Hi Expert
Iam using simple command to change root password after MySql installation ,But getting the Above error (signal 9 kill)

script "change password" do
interpreter "bash"
user "root"
cwd "/tmp"
code <<-EOH
#MYSQL
root_temp_pass=$(grep 'A temporary password' /mysql/log/mysqld.log |tail -1 |awk '{split($0,a,": "); print a[2]}')

#Login as root change password
mysql -uroot -p"$root_temp_pass" -Be "ALTER USER 'root'@'localhost' IDENTIFIED BY 'Czt732ck#';" --connect-expired-password
EOH
end

Inspite of the above signal kill command , the password change happened i logged in using new password.But why this error is coming is very confusing.
