Learning Bash Best Practices - 03 // The problems with bash functions, parsing a CSV, unit testing

[@alexanderelgert6037]

you could use IFS=',' to tokenize the csv line:
$ echo 'a,b,c' | { declare -a line; IFS=',' read -ra line ; declare -p line; }
declare -a line=([0]="a" [1]="b" [2]="c")
additionally the case accepts a leading bracket, which is very practical
('h'|'help') ... ;;
