Condensing A loop

[inforeqd]

First off, thanks for the earlier responses concerning a discussion for shell scripting.

Now

Heres my question. Bourne shell script with the following

echo "Do you want something (y/n)?"

while true;do
read answer
if [ "$answer" = Y -o "$answer" = y ]
then
DO A COMMAND HERE
break
elif [ "$answer" = N -o "$answer" = n ]
then
echo "Skipping to the next step"
break
fi
done


Any suggestions on shortening this alot. I dont want to repeat it througout a script for everytime I want an answer from a user.

Thanks

Inf,

Looks like a good candidate to put in a function. I'll write it for you if you like (or someone else will) -- do you want that or would you prefer to have a go first? Mike
