As followup to our retrospective, this past year I've found and played with several tools, that I thought might be worth show-and-telling about, and given our corona-sprint we're in will do so via email:
== so-trello == This CLI allows programmatic interaction with Trello boards. It was written by our own Kernel team's Andy Whitcroft. This looks like it could be handy for bulk operations, cronned/automated card update tasks, and the like. So-trello can be downloaded from the snap store (https://snapcraft.io/so-trello), or installed directly: $ sudo snap install so-trello == LXD Login == I'm always looking for ways to improve my user experience with lxc containers. Logging in has always felt a bit baroque, so I've been scouring for simpler solutions. I found out that LXD supports 'aliases', and that you can construct a login alias, which works pretty good. $ lxc alias add login 'exec @ARGS@ --mode interactive -- bash -xac $@bryce - exec /bin/login -p -f ' (The trailing space after the -f is important). Replace 'bryce' with 'ubuntu' or whatever username you use in your containers. Unfortunately, it still requires running `script /dev/null` after logging in... would love to figure out how to eliminate that step. Bonus, here's an alias to make a prettier lxc listing: $ lxc alias add ls 'list -c ns4,user.comment:comment' If I'm late to the party and y'all already know about lxd aliases, well boo, but show me *your* aliases! (And we should add this to starter docs...) == YAML Parser for Bash scripts - yaml.sh == I like YAML and I like writing in Bash, but the two don't fit together naturally. Scouring the web for solutions, I found AdrianDC's yaml.sh which reads a YAML file and registers its parameters as prefixed ENV vars. Quite handy. yaml.sh can be downloaded from: $ wget https://raw.githubusercontent.com/jasperes/bash-yaml/master/script/yaml.sh == shellcheck == Probably known to all Bash aficionados already, but 'shellcheck' is so handy worth extra mention. It runs a lint check on bash scripts to identify syntax improvements. Very helpful for catching errors too. $ sudo apt-get install shellcheck == distro-info == Another one I'm sure you all already know about, but if not, distro-info is another handy tool for looking up information about Debian and Ubuntu releases. Good way to avoid hardcoding things in your own scripts. $ sudo apt-get install distro-info What's the current development version's codename? $ distro-info -d focal What's bionic's release number? $ distro-info --release --series bionic | cut -d' ' -f1 18.04 Is disco still supported? $ (distro-info --supported | grep disco) || echo "Nope!" Nope! -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
