Quick Setup

To bootstrap, install packages and link in to your shell profile to inherit all configs, do:

curl -L https://git.io/bash-bootstrap | sh

Adds sourcing to .bashrc/.bash_profile to automatically inherit all .bash.d/*.sh environment enhancements for all technologies (see Inventory below)
Symlinks .* config dotfiles to $HOME for git, vim, top, htop, screen, tmux, editorconfig, Ansible, PostgreSQL .psqlrc etc. (only when they don't already exist so there is no conflict with your own configs)
Installs OS package dependencies for all scripts (detects the OS and installs the right RPMs, Debs, Apk or Mac HomeBrew packages)
Installs Python packages
Installs AWS CLI

To only install package dependencies to run scripts, simply cd to the git clone directory and run make:

git clone https://github.com/HariSekhon/DevOps-Bash-tools bash-tools
cd bash-tools
make

make install sets your shell profile to source this repo. See Individual Setup Parts below for more install/uninstall options.

More Linux & Mac

bin/, install/, packages/, setup/ directories:

Linux / Mac systems administration scripts:
- install/ - installation scripts for various OS packages (RPM, Deb, Apk) for various Linux distros (Redhat RHEL / CentOS / Fedora, Debian / Ubuntu, Alpine)
- 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 tarballs, Golang binaries, random 3rd party installers, Jython and build tools like Gradle and SBT for when Linux distros don't provide packaged versions or where the packaged versions are too old
- packages/ - OS / Distro Package Management:
  - install_packages.sh - installs package lists from arguments, files or stdin on major linux distros and Mac, detecting the package manager and invoking the right install commands, with sudo if not root. Works on RHEL / CentOS / Fedora, Debian / Ubuntu, Alpine, and Mac Homebrew. Leverages and supports all features of the distro / OS specific install scripts listed below
  - install_packages_if_absent.sh - installs package lists if they're not already installed, saving time and minimizing install logs / CI logs, same support list as above
  - Redhat RHEL / CentOS:
    - yum_install_packages.sh / yum_remove_packages.sh - installs RPM lists from arguments, files or stdin. Handles Yum + Dnf behavioural differences, calls sudo if not root, auto-attempts variations of python/python2/python3 package names. Avoids yum slowness by checking if rpm is installed before attempting to install it, accepts NO_FAIL=1 env var to ignore unavailable / changed package names (useful for optional packages or attempts for different package names across RHEL/CentOS/Fedora versions)
    - yum_install_packages_if_absent.sh - installs RPMs only if not already installed and not a metapackage provided by other packages (eg. vim metapackage provided by vim-enhanced), saving time and minimizing install logs / CI logs, plus all the features of yum_install_packages.sh above
    - rpms_filter_installed.sh / rpms_filter_not_installed.sh - pipe filter packages that are / are not installed for easy script piping
  - Debian / Ubuntu:
    - apt_install_packages.sh / apt_remove_packages.sh - installs Deb package lists from arguments, files or stdin. Auto calls sudo if not root, accepts NO_FAIL=1 env var to ignore unavailable / changed package names (useful for optional packages or attempts for different package names across Debian/Ubuntu distros/versions)
    - apt_install_packages_if_absent.sh - installs Deb packages only if not already installed, saving time and minimizing install logs / CI logs, plus all the features of apt_install_packages.sh above
    - apt_wait.sh - blocking wait on concurrent apt locks to avoid failures and continue when available, mimicking yum's waiting behaviour rather than error'ing out
    - debs_filter_installed.sh / debs_filter_not_installed.sh - pipe filter packages that are / are not installed for easy script piping
  - Alpine:
    - apk_install_packages.sh / apk_remove_packages.sh - installs Alpine apk package lists from arguments, files or stdin. Auto calls sudo if not root, accepts NO_FAIL=1 env var to ignore unavailable / changed package names (useful for optional packages or attempts for different package names across Alpine versions)
    - apk_install_packages_if_absent.sh - installs Alpine apk packages only if not already installed, saving time and minimizing install logs / CI logs, plus all the features of apk_install_packages.sh above
    - apk_filter_installed.sh / apk_filter_not_installed.sh - pipe filter packages that are / are not installed for easy script piping
  - Mac:
    - brew_install_packages.sh / brew_remove_packages.sh - installs Mac Hombrew package lists from arguments, files or stdin. Accepts NO_FAIL=1 env var to ignore unavailable / changed package names (useful for optional packages or attempts for different package names across versions)
    - brew_install_packages_if_absent.sh - installs Mac Homebrew packages only if not already installed, saving time and minimizing install logs / CI logs, plus all the features of brew_install_packages.sh above
    - brew_filter_installed.sh / brew_filter_not_installed.sh - pipe filter packages that are / are not installed for easy script piping
    - brew_package_owns.sh - finds which brew package owns a given filename argument
all builds across all my GitHub repos now make system-packages before make pip / make cpan to shorten how many packages need installing, reducing chances of build failures

Builds, Languages & Linting

bin/, checks/, cicd/ or language specific directories:

lint.sh - lints one or more files, auto-determines the file types, parses lint headers and calls appropriate scripts and tools. Integrated with my custom .vimrc

check_*.sh - extensive collection of generalized tests - these run against all my GitHub repos via CI. Some examples:
- Programming language linting:
  - Python (syntax, pep8, byte-compiling, reliance on asserts which can be disabled at runtime, except/pass etc.)
  - Perl
  - Java
  - Scala
  - Ruby
  - Bash / Shell
  - Misc (whitespace, custom code checks etc.)

    make azure-shell            sets up Azure Cloud Shell (limited compared to gcp-shell, doesn't install OS packages since there is no sudo)

Now exiting usage help with status code 3 to explicitly prevent silent build failures from stray 'help' arguments
make: *** [help] Error 3

(make help exits with error code 3 like most of my programs to differentiate from build success to make sure a stray help argument doesn't cause silent build failure with exit code 0)
