Indent by four spaces, not by tabs, or by three spaces.
Use ${varname}, not just $varname.
Put successive commands on separate lines.
Indent case statements in a consistent manner: put case patterns
on their own lines; put ;;s on their own lines.
Replace the [ command with test.
Put quotes around strings that should be considered one word
even if they are empty or contain spaces.
Fix English in messages and comments.
