[Level 1] How to install 32 bit java for Juniper VPN in CentOS. 

##
## Precondition: you have to download 32 bit openjdk first!
##

compat_32="compat-libstdc++-296"
libs_for_vpn="xterm ld-linux.so.2 libstdc++.so.6 libz.so.1 libXext.so.6 libXrender.so.1"
java_64_rpms="java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64 icedtea-web-1.4.1-0.el6.x86_64"
libs_for_java_32="giflib.i686 nss.i686 libpng12.so.0 libpulse.so.0 rhino"

java_32_rpm_url="ftp://ftp.muug.mb.ca/mirror/centos/6.5/os/i386/Packages/java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.i686.rpm" 

java_32_rpm="`basename $java_32_rpm_url`"

download_dir="/tmp"

 

## download 32bit java

cd $download_dir; wget $java_32_rpm_url 

 

## remove native openjdk
sudo yum -y remove java-1.7.0-openjdk

## install 32 compatible libraries
for app in $compat_32
do
  sudo yum -y install $app
done

## install libraries for vpn
for app in $libs_for_vpn
do
  sudo yum -y install $app
done

## install 64 bit java
for app in $java_64_rpms
do
  sudo yum -y install $app
done

## setup alternative java
sudo update-alternatives --set java /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java

## install libraries for 32 bit java
for app in $libs_for_java_32
do
  sudo yum -y install $app
done

## install 32 bit java
sudo rpm -ihv $java_32_rpm
Wish this helps.

[Level 2] Shell Interactive With Zenity Episode 5 -- list

If you want to give a list for user to choose, you can use the option "--list". The command synopsis as below: SYNOPSIS      zenity  --list [--title=title] [--window-icon=path] [--width=width]    [--height=height] [--timeout=seconds] [--column=text] [--checklist]       [--radiolist] [--separator=character] [--multiple] [--editable] [--print-column=number] [--hide-column=number] Just like " --calendar ", if you press "ESC" key or click button "Cancel", the return code will be "1". If you select one option and click "OK", zenity will response the option and return the code will be "0".

[Level 2] iif in Python

If you want to implement iif in Python, please refer to the following sample code: #!/bin/env python def iif(b): return 'It\'s True' if b else 'It\'s False' print iif(True) print iif(False) And the following sample, guess what will you get! #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % 'Ture' if b else 'False' Result: $ ./iif.py b: Ture False The second result is "False", not "b: False". Why??? Because the prededence of string concatenation is higher than if. Therefore you need to use () to make it correct. #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % ('Ture' if b else 'False') Wish this helps. regards, Stanley Huang
