Sometimes I need to ask the user for yes/no to confirm something.
Usually I use something like this:
# Yes/no dialog. The first argument is the message that the user will see.
# If the user enters n/N, send exit 1.
check_yes_no(){
while true; do
read -p "$1" yn
if [ "$yn" = "" ]; then
yn='Y'
fi
case "$yn" in
[Yy] )
break;;
[Nn] )
echo "Aborting..."
exit 1;;
* )
echo "Please answer y or n for yes or no.";;
esac
done;
}
Is there a better way to do it? Is this utility maybe already in my /bin
folder?
select
, but otherwise I don't see a simpler way.
