Shell Programming and Scripting

Hi elbombillo,

under bash you assign a variable like

Code:

var="abba"

and an array is pretty similar

Code:

var=( "abba" "acca" adda")

This will give you the array var. You can access the values in var via

Code:

echo ${var[0]} ${var[1]} ${var[2]}

$(...) means run the command between the braces and give me the result.
var=( $(...) ) means run the command between the braces and save the result in an array called var. So should be able to capture the output from any command this way.

For an explanation of [[ -s ... ]] see

Code:

man test

[[ ... ]] && ... || ...

is a short form of if ... then ... else.

If you have other questions you should open a new post a give an exact description of your problem and your goal.

HTH Chris
