Shell Programming and Scripting

Hi Friends

I am trying to make an interactive shell script ( I do not have expect tool )

My objective is

1.I have a progam named say "inter"
The program when ran on command prompt will be as below

Prompt>inter
Please enter the choice
1.enter 1
2.enter 2
< I need to enter 1 or 2 here >
output will be displayed in screen .

2.I want to make this automated , I want to run this once in 2 minutes and put the output in a file

Could any one give me some idea about how to go about this

Thanks
Siva

Siva,

If you want to automate this process you need to use cron tab in UNIX. You can set it to run every 2 minutes everyday.

Hi

Thanks for the reply

running it periodically is not a problem for me but my query is about making the script interactive

Thanks..Siva

Are you using ksh?

Code:

select myoption in foo bar baz quux
 do
  print "You chose $REPLY."
  break
done

Yields:

Code:

1) foo      
2) bar      
3) baz      
4) quux     
#? 2        
You chose 2.
$

Hi

Thanks for the responce

But I got to know the "here document" function which could solve my problem

The code looks like

inter << END
1
END

The output is

inter
1.enter 1
2.enter 2
1

and that is what I expected

Thanks
Siva
