clj:tldr:2198b
The command clj is used to start a Clojure REPL (Read-Eval-Print Loop) or to run a Clojure script from the command line.
When you run clj in the terminal, it starts a Clojure REPL environment, which allows you to interactively evaluate Clojure expressions. In the REPL, you can type Clojure code, and it will be immediately evaluated and the result will be printed. This is useful for experimenting, testing code snippets, and debugging.
You can also run Clojure scripts by providing the script file as an argument to the clj command. For example, clj myscript.clj will run the myscript.clj file as a Clojure program.
In both cases, clj provides an environment where you can work with and execute Clojure code, making it easier to write, test, and run Clojure programs.
