Using the Jar Command to Unzip Files

Troubleshooting

Problem

This document explains how to decompress a file in the IFS using the "jar" command.

Resolving The Problem

The following syntax shows an example of the Java ARchive ("jar") command, in Qshell, to decompress a compressed file:

To start the Qshell environment, execute "QSH" on a CL command line.

jar -xvf /Directory/File.zip
   -x extract named (or all) files from archive
   -v generate verbose output on standard output
   -f specify archive file name

Note: The 'jar' command extracts to the current directory.

The following is a work-around:

Change the current directory to the target directory before running the jar command:

cd /Target_Directory; jar -xvf /Directory/File.zip

The semicolon ( ; ) is used to separate commands, but to still have them on the same line.

To extract only specific files from an archive, supply their file names:

jar -xvf /Directory/File.zip foo.txt bar.txt

The following example is from an IBM i command line or CL program

Note: This command decompresses only standard compression algorithms.

QSH CMD('cd /Target_Directory;jar -xvf /Directory/File.zip')
