A hashtable is a data structure which AFAIK isn't available in shell scripting languages... You could use a Python dictionary, a Perl hash, a Lisp hashtable, but I don't think bash or sh have one, mainly because of the purpose those languages have...

If you are looking for a pre-built data structure that is easy to implement, write a Python script

it can be done in bash as well:

but to reiterate:

Was the idea to create a hashtable or hashmap in java, then save the object to disk? Are you talking about running a program from command line or actually scripting something in the terminal?
