Automate everything with Bash, Zsh, and command-line tools
Shell scripting (primarily Bash) is the universal automation language for Unix/Linux systems. From deployment scripts and cron jobs to data processing pipelines and system administration, shell scripting is the fastest way to automate repetitive tasks and glue tools together. Every DevOps engineer, backend developer, and system administrator needs shell scripting proficiency. Combined with tools like sed, awk, grep, jq, and curl, shell scripts handle surprisingly complex workflows.
