There was a problem hiding this comment.
From my end, same comments as in the other PR.
Add a Rust implementation of grcat, the helper binary shipped by GNU awk under lib/awk/. It dumps the group database in /etc/group format via POSIX getgrent()/endgrent(), matching the program described in the GNU Awk User's Guide and used by gawk library routines such as group.awk. - Register the grcat binary in Cargo.toml with a unix-only libc dependency - Handle BrokenPipe on stdout writes without exiting with an error - Add integration tests for output format and parity with getent group Closes uutils#60
