Korn Shell Arrays

$ colors[0]=RED $ colors[1]=GREEN $ colors[2]=BLUE

Alternatively, you can perform the same assignments using a single command:

$ set -A colors RED GREEN BLUE

Adding a dollar sign and an opening brace to the front of the general syntax and a closing brace on the end allows you to access individual array elements:

${arrayname[subscript]}

Using the array we defined above, let's access (print) each array element one by one:

$ print ${colors[0]} RED $ print ${colors[1]} GREEN $ print ${colors[2]} BLUE $

If you access an array without specifying a subscript, 0 will be used:

$ print ${colors[]} RED $

The while construct can be used to loop through each position in the array:

$ i=0 $ while [ $i -lt 3 ] > do > print ${colors[$i]} > (( i=i+1 )) > done RED GREEN BLUE
