scripts using -o -z are broken anyway with the broken + grep. + + This is fixed in Xenial, but IMO should be fixed in Trusty, too.
