split string based on delimeter and put them into array using bash script

Question

What is a simple way to split a string and put into an array Here is my string

aa_bb__cc_dd

I would like to have them in an array like this:

array[0] = "aa"

array[1] = "bb"

array[2] = ""

array[3] = "cc"

array[4] = "dd"

Look at this [solution][1], this exactly has what you're looking for. Just use `IFS='_' read -a array <<< "aa_bb__cc_dd"` [1]: http://stackoverflow.com/questions/10586153/bash-split-string-into-array — Máté, Mar 26 '13 at 17:32
