78 5691dc7b 2023-05-05 benni The
79 5691dc7b 2023-05-05 benni .B lsblk(8)
80 5691dc7b 2023-05-05 benni utility was originally written by the
81 5691dc7b 2023-05-05 benni .B util-linux
82 5691dc7b 2023-05-05 benni project.
83 5691dc7b 2023-05-05 benni This is an
84 5691dc7b 2023-05-05 benni .I incompatible
85 5691dc7b 2023-05-05 benni clone of the original \fBlsblk\fR.
86 5691dc7b 2023-05-05 benni It is incompatible because it doesn't support
87 5691dc7b 2023-05-05 benni the same set of options as the original
88 5691dc7b 2023-05-05 benni and because of differences in the output.
89 5691dc7b 2023-05-05 benni More incompatibilities are caused by specific features only being available
90 5691dc7b 2023-05-05 benni on either Linux or OpenBSD.
