You are using *.txt. Sorry!

Did you notice from your example?

Code:

item 0: android : Audio <--
item 1: Audio<-- : bin <--
item 2: bin<-- : build <--
item 3: build<-- : Calibre

Not sure what you mean?

You deleted your post but anyway.

Code:

i=0
next=0
for i in ${!a[@]}; do
	next=$(($i + 1))
	echo "item $i: ${a[$i]} : ${a[$next]}"
done

The script outputs values as below so you are repeating items.
item 0: a[0] : a[1]
item 1: a[1] : a[2]
item 2: a[2] : a[3]

One possible fix.

Code:

for (( i=0; i<${#a[@]}; i+=2 )); do
  next=$(($i + 1))
  echo "item $i: ${a[$i]} : ${a[$next]}"
done

Thanks a LOT (really! A LOT!!) for all your time. I'm so sorry I forgot that this post was kept open. robertjinx's script did what I was trying to do.
