What I am doing is creating a top menu, which a user will select a choice with a number entry. That number corresponds to a string in an array. I then want to assign that response to another array I've already declared.
For example:
************
From there, the user will enter 1, 2 or 3. How do I then assign the value of say colors[2] to my array $yellow that I have already declared?
I'm sure this is easy, but I cannot figure this out. And yes, I'm new to scripting.

alphasort
SCANDIR(3) Library Functions Manual SCANDIR(3)NAME
scandir, alphasort - scan a directory
SYNOPSIS
#include <sys/types.h>
#include <sys/dir.h>
scandir(dirname, namelist, select, compar)
char *dirname;
struct direct *(*namelist[]);
int (*select)();
int (*compar)();
alphasort(d1, d2)
struct direct **d1, **d2;
DESCRIPTION
Scandir reads the directory dirname and builds an array of pointers to directory entries using malloc(3). It returns the number of entries
in the array and a pointer to the array through namelist.
The select parameter is a pointer to a user supplied subroutine which is called by scandir to select which entries are to be included in
the array. The select routine is passed a pointer to a directory entry and should return a non-zero value if the directory entry is to be
included in the array. If select is null, then all the directory entries will be included.
The compar parameter is a pointer to a user supplied subroutine which is passed to qsort(3) to sort the completed array. If this pointer is
null, the array is not sorted. Alphasort is a routine which can be used for the compar parameter to sort the array alphabetically.
The memory allocated for the array can be deallocated with free (see malloc(3)) by freeing each pointer in the array and the array itself.
SEE ALSO directory(3), malloc(3), qsort(3), dir(5)DIAGNOSTICS
Returns -1 if the directory cannot be opened for reading or if malloc(3) cannot allocate enough memory to hold all the data structures.
