Learn to find help in the Linux terminal using ls --help and man pages, mix switches like -l and -R, and use apropos to locate commands.

Master the find command to locate files and folders using -name, -iname, -mtime, -size, and -perm, then combine conditions with and, or, and not for precise searches.

Learn to use grep and egrep with regex patterns to search text, including case sensitivity, ignore-case (-i), and patterns for starting with, ending with, or matching multiple occurrences.

Explore Linux file permissions, using octal values and umask to set default rights, and modify permissions with chmod, including adding execute to scripts and verifying permissions after changes.

Master zsh profile workflows with exports and aliases, stored in GitHub, and accelerate cloud tasks using gcloud and kubectl aliases for GCE, compute, and GKE.

Create a quick get command utility to search across notes and files for gcloud roles and kubectl commands, saving minutes and boosting efficiency in daily SRE workflows.

Explore how to find and verify Google Cloud IAM roles with a specific permission using gcloud commands, grep filtering, and a bash script to enforce least privilege.

Explore practical bash scripting with examples of a get command utility and a get roles by permission utility, including if-else and for loops to automate file processing.

Explore why automation matters for site reliability engineering and infrastructure as code, and see practical bash utilities like get cmd and get roles, plus zsh profile customization to reduce toil.

Explore gcloud, the Google Cloud command line interface, to manage GCP resources from the CLI, automate tasks, and format, filter, and sort outputs using interactive help.

Learn to filter and sort gcloud compute machine types by zone and specs, using exact and partial searches, wc counting, and sorting by cpus and memory.

Explore how to leverage Google Cloud official documentation, cheat sheets, and CLI interactive help to list, describe, and filter compute instances for targeted insights.

Connect to your GKE cluster with gcloud credentials and verify the current kubectl context. Set the default namespace to ECP to run deployments in that namespace.

Learn to use kubectl for version checks, cluster info, and deployment management in production Kubernetes environments. Discover helpful commands, aliases, and resources for creating, exposing, and scaling pods and deployments.

Deploy an nginx pod with kubectl, expose it as a load balancer, test with curl, and clean up, while contrasting imperative commands with declarative configuration and CI/CD.

Recaps connecting to the GKE cluster and kubectl usage, with json, yaml, and jsonpath outputs for deployments, pods, and services, declarative and imperative deployment, and troubleshooting with describe and logs.

Master the vi editor on Unix-like systems through command-line navigation, editing, search and replace, and configuration, with a practical cheat sheet for Linux workflows.

Explore vim editing basics for editing files: insert modes with i, I, a, A, o, O; delete commands like dd, 5dd, dw, D; and copy-paste with yy, p, and P.

Explore how to use the VI editor for search and replace, including case-sensitive and case-insensitive searches, with examples like replacing Carolina with India and undoing changes.

Configure vim by creating a vim profile (vimrc) in your home directory, set default options like set number and set ignore case, and make these changes permanent.

Navigate vim with j k h l w b g G, edit with i o dd y p, search with /, set and make permanent in vim profile.
