# case
# Branch based on the value of an expression.
# More information: <https://manned.org/case>.

# Match a variable against string literals to decide which command to run:
case $tocount in words) wc -w README; ;; lines) wc -l README; ;; esac

# Combine patterns with |, use * as a fallback pattern:
case $tocount in [wW]|words) wc -w README; ;; [lL]|lines) wc -l README; ;; *) echo "what?"; ;; esac
