jar: Recursively archive all files in the current directory into a .jar file.

$ jar cf ${file-jar} *

try on your machine

This command is used to create a JAR (Java Archive) file.

Here's a breakdown of the command:

jar is the command-line tool used to create, extract, and manage JAR files in Java.
cf is an option for the jar command, where c stands for create and f specifies the name of the JAR file.
${file-jar} is a placeholder for the name of the JAR file you want to create. This can be replaced with the desired name of your JAR file.
* specifies that all files and directories in the current working directory should be included in the JAR file. The * is a wildcard character that represents all files and directories.
