Why is MySQL Access denied after .bashrc edit?
Never put your password into any script.
The accepted way to do this for MySQL is with a configuration file.

Use a separate configuration file to hold the password.
Protect that file so that you are the only one that can access it.
alias mysql to use that configuration file.

Something like this:
$ ls -ld ~/.milenko.cnf 
-rw------- 1 ... ~/.milenko.cnf 

$ cat ~/.milenko.cnf 
[mysql]
username=milenko
password=REALPASSWORD

In .bash_profile
alias mysql=&quot;/usr/lib/mysql --defaults-extra-file=~/.milenko.cnf --umilenko hlocalhost&quot;
