Java-Update-Script

Basiernd auf http://webupd8.googlecode.com/files/update-java habe ich ein modifiziertes Scritp erstellt, welches auf der Commandline läuft und aus Dateien auch Java aspackt.

Das Script kann mit der zu installierenden Datei al Parameter aufgerufen werden. Ohne Parameter kann man eine Datei auswählen.

Installation

wget -O /usr/local/bin/update-java "https://wiki.mhcsoftware.de/_export/code/java-update-script?codeblock=1"
chmod +x /usr/local/bin/update-java

#update-java VERSION 0.2beta
#Linux Java update script: Remove old versions, point default at latest version

#Copyright 2010, Bruce Ingalls GPL 3 Affero see http://www.gnu.org/ for details
#Downloads & discussion at http://www.webupd8.org/
#Contact bingalls at users dot sf dot net for licensing & additional help
#Currently supports Ubuntu, only. Likely less useful for RPM based Linux distros.
#Currently supports only full java jdk, not jre.
#Note that update-alternatives by default misses many java tools, such as 'jar'
#Known bugs:
#  Cancelling takes half a minute.
#  Sun does not install JRE in a standard location
#  Gkmsgs cannot handle spaces
#  Does not check for Japanese environment & man pages
