Question

OK, I can’t get this to work for some reason:

if /etc/mysql/my.cfn exist
then goto end;
else bash install.sh;

end exit;;

Answer 1

Here’s a relatively literal translation:

if [ -e /etc/mysql/my.cfn ]; then
    exit # Note: bash does not have a goto command
else
    bash install.sh
fi

Or, eliminate the irrelevant then condition, and invert the test:

if [ ! -e /etc/mysql/my.cfn ]; then
    bash install.sh
fi
