Shell Programming and Scripting

Hello,

I am new to korn shell scripting and I would appreciated if someone can help me get started with the following:

I have a text(registry) file which looks like:

1 SOFTWARE 0
4 Clusters 0
0 Application Server 0
0 BasePath 1 /home/new/sso
0 AppPath 1 /home/new/ddd/eso/APPS

and many more.

Here is what i need to do:
1) The first parameter of the script takes the Keyname(second column such as BasePath) as argument.


2) The second parameter of the script should be denote the value of the Key you want returned back to the console. For example, in the following key, if you pass in 4, "/home/new/sso" should be returned to the console.
example: 0 BasePath 1 /home/new/sso

any help with this script will be much appreciated

Try this in a script and see if it works for you:

grep "$1" someFile | cut -f$2 -d" "

oombera thank you very much for your reply. Could you please tell me how this statament works?

Also, some of the rows in the file have invalid entries for the 1st and 2nd parameters such as:

1 GUID 1 {934948494-E768-11D0-8BB0-000A0280D1944}
0 CONN 0 (null)


so i need to check for each parameter to make sure are valid.


once again Thank you very much.

Well, it does what you requested in the first post. Put that line in your script file and then when you call your script file, use something like:

nameOfYourFile BasePath 4

and you'll get returned /home/new/sso

As far as validation, what do you want to check for? How do you determine what's invalid and what's valid? (Not in code, just tell me in plain english what you consider valid and not valid.)

1) for the first parameter the following line:

0 GUID {A84F050...526480000} Module GDS Basic

is invalid since GUID is not a Keyname everything else is valid.


2) for the second parameter the following line:

0 MsgDBPath 1

if I pass in 4 it will error out since there isn't anything to return.


thanks
