Since MySQL 5.6 AutoMysqlBackup comes back every day with an error mail containing the lines “Warning: Using a password on the command line interface can be insecure.”
Since there is no update of AutoMysqlBackup yet I decided to give it a quick fix myself.
On line 115 there is a line that says
Add this after removeIO:
# Remove annoying warning message since MySQL 5.6
if [[ -s "$log_errfile" ]]; then
grep -v "Warning: Using a password on the command line interface can be insecure." "$log_errfile" > $sedtmpfile
mv $sedtmpfile $log_errfile
And you will receive no more daily emails regarding that it is unsafe to use passwords on the command line.
