We are building EduLadder(ELADR) - Protocol

The Eladr Protocol is a decentralized, security and efficiency enhanced Web3 noSQL database powered by IPFS as the data storage layer https://ipfs.io/, and the Cardano block chain as the rewards token platform, https://cardano.org/. It provides a JSON based, IPFS layer 2 solution for data indexing and retrieval in an 'append only' file system built with open source Node.js API libraries.

The ELADR token was designed to incentivize and reward community members as a proof of contribution. Token holders are also granted access to EduLadder.com premium features as well as associated ELADR token enabled apps.

Shell (local) variables – Variables that affect only the current shell. In the C shell, a set of these shell variables have a special relationship to a corresponding set of environment variables. These shell variables are user, term, home, and path.

The value could be any type of data such as a name, number, text or filename/directory. So, a variable is nothing more than a pointer to a particular data. A shell allows a user to create, assign or delete variables. ... Also, in Unix, variable  names, like filenames, are case sensitive.
     
       Shell variables are of two types –local and environment. For example, PATH, HOME and SHELL are environment variables. They are called so because they are available in the user's total environment whereas local variables are more restricted in scope.
