arch
It's very common in build scripts to have to generate, for example, paths that describe a platform, a build environment, a yum repo path, etc. Usually, I'd use uname -p to get the processor type, but arch is faster to type and self-documenting. //nsupdate <<EOF update add
arpaname $ipaddr
86400 IN PTR $(hostname -f).
send
EOF
This would be easy enough to use inside a loop for when I might have a bunch of new IoT devices, VMs, or a fleet of laptops to install and already have their hostnames/IPs in a simple CSV file or otherwise generated them.
