Menu help with array selection

draco · #1 (**permalink**) 10-10-2008

Hi there all

I got the following
I got multiple arrays named for example
STAT_AAAA
STAT_AAAB
STAT_AAAC
STAT_AAAD

Now what I want I have chosen an option in a menu to select 1
but I dont want to write for all the same thing so I made it a signle one
now what I want is to get
STAT_ and than the selected one
How is this done?
so example
${STAT_AAAA} AAAA should be able to change by selection..
I got AAAA and AAAB also in a variable.
${STAT_ *Variablename*[2]}
how can this be done?
Many thanx in advance!

Code:

eval "printf '%s\n' \"\${STAT_$VAR[2]}\""

Oke and how do I use it like that than?

What do you want to do with it?

To store it in a variable:

Code:
eval "value=\${STAT_$VAR[2]}"

Can I use an array in an array??
So I can use someting multiple times instad of making for every array the same?

As in
${array${array[*][1]}}

I got this now but maybe I can make someting much easyer for this wich also cost less lines

So if I would put the 4 letter words such as XFWT in an array aswell and than call it up inside an array...
If I make anny sense that is :P

Code:

if [ ${STAT_XFWT[2]} = "running" ]
then
        STAT_XFWT[2]='\033[1;32mRunning\033[m'
else
        STAT_XFWT[2]='\033[1;31mStopped\033[m'
fi

if [ ${STAT_XMCT[1]} = "up" ]
then
        STAT_XMCT[1]='\033[1;32mUP\033[m'
else
        STAT_XMCT[1]='\033[1;31mDown\033[m'
fi

if [ ${STAT_XMCT[2]} = "running" ]
then
        STAT_XMCT[2]='\033[1;32mRunning\033[m'
else
        STAT_XMCT[2]='\033[1;31mStopped\033[m'
fi

if [ ${STAT_XMCA[1]} = "up" ]
then
        STAT_XMCA[1]='\033[1;32mUP\033[m'
else
        STAT_XMCA[1]='\033[1;31mDown\033[m'
fi

if [ ${STAT_XMCA[2]} = "running" ]
then
        STAT_XMCA[2]='\033[1;32mRunning\033[m'
else
        STAT_XMCA[2]='\033[1;31mStopped\033[m'
fi

if [ ${STAT_ZAMI[1]} = "up" ]
then
        STAT_ZAMI[1]='\033[1;32mUP\033[m'
else
        STAT_ZAMI[1]='\033[1;31mDown\033[m'
fi

if [ ${STAT_ZAMI[2]} = "running" ]
then
        STAT_ZAMI[2]='\033[1;32mRunning\033[m'
else
        STAT_ZAMI[2]='\033[1;31mStopped\033[m'
fi

No shell that I know of has multidimensional arrays (but awk does).

You can use the contents of an array as an element in another array, but it will no longer be an array. You may be able to reconstruct an array from it.

For example:

Code:
a1=( 1 2 3 4 5 6 7 8 )
a2=( a b c d e f g h )
b=( "${a1[*]}" "${a2[*]}" )
printf "%s\n" "${b[@]}"
