Recently I encountered a problem where I had to create couple of arrays in bash and these were quite dynamic in nature. This script was supposed to be used by couple of guys whom I did not trust too much in opening the script and modifyikng the array.

But I found that even after 5 hours I was only 10% done with the data generation. Now that would mean that it would take around 50 hours to complete the data generation.

Tiny Core: Ultralight DIY distribution
When reviewing a lightweight distribution, the term Swiss Army knife is sometimes employed to indicate that it’s packed with features despite a diminutive size.
