Bash: the #1 Skill of a DevOps Engineer
summary
Argues Bash is the most practical glue for DevOps and shows working examples: small scripts that read stdin, set -e -o pipefail, debug with set -x, and trap cleanup. Demonstrates token caching via a timestamped file, version bumping with sed git commit and tag, and extracting data with curl + jq + awk. Notes limits — avoid >100 lines or heavy data structures — and shows file-watchers (entr/watch) and that these scripts actually run in CI containers.
