150+ Shell Scripts, Advanced Bash environment & Utility Code Library used by all my other [GitHub](https://github.com/harisekhon) repos 200+ [CI builds](https://github.com/HariSekhon/DevOps-Bash-tools/blob/master/STATUS.md).
- advanced `.bashrc` + `.bash.d/*.sh` - tonnes of advanced customizations and functions like `pass` which prompts for a password (star echo'd to screen) and stores it in the shell environment ram, which several scripts can then use to curl APIs without re-entering the password each time, nor exposing passwords on the CLI or in audit logs from command logging
- advanced configuration files for common tools like [vim](https://www.vim.org/), [screen](https://www.gnu.org/software/screen/), [tmux](https://github.com/tmux/tmux/wiki), installs the best sysadmin packages like those above plus [AWS CLI](https://aws.amazon.com/cli/), [GCloud SDK](https://cloud.google.com/sdk), [jq](https://stedolan.github.io/jq/) and many others, adds dynamic Git and shell behaviour enhancements, colouring, functions, aliases and automatic pathing of many common installation locations for many major languages like Python, Perl, Ruby, NodeJS, Golang...
- Adds sourcing to `.bashrc`/`.bash_profile` to automatically inherit all `.bash.d/*.sh` environment enhancements for all technologies (see [Inventory Overview](https://github.com/harisekhon/devops-bash-tools#Inventory-Overview) below)
- Symlinks all `.*` config files to `$HOME` for [git](https://git-scm.com/), [vim](https://www.vim.org/), top, [htop](https://hisham.hm/htop/), [screen](https://www.gnu.org/software/screen/), [tmux](https://github.com/tmux/tmux/wiki), [editorconfig](https://editorconfig.org/), [Ansible](https://www.ansible.com/) etc.
`make install` effectively does `make system-packages bash python aws`, but if you want to pick and choose from different sections, see [Individual Setup Parts](https://github.com/harisekhon/devops-bash-tools#Individual-Setup-Parts) below.
- 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, Perl, Ruby, NodeJS and Golang packages - good for minimizing the number of source code installs by first running the OS install scripts and then only building modules which aren't already detected as installed (provided by system packages), speeding up builds and reducing the likelihood of compile failures
- 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
-`.*` - dot conf files for lots of common software eg. advanced `.vimrc`, `.gitconfig`, massive `.gitignore`, `.editorconfig`, `.screenrc`, `.tmux.conf` etc.
-`.vimrc` - contains many awesome [vim](https://www.vim.org/) tweaks, plus hotkeys for linting lots of different file types in place, including Python, Perl, Bash / Shell, Dockerfiles, JSON, YAML, XML, CSV, INI / Properties files, LDAP LDIF etc without leaving the editor!
-`.screenrc` - fancy [screen](https://www.gnu.org/software/screen/) configuration including advanced colour bar, large history, hotkey reloading, auto-blanking etc.
-`.tmux.conf` - fancy [tmux](https://github.com/tmux/tmux/wiki) configuration include advanced colour bar and plugins, settings, hotkey reloading etc.
- automatic GPG and SSH agent handling for handling encrypted private keys without re-entering passwords, and lazy evaluation to only prompt key load the first time SSH is called
- run `make bash` to link `.bashrc`/`.bash_profile` and the `.*` dot config files to your `$HOME` directory to auto-inherit everything
-`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. Sourced from all my other [GitHub repos](https://github.com/harisekhon) to make setting up Dockerized tests easier.
-`setup/install_*.sh` - various simple to use installation scripts for common technologies like [Ansible](https://www.ansible.com/), [Terraform](https://www.terraform.io/), [MiniKube](https://kubernetes.io/docs/setup/learning-environment/minikube/) and [MiniShift](https://www.okd.io/minishift/) (Kubernetes / [Redhat OpenShift](https://www.openshift.com/)/[OKD](https://www.okd.io/) dev VMs), [Maven](https://maven.apache.org/), [Gradle](https://gradle.org/), [SBT](https://www.scala-sbt.org/), [EPEL](https://fedoraproject.org/wiki/EPEL), [RPMforge](http://repoforge.org/), [Homebrew](https://brew.sh/), [Travis CI](https://travis-ci.org/), [Parquet Tools](https://github.com/apache/parquet-mr/tree/master/parquet-tools) etc.
-`aws*.sh` - various [AWS](https://aws.amazon.com/) scripts for EC2 metadata, Spot Termination, SSM Parameter Store secret put from prompt, IAM Credential Reports on IAM users without MFA, old access keys and passwords, old user accounts that haven't logged in or used an access key recently, show password policy / set hardened password policy, show unattached IAM policies, show account summary to check various details including root account MFA enabled and no access keys, KMS keys rotation status, CloudTrail & Config status etc.
-`curl_auth.sh` - wraps curl to send your username and password from environment variables or interactive prompt through a ram file descriptor to avoid using the `-u`/`--user` which might otherwise expose your credentials in the process list or OS audit log files. Used by other API querying scripts
-`k8s_api.sh` - finds Kubernetes API and runs your curl arguments against it, auto-getting authorization token and populating `Authorization: Bearer` header
-`ldap_user_recurse.sh` / `ldap_group_recurse.sh` - recurse Active Directory LDAP users upwards to find all parent groups, or groups downwards to find all nested users (useful for debugging LDAP integration and group-based permissions)

