Files and I/O

Checking if a directory exists

Clojure, being a JVM language, can utilize Java’s java.io.File class for this purpose.

Creating a temporary file

Clojure makes it simple.

Reading a text file

Traditionally, reading files in programming languages was a verbose task with many steps to handle errors and resources.

Reading command line arguments

In Clojure, you snag command line arguments with command-line-args.

Writing a text file

The spit function is the simplest way to write text to a file in Clojure.

Writing to standard error

In Clojure, you can write to stderr using the err stream.
