Solution 1

Here is the script based on @A.B. answer.

This script installs Oracle java 8 64-bit. On each run it checks version and updates java to the latest available.

It can be placed to cron.daily or cron.weekly, to check for updates.

#!/bin/sh

J_INSTALL_DIR=/usr/lib/jvm/java-8-oracle

URL=$(curl -s http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html | \
    awk "/downloads\['/ && ! /demos/ && /\['files'\]/ && /linux-x64/ && /\.tar\.gz/" | \
    grep -o 'http.*\.tar\.gz') 

AVAILABLE=$(echo $URL | grep -o -P 'jdk-8u.{0,2}' | cut -d "u" -f 2)
CURRENT=$("$J_INSTALL_DIR"/bin/java -version 2>&1 | awk '/version/ {print $3}' | cut -d_ -f 2 | tr -d '"')

if [ -z $CURRENT ] || [ $AVAILABLE -gt $CURRENT ]; then
    cd /var/cache/oracle-jdk8-installer
    rm -f jdk-8u"$CURRENT"-linux-x64.tar.gz
    wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" $URL
    tar -xzf jdk-8u"$AVAILABLE"-linux-x64.tar.gz
    rm -rf $J_INSTALL_DIR
    mv jdk1.8.0_"$AVAILABLE"/ $J_INSTALL_DIR

    LATEST=$(LANG=C update-alternatives --display java | grep ^/ | sed -e 's/.* //g' | sort -n | tail -1)
    if [ -z $LATEST ]; then
        LATEST=1
    else
        J_PATH=$(LANG=C update-alternatives --display java | grep "priority "$LATEST"" | awk '{print $1}')
        [ $J_PATH = "$J_INSTALL_DIR"/jre/bin/java ] || LATEST=$((LATEST+1))
    fi  

    #link JRE files
    for f in $J_INSTALL_DIR/jre/bin/*; do
        name=`basename $f`;
        if [ ! -f "/usr/bin/$name" -o -L "/usr/bin/$name" ]; then  #some files, like jvisualvm might not be links
            if [ -f "$J_INSTALL_DIR/man/man1/$name.1.gz" ]; then

                update-alternatives --install /usr/bin/$name $name $J_INSTALL_DIR/jre/bin/$name $LATEST --slave /usr/share/man/man1/$name.1.gz $name.1.gz $J_INSTALL_DIR/man/man1/$name.1.gz
            fi
        else     
                update-alternatives --install /usr/bin/$name $name $J_INSTALL_DIR/jre/bin/$name $LATEST

        fi
    done

    echo "Oracle Java 8 installed"

fi

if [ $AVAILABLE -eq $CURRENT ]; then
    echo "Java is up to date"
fi

To test it now, you can set CURRENT=45 in the script.

But some minor improvements can be done, like fontconfig.

The script can be downloaded from github too.

Pull requests and complaints are welcome.

Solution 2

The script works in conjunction with the WebUpd8 PPA. Therefore install Java by the PPA first.

If there is a new version in the PPA, then this is installed via the package manager. In the meantime, the script can install a newer version, it there is a new version on the Oracle website.

A few considerations

Download a version via wget, eg:

wget --no-cookies --header \
    "Cookie: oraclelicense=accept-securebackup-cookie" \
    $URL

Get the URL with (for linux-x64 and tar.gz)

URL=$(curl -s http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html | \
    awk "/downloads\['/ && ! /demos/ && /\['files'\]/ && /linux-x64/ && /\.tar\.gz/" | \
    grep -o 'http.*\.tar\.gz')

All in one

for Oracle Java 8 via the URL http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

wget --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" \
    $(curl -s http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html | \
        awk "/downloads\['/ && ! /demos/ && /\['files'\]/ && /linux-x64/ && /\.tar\.gz/" | \
        grep -o 'http.*\.tar\.gz'\
    )

Explanation

  • /downloads\['/ – We need the downloads area

  • /\['files'\]/ – We need the files area

  • /linux-x64/ – The target architecture

    That you could adapt.

  • /\.tar\.gz/ – The file format

    That you could adapt.

    If you do that, don't forget the tar.gz in grep -o 'http.*\.tar\.gz'

  • ! /demos/ – No demos

The script for Oracle Java 8, x64, tar.gz

#!/bin/bash
major_version="8"
target="/usr/lib/jvm/java-8-oracle"
arch="linux-x64"

# This URL is for the major version 8.
download_page="http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html"

download_url=$(curl -s "$download_page" | \
        awk "/downloads\['/ && ! /demos/ && /\['files'\]/ && /$arch/ && /\.tar\.gz/" | \
        grep -o 'http.*\.tar\.gz')

server=$(awk -Fjdk-"$major_version"u '{split($2,a,/-/); print a[1]}' <<< "$download_url")
local=$("$target"/bin/java -version 2>&1 | awk -F_ '/java version/ {gsub(/"/,""); print $2}')

[ "$local" == "" ] && local=0

filename=$(awk -F'\/' '{print $NF}' <<< "$download_url")

[ "$server" -gt "$local" ] && wget -q -P "/tmp" --no-cookies --show-progress --header \
    "Cookie: oraclelicense=accept-securebackup-cookie" \
    "$download_url" 

if [ -f "$filename" ]; then
    mkdir -p "$target"
    tar -xf "$filename" --strip 1 -C "$target"
fi

exit 0

Useful

List all architectures and file formats with this command:

curl -s http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html | \
        awk "/downloads\['/ && ! /demos/ && /\['files'\]\['jdk/"

    The popular WebUpd8 Team PPA is not being updated.

    It has still obsolete versions like 8u45.

    I manually downloaded JDK from Oracle site and replaced it.

    Is there a way to automatically check Oracle java latest version and download it, if it has been updated?

    I see the main problem is to download it. I looked in oracle-java8-installer scripts and see some weird links they download it from.

    The tarball can't be downloaded directly from Oracle site without accepting a license. The installer checked that too. But I do not quite get how to accept the license from command line.

    This script could be added to cron.

    Just in case the PPA is never updated, or if there are delays like this time.

      Hmm, looks interesting =)

      you can download it by accepting the license when providing special cookie. This can be passed as additional parameter to wget/curl

      @ibre5041 Can you make at least a download script? But I can't find a permanent download link.

      One question: would a script that checks the latest downloaded version (downloaded from the script itself) be enough? I.e.: a script that will just download the latest version the first time and that won't download anything more until a new version it's released

      @kos I check java version. Look at my answer pls.
  • Pilot6

    Thx. The next real problem is how to guess a link to the next release. The last one was ...8u45-b14.... Maybe test all `bnn?

    @Pilot6 I am still pondering on =\

    @A.B. I got it. Now some checks for existing files or dirs may be added.

    And also this can be done with update-alternatives to a fresh install without that deb from ppa.

    @A.B. This looks better. But does same.

    java -version is a bad idea if you have multiple java versions installed and the default Java isn't Oracle Java.
  • A.B.
    A.B. almost 9 years
    sorry, here comes the smile :)

    @A.B. Hey, no worries ;). Yes it does assume a single installation of Oracle Java, I've mentioned this in the "Caveats" section.
  • A.B.

    Someone gave us downvotes. :(

    You know what? I am not sure that the link jdk8-downloads-2133151.html will stay after they update the version.
  • Pilot6
    Pilot6 almost 9 years
    So the whole point does not make sense. They change it every time. Someone has to update link, like it is done in the ppa.

    @Pilot6 A new link for each new version? o_O
