will you please provide a solution to this?

Take a range from 0 – 100, find the digits that are repeated twice like 33, 77, etc and store them in an array.

Good collection of examples, especially command output assigning is nice. I wrote somewhat similar but more extensive article on arrays in BASH. Check it out here: wojnowski.net.pl/main/index/arrays-in-bash.

In reply to Gulab.

Hi Gulab,

Sorry for being late..Got stuck with some other work. I would assume that by this time you might have found an answer to your question. Anyway following is my pov.

You can always insert elements into array by referring to the index numbers as I have mentioned in the article. By run time if you mean to have some kind of looping, then you could increment index number for the array within the loop and insert elements one by one. Checking for directory existence is not at all a complex task and you have various methods to do so (easy way: use if conditional statement with test expression parameter -d).
