Shell Programming and Scripting

Hello experts,
I have separate scripts (KSH) each for Solaris and AIX to install core applications (e.g. BigBrother). I also have a script called Installer that gives a menu list to select a particular application to install from a bunch of applications.
Now I am trying to combine separate scripts into a single one so that:

1) when I first run "Installer" script, it will find out whether it is a Solaris or an AIX box
2) run the solaris part of script if it is solaris box and AIX part if it is IBM box from the merged script. (something like jump to AIX script once the installer script finds IBM box or vice versa)


please help me on this

Assume your two scripts are called solaris.sh and aix.sh
Create a wrapper script

Code:

uname | grep -qi aix 
if [ $? -eq 0 ]
      aix.sh
else
      solaris.sh
fi

This assumes you have a POSIX-compliant uname on both systems.

Hello experts,
please help me on this.
This is the scenario:
I have applications like BigBrother,PowerKeeper/PowerBroker etc.. which I have to install during server build for both AIX and Solaris. I already have separate installation scripts for both OS for all applications. Now, I want to merge these separate script (e.g. bigbrotheraix.ksh and bigbrothersolaris.ksh into a single bigbrotherunix.ksh)

From one of my script "installer.ksh", (menu to select the desired application from so many other applications). your above wrapper works fine to select either solaris or aix using 'uname'. I will put this wrapper at the top of installer.ksh script to select OS and print message:: print "you have selected $OS box to install your application. Please select from the menu below to install $OS compatable application"
now when an item is selected from the menu,I should be able to go to the single script containing both solaris and AIX scripts (e.g. bigbrotherunix.ksh) and select solaris part of the script if that turns out to be a solaris box.

thanks for your attention.

Something like this then.

Code:

# early on in the script
uname=$(uname)

# now whenever you need to branch
case $uname in
  AIX)  do aix stuff
        do some more aix stuff;;
  Solaris)
        do solaris stuff;;
esac

You will probably want to experiment a bit with a suitable uname string. I'm guessing it might be uppercase AIX and proper-case Solaris but I don't have easy access to either system to check this.

Hello experts,
1) I have two scripts (one for Solaris and one for AIX), now I want to put these two scripts into a single one.
2) Now I want to run this script (combined) from another script to:
a) select if it is a solaris box or AIX
b) run the solaris part of script from the combined script if the box
comes out to be solaris or vice versa using case-statement.

thanks in advance.

There doesn't seem to be anything here which we haven't answered already. Which parts are you having trouble with?

era,
thanks for responding back.
can you please help me with this one in particular:

Code:

 
OStype='uname -s'
case $OStype in
SUN) commands;;
 
AIX) commands;;
 
esac

Will you please be kind enough to fill up the commands field that
will go to the AIX part of script once OStype=AIX and vice-versa.
I have not changed any thing in the original script but appended AIX script at the bottom of Solaris script.

( I am not so much familiar with scripting,,your help will be really appreciated)

thanks in advance.
