How about this using the shell select internal

Code:
listofitems="beans rice carrots radishes rutabaga spinach"
MU=( $listofitems Quit )

while true
do
    echo "Please enter the veg you like from"
    select opt in "${MU[@]}"
    do

        if [ "$opt" != "" ]
        then
            echo "You selected $opt"
            break 3
        fi
        # Check REPLY against the array:
        for opt in ${MU[@]}
        do
           if [ $REPLY = "$opt" ]
           then
               echo "You selected $opt"
               break 3
           fi
        done
        echo "Illegal selection"
        break
    done
done

NAME
ocamldsort - Dependency sorter for OCaml source files SYNOPSIS
ocamldsort [ -pp pre-command ] [ -d dep-command ] [ -mli ] [ -nox ] [ -obj | -byte | -opt ] [ filename ] ... DESCRIPTION
The ocamldsort(1) command scans a set of Objective Caml source files (.ml and .mli files), sorts them according to their dependencies and prints the sorted files in order to link their corresponding .cmo files. For ocamldsort(1) to work it must get a list of dependencies generated by ocamldep(1), if the standard input to ocamldsort(1) has been redirected then ocamldsort assumes that this is a dependency file generated by ocamldep(1). Otherwise ocamldsort calls ocamldep(1) to gen- erate the dependency list itself. In either case the source files to be sorted should be given as arguments to the ocamldsort(1) command. ocamldsort(1) can be used to compile and link simple projects with one command, such as: ocamlc $(ocamldsort *.ml) if your project doesn't contain .mli files or: ocamlc -c $(ocamldsort -mli *.ml *.mli) && ocamlc $(ocamldsort -byte *.ml) if it contains .mli files. However for larger projects where separate compilation is desirable, ocamldsort(1) can also be used from within a makefile. Here is a typi- cal makefile example: TARGET=my_program OCAMLC=ocamlc OCAMLOPT=ocamlopt OCAMLDEP=ocamldep OCAMLDSORT=ocamldsort PPFLAGS=-pp camlp4o MLY=$(shell echo *.mly) MLL=$(shell echo *.mll) GENERATED_ML=$(MLY:.mly=.ml) $(MLL:.mll=.ml) include .generated .depend .ocamldsort $(TARGET): $(CMO_FILES) $(OCAMLC) $(COMPFLAGS) $(LIBS) $^ -o $@ $(TARGET).opt: $(CMX_FILES) $(OCAMLOPT) $(COMPFLAGS) $(LIBS_OPT) $^ -o $@ .generated: $(GENERATED_ML) @touch .generated .depend: .generated $(OCAMLDEP) *.ml *.mli > $@ .ocamldsort: .depend echo CMO_FILES=`< .depend $(OCAMLDSORT) -byte *.ml` > .ocamldsort echo CMX_FILES=`< .depend $(OCAMLDSORT) -opt *.ml` >> .ocamldsort distclean: clean rm -f .generated .depend .ocamldsort rm -f $(GENERATED_ML) rm -f *~ rm -f $(TARGET) clean: rm -f *.cmo *.cmi *.cmx *.o .SUFFIXES: .mli .ml .cmi .cmo .cmx .mll .mly %.cmi:%.mli $(OCAMLC) $(PPFLAGS) $(COMPFLAGS) -c $< %.cmo:%.ml $(OCAMLC) $(PPFLAGS) $(COMPFLAGS) -c $< %.cmi %.cmo:%.ml $(OCAMLC) $(PPFLAGS) $(COMPFLAGS) -c $< %.cmx %.o:%.ml $(OCAMLOPT) $(PPFLAGS) $(COMPFLAGS) -c $< %.ml:%.mll $(OCAMLLEX) $< %.mli %.ml:%.mly $(OCAMLYACC) -v $< OPTIONS
The following command-line options are recognized by ocamlsort(1): -I directory Add the given directory to the list of directories searched for source files. -pp pre-command Command to preprocess file. -d dep-command Command to compute dependencies. ocamldep(1) by default. -mli Sort files using mli dependencies. -nox Ignore filenames containg `*' so that unexpanded wildcards are ignored. -obj Print bytecode filenames (.cmo and .cmi) (deprecated: use -byte). -byte Print bytecode filenames (.cmo and .cmi). -opt Print opt filenames (.cmx and .cmi). -v Output version information and exit. -help, --help Output help and exit.
