Shell Programming and Scripting

Hi Gurus,

I am new to this unix world...I need your help to walk through.

I want to learn shell scripting..... The shell script which can be able to use with oracle pl/sql...
So please suggest me which shell is good.

Which Unix/Linux version is good for this to Install to get practice the script.
[Is puppy Linux suite for this - give me a clear idea].

Even after Installation of the Unix/Linux OS, do I need to install the shell separately.

Please guide me and suggest me the study materials of shell scripting.

Also send me the study guides to my mailaddress

Thanks In Advance,
Ganesh

It doesn't matter what shell you use. PL/SQL runs inside SQL*Plus, which is a separate program and has nothing to do with the shell.

If you mean for the purposes of practicing with the shell, any mainstream distribution will do. I have no idea what "Puppy Linux" is. For PL/SQL go to the Oracle website to see which Linux distributions they support, then go to the download site for that distribution and fetch a copy. For the purposes of learning shell, or PL/SQL, it doesn't matter which one you chose.

No. Bash is the default shell in Linux. It's a powerful shell, and you don't need to install it. If, for some reason, you'd prefer to use another shell, then you might have to install it. Whatever you do do not start off using the C-Shell.

There are plenty of resources both here (if you have specific difficulties) or on the internet (for general research).

Please, as per the rules you agreed to when you registered, do not post your email address seeking personal responses.

Hey Scott,

Thank you very much..

I will start with Bash as per you advice...I need more advice and help from you in future.

I plan to Install Redhat and need to practice on the basic commands first.

So we can able to do the things in bash what are all possible in other shells also - correct me if I wrong

I don't know why csh is said - so harmful to get the things do.

As a guru I need your help and you please make me to walk on this.

I am also pretty new to this scripting as well. I have found some bash script files from a legacy software. I need to find out the meaning. Could anyone help me regarding the following line:

LOGFILE=/export/home/test/log/test1.log

where and how this log file is being saved and why this line is required to write scripts in UNIX environment?

Very eagerly waiting. Thanking in advance.

@GaneshAnanth. Please do not bump posts if they are not answered promptly.

Please provide more information about your environment. Which OS you are using; is it 32- or 64-bit; do you plan to install Linux on a stand-alone, physical machine, or in a VM; which architecture does the host machine have (32- or 64-bit); how much memory does it have; how many CPU's / cores does it have.

I would start by downloading an ISO image of CentOS (which one depends on answers to the above questions) (I don't know why you'd want to install Oracle on Puppy Linux, or any other cut-down distribution. Stick to what Oracle supports, or at least a rebrand of a popular, fully supported distro.). You can easily find CentOS by searching the internet for it (www.centos.org - The Community ENTerprise Operating System - pick a mirror near you (You're looking for the two DVD images (i.e. like here))).

If you're installing into a VM, point the CD/DVD to the first ISO file (if you're installing it on a physical machine, you may need to burn the ISO to a DVD).

Make sure the machine has around 700MB of memory if you want to use the GUI installer. You'll need about 6GB of diskspace to comfortably install CentOS with the desktop option. The installation process itself is well described along the way. Don't worry about funny stuff like networks, and other software. Just install the OS first, then we can fix it up as you want.

So, it goes something like this:
If you need to install some virtualisation software, there's various options. Oracle's VirtualBox is free - there may be others.

On the other hand, if all you really want is to learn shell scripting, or Oracle is already installed on a remote server, install Puppy using the instructions on their website.

@sMark31: Don't 'hijack' others threads. Please create a new one. Thanks.

Thank you Scott.
I have started a new thread name: "Include logfile in scripts".
Could you please reply?
