This should work :


number_range_like = [ value1,value2,...,valuen ]

How are you going to use it? Maybe you can have a different approach.

Is this what you need?

test[0]=20
test[1]=21
test[2]=22
test[3]=40
echo ${test[*]}

Hi Do you mean a random value?

typeset -i x
typeset -i minrange=20
typeset -i maxrange=40


x=$RANDOM*(maxrange-minrange)+minrange
it will pick a random value in [minrange,maxrange[ interval

Ashan,

You can just use positional values by using "cut" command.

Example:
$ numer_range_like="1,2,3,4,5"
$ echo ${number_range_like} | read second fifth

To see the values:
$ echo $second
$ echo $fifth


FYI,

Ashan,

Sorry, command was incomplete.

$ numer_range_like="1,2,3,4,5"
$ echo ${number_range_like} | tr -s "," " " | read second fifth

To see the values:
$ echo $second
$ echo $fifth
