Installation of unzip 5.52 on HP-Ux 11.31

[Shinji Teragaito_1]

You don't install the unzip command. You can use the jar command as follows:

% /opt/java6/bin/jar xvf basic-11.1.0.7.0-hpux-ia64.zip

Perhaps _you_ don't.

dyi # /opt/java6/bin/jar
bash: /opt/java6/bin/jar: No such file or directory

But even if you've installed the optional
Java software, there may still be reasons
to use a real UnZip program. Large files,
for example:

dyi # time unzip6 -l /opt/ziptest/vms732x8.img.zip
Archive: /opt/ziptest/vms732x8.img.zip

In some cases "jar" can do the job, but it
can't always replace a real UnZip program.
