If cut was working, it would show the entire result.

Please post the cut command that you are using.

Also, this is a cut question, not a BASH question.

There are much better ways than trying to do string manipulation with bash and small utilities.

I suggest any scripting language that you might be familiar with, for instance perl, php, python etc. It's easy to do what you want with any programming language.

Bash and utilities such as awk, sed, grep, cut etc are excellent for simple, quick and dirty hacks. But when you want to extract data from files and perhaps reformat it, it's much easier to do it with a more suitable tool. Perl in fact was made by a sysadmin for this specific purpose.

So even more reason to use a scripting language then.

Both php and python can read and write json files natively. It looks like perl needs to have a module installed.

Since there is a restriction installing modules in my developer desktop so only trying without python

I understand but using bash and small utilities is like trying to perform surgery with a hacksaw.

I'd look into getting the right tools installed on your desktop before wasting more time on trying to come up with some inflexible bash script.

My personal preference is actually php. A lot of people think it's just for web development and don't realize it's actually a script language that you could use for anything.

Rarely use it for that specifically, but PHP is definitely an awesome general purpose scripting language. I especially like that it is so good for web and great as a gp scripting language. So you get the best of one and one of the best of the other.

I like Python a lot, too. And it covers the same range of things as PHP. But I like PHP better.
