Look at the PATH statement and put it in the path directory ahead of the others, typically put your version into /usr/local/bin , which is generally in the search $PATH s
(echo $PATH) /usr/local/bin:/usr/local/sbin:/usr/bin:/bin/usr/sbin Regards Leslie On Thursday, July 2, 2020, 1:19:19 a.m. EDT, Jeffrey Walton <noloa...@gmail.com> wrote: Hi Everyone, The BLAKE2 folks have optimized implementations for b2sum on i686, x86_64, NEON and PowerPC. It also has more options than the coreutils version. I'd like to disable b2sum in coreutils and use the BLAKE2 team's version. Is it possible to disable b2sum from coreutils? If so, how? Thanks in advance.
