esac

# 3  
kindly find below the case command syntax:-

Code:
case "$variable" in
"$condition1" )
command...
;;
"$condition2" )
command...
;;
esac

Notes:-
1-Each test line ends with a right paren ).
2-Each condition block ends with a double semicolon ;;.
3-The entire case block terminates with an esac (case spelled backwards).
4-Quoting the variables is not mandatory, since word splitting does not take
place.
