get index of an element in array in bash

mangatmodi · 11-19-2009, 08:23 AM

I have an array say

Code:

array_name=( XXX YYY ZZZ aaa bbb ccc)

and I want to get Index of aaa. Is there any function or a simple way, other than looping, to get Index of an element of an array.

I don't want to use loop, since it is a part of a larger program and looping will really make it complex

I'm using GNU bash, version 3.2.33(1)-release (i386-redhat-linux-gnu)

Code:

echo ${!array_name[@]}

Sir thank you for your reply but I still didn't get it. The above code give me following output

Code:

0 1 2 3 4 5

But how can I deduce from it that 3 is the Index of aaa ?

do it loop. Its really not that complex. after you done it, make a function out of it, so that next time, you can use it again