Built on top of `cloudera_navigator_api.sh`
-`beeline.sh` - connects to [HiveServer2](https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Overview) via beeline, auto-populating Kerberos and SSL settings, zookeepers for HiveServer2 HA discovery if the environment variable `$HIVE_HA` is set or using the `$HIVESERVER_HOST` environment variable so you can connect with no arguments (prompts for HiveServer2 address if you haven't set `$HIVESERVER_HOST` or `$HIVE_HA`)
-`beeline_zk.sh` - connects to [HiveServer2](https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Overview) HA via beeline, auto-populating SSL and ZooKeeper service discovery settings (specify `$HIVE_ZOOKEEPERS` environment variable to override). Automatically called by `beeline.sh` if either `$HIVE_ZOOKEEPERS` or `$HIVE_HA` is set (the latter parses `hive-site.xml` for the ZooKeeper addresses)
-`hive_foreach_table.sh` - executes a SQL query against every table, replacing `{db}` and `{table}` in each iteration eg. `select count(*) from {table}`
-`hive_*.sh` - various scripts using `beeline.sh` to list databases, tables, for all tables: row counts, DDL metadata field extraction, table locations etc.
-`impala_shell.sh` - connects to [Impala](https://impala.apache.org/) via impala-shell, parsing the Hadoop topology map and selecting a random datanode to connect to its Impalad. This is mostly for convenience to shorten commands and while it acts as a poor man's load balancer, you might want to instead use my real load balancer [HAProxy config for Impala](https://github.com/HariSekhon/HAProxy-configs) (and many other Big Data & NoSQL technologies). Optional environment variables `$IMPALA_HOST` (eg. point to HAProxy load balancer) and `IMPALA_SSL=1` (or use regular impala-shell `--ssl` argument pass through)
-`impala_foreach_table.sh` - executes a SQL query against every table, replacing `{db}` and `{table}` in each iteration eg. `select count(*) from {table}`

-`hdfs_checksum*.sh` - walks an HDFS directory tree and outputs HDFS native checksums, MD5-of-MD5 or the portable externally comparable CRC32, in serial or in parallel to save time
-`hdfs_find_replication_factor_1.sh` / `hdfs_set_replication_factor_3.sh` - finds HDFS files with replication factor 1 / sets HDFS files with replication factor <=2 to replication factor 3 to repair replication safety and avoid no replica alarms during maintenance operations (see also Python API version in the [DevOps Python Tools](https://github.com/harisekhon/devops-python-tools) repo)
-`hdfs_file_size.sh` / `hdfs_file_size_including_replicas.sh` - quickly differentiate HDFS files raw size vs total replicated size
-`check_*.sh` - extensive collection of generalized tests that can be applied to any repo (these run against all my GitHub repos via CI)
-`git_for_each_branch.sh` - runs a command on all branches (useful in heavily version branched repos like in my [Dockerfiles](https://github.com/HariSekhon/Dockerfiles) repo)

-`github_api.sh` - querying the GitHub API while inferring github repo from local remotes and authenticating using `$GITHUB_TOKEN` or token from git checkout's remote github url when available. Used as a base for several other scripts that use the GitHub API. Built on top of `curl_auth.sh`
-`github_get_user_ssh_public_key.sh` / `github_get_user_ssh_public_key_api.sh` - fetches GitHub users public SSH keys for quick local installation to `~/.ssh/authorized_keys`
-`github_generate_status_page.sh` - generates a [STATUS.md](https://github.com/HariSekhon/DevOps-Bash-tools/blob/master/STATUS.md) page by merging all the README.md headers for all a user's non-forked GitHub repos or a given list of any repos etc.
-`perl_cpanm_install.sh` - bulk installs CPAN modules from mix of arguments / file lists / stdin, accounting for User vs System installs, root vs user sudo, [Perlbrew](https://perlbrew.pl/) / Google Cloud Shell environments, Mac vs Linux library paths, ignore failure option, auto finds and reads build failure log for quicker debugging showing root cause error in CI builds logs etc
