Users should avoid using the combination of -s with -z and -d '' in uutils coreutils cut until a fix is available or consult the vendor for updates.
Description
`cut` routes `-z -d ''` through a special newline-delimiter path that ignores the `-s` only-delimited flag, emitting whole undelimited records (plus NUL) that should be suppressed. Pipelines relying on `cut -s` to drop undelimited records process data that should be filtered. ``` printf 'abc' | cut -z -d '' -s -f 1 | od -An -tx1 # GNU: no output ; uutils: 61 62 63 00 ``` --- _Zellic private finding (zellic-ext/coreutils-private PR #102).
