Starting for Loop from second element - Shell script

Question

I want to start iterating over the array from the second element for the below array in shell script.

number=${number:-(12 20 43 45 67 40)}

Could you please help me on how to use the For Loop to iterate starting from the second element (ie 20 in this case)

for i in ${number[@]}

Thanks in advance.

Answer 1

You can use ${number[@]:1} to start iterating from 2nd element:

for i in "${number[@]:1}"; do
    echo "Processing: $i"
done

Answer 2

I usually split the array into $firstLine and $restOfLines like this:

$firstLine, $restOfLines = $sourceArray
foreach($line in $restOfLines) { ... }
