A curated list of command-line utilities written in Rust

Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.

Configure Raspberry Pi Networking

It is possible to run 3 consul servers on the same IP address if you shift the various ports to unique numbers to avoid conflict, but you don't have to do that.

Instead, add interface alias's in your /etc/rc.local (just before the exit 0), e.g.:

In my case, wlan0 is a dhcp assigned interface. The following commands add three new alias interfaces, wlan0:1, etc, with their own stat IP Addresses.

ifconfig wlan0:1 inet 10.0.0.41 netmask 255.255.255.0
