Extracting the Contents of a JAR File

https://docs.oracle.com/javase/tutorial/deployment/jar/unpack.html

The basic command to use for extracting the contents of a JAR file is:

jar xf jar-file [archived-file(s)]

Let's look at the options and arguments in this command:

  • The x option indicates that you want to extract files from the JAR archive.
  • The f options indicates that the JAR file from which files are to be extracted is specified on the command line, rather than through stdin.
  • The jar-file argument is the filename (or path and filename) of the JAR file from which to extract files.
  • archived-file(s) is an optional argument consisting of a space-separated list of the files to be extracted from the archive. If this argument is not present, the Jar tool will extract all the files in the archive.
  • As usual, the order in which the x and f options appear in the command doesn't matter, but there must not be a space between them.
