- installation scripts for various OS packages (RPM, Deb, Apk) for various Linux distros ([Redhat RHEL](https://www.redhat.com/en/technologies/linux-platforms/enterprise-linux) / [CentOS](https://www.centos.org/) / [Fedora](https://getfedora.org/), [Debian](https://www.debian.org/) / [Ubuntu](https://ubuntu.com/), [Alpine](https://alpinelinux.org/))
- install if absent scripts for Python and Perl modules - good for combining with first attempt to install via system packages, and then these will pull from [PyPI](https://pypi.org/) or [CPAN](https://www.cpan.org/) only those modules which aren't installed. This speeds up builds and uses the standard packaged modules where possible. This is also more reliable than getting random compile errors from CPAN as libraries update and introduce bugs or needing to install too many dev libraries
- install scripts for [Jython](https://www.jython.org/) and build tools like [Gradle](https://gradle.org/) and [SBT](https://www.scala-sbt.org/) for when Linux distros don't provide packaged versions or where the packaged versions are too old
- ongoing work-in-progress as I still have thousands of lines of code from the last ~15 years to sanitize and export here (I typically have around 1000 aliases and 500 functions in total, plus some magic prompt hook custom shell behaviours and several hundred external scripts - a few hundred of which can now be found across [my other github repos](https://github.com/HariSekhon))
-`lib/*.sh` - Bash utility libraries full of functions for [Docker](https://www.docker.com/), environment, CI detection ([Travis CI](https://travis-ci.org/), [Jenkins](https://jenkins.io/)), port and HTTP url availability content checks etc.
-`kafka_wrappers/*.sh` - scripts to make [Kafka](http://kafka.apache.org/) cli usage easier including auto-setting Kerberos to source TGT from environment and auto-populating broker and zookeeper addresses. These are auto-added to the `$PATH` when `.bashrc` is sourced. For something similar for [Solr](https://lucene.apache.org/solr/), see `solr_cli.pl` in [DevOps Perl Tools](https://github.com/harisekhon/devops-perl-tools)
* [Advanced Nagios Plugins Collection](https://github.com/harisekhon/nagios-plugins) - 450+ programs covering every major Hadoop & NoSQL technology and Linux/Unix based infrastructure technologies
[Pre-built Docker images](https://hub.docker.com/u/harisekhon/) are available for those repos (which include this one as a submodule) and the ["docker available"](https://hub.docker.com/r/harisekhon/centos-github/) icon above links to an [uber image](https://hub.docker.com/r/harisekhon/centos-github/) which contains all my github repos pre-built. There are [Centos](https://hub.docker.com/r/harisekhon/centos-github/), [Debian](https://hub.docker.com/r/harisekhon/debian-github/) and [Ubuntu](https://hub.docker.com/r/harisekhon/ubuntu-github/) versions of this uber Docker image containing all repos.
