Poem

In a shell, a message clear and bright,
"Demo on docker..!" echoes in the night.
With Bash as my guide, I script and I play,
Hopping through containers, I code all day.

docker-demo.sh (2)

1-2: Add defensive Bash flags for safer scripts

Even for a demo it’s good habit to fail fast on errors and undefined variables.

 #!/bin/bash
+set -euo pipefail
 echo "Demo on docker..!"

This single line prevents accidental silent failures from creeping into future edits.

---

2-2: Prefer printf over echo for portable, predictable output

echo implementations differ (e.g., handling of -n, escape sequences). printf is POSIX-consistent.

-echo "Demo on docker..!"
+printf '%s\n' "Demo on docker..!"

Not critical here, just a best-practice tip.
