scripting

[Sac_3]

Hi everyone,

Need a help on a script. I have explorer script which i need to automate. The script basically collects information about server hardware software etc.
I need to provide inputs to the script (need to automate this with another script). The script needs just an "enter" (to accept the default) for all the Questions that it asks. Is there a way that i can provide the input ("enter" i.e echo -e "/r") to the script in a loop etc whenever it asks for input.

Regards,
SaC

if I understand your question correctly

you have a interactive script ( say explorer.sh) which requires some input at runtime.

you want a way to run this script and leave it unattended and also want the input to be give automatically.

as the default value is taken when enter is pressed.

create a file which has as many lines as there are inpupts/questions in script. say the name of the file is default_input.txt

exceute your script in while loop as

while true
do
explorer.sh < default_input.txt
done

Thanks
Sri

What u understand is correct. Thx for the reply Sri. Im facing an issue while executing the logic that u gave i.e the script shud take input only when it requires/asks, but using this logic it is taking input every time.

So my requirement is, when the script needs input it takes input from input.txt and finally when done shud exit.

I just tested a script like this:

echo "Enter the value for HELLO"
read HELLO
if [ -z "$HELLO" ]
then
HELLO=default
fi
echo $HELLO

echo "Enter the value for GOODBYE"
read GOODBYE
if [ -z "$GOODBYE" ]
then
GOODBYE=default
fi
echo $GOODBYE


Running in this way:

touch answer
./script < answer

It accepts all the default values.
