UPPERCASE words are placeholders to replace. Brackets in the syntax line describe optional arguments; do not type those brackets literally.
for NAME in WORDS; do COMMANDS; doneExample
for city in Munich Bucharest; do printf "%s\n" "$city"; doneExpected result
Munich and Bucharest on separate lines.
Notes and traps
Quote variable expansions; for file in $(ls) breaks on ordinary filenames.
