- Match a variable against string literals to decide which command to run:
|
||||
|
||||
`case {{$tocount}} in {{words}}) {{wc -w README}}; ;; {{lines}}) {{wc -l README}}; ;; esac`
|
||||
`case {{$COUNTRULE}} in {{words}}) {{wc -w README}} ;; {{lines}}) {{wc -l README}} ;; esac`
|
||||
|
||||
- Combine patterns with |, use * as a fallback pattern:
|
||||
|
||||
`case {{$tocount}} in {{[wW]|words}}) {{wc -w README}}; ;; {{[lL]|lines}}) {{wc -l README}}; ;; *) {{echo "what?"}}; ;; esac`
|
||||
`case {{$COUNTRULE}} in {{[wW]|words}}) {{wc -w README}} ;; {{[lL]|lines}}) {{wc -l README}} ;; *) {{echo "what?"}}; ;; esac`
|
||||
|
||||
- Allow matching multiple patterns:
|
||||
|
||||
`case {{$ANIMAL}} in {{cat}}) echo "It's a cat" ;;& {{cat|dog}}) echo "It's a cat or a dog" ;;& *) echo "Fallback" ;; esac`
|
||||
|
||||
- Continue to the next pattern's commands without checking the pattern:
|
||||
|
||||
`case {{$ANIMAL}} in {{cat}}) echo "It's a cat" ;& {{dog}}) echo "It's either a dog or cat fell through" ;& *) echo "Fallback" ;; esac`
