 Command Line Artificial Intelligence `CLAI` is an open-sourced project aimed to bring the power of AI to the command line. Using CLAI, users of Bash can access a wide range of skills that will enhance their command line experience. This repository contains the source code and documentation to get you started.

 This skill lets you specify tasks in English and retrieve their command line syntax. 
 Currently supported tasks include compressing and uncompress archives 
 using `tar` and looking for strings in files using `grep`.

-No one remembers arcane flags to commands we use every day.
-The ability to turn natural language instructions to bash commands has been a pipe 
-dream for the research community for a while. 
-After all, there is a lot of data already out there in public forums and in documentation
-that can be readily leveraged. 
-Especially with recent advances in natural language processing, 
-this problem has received renewed interest.

-Most recent attempts (including the ones above) are either heavily rule based or

-As such, it remains an open challenge today.
