- 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`
|
