I've got stuck with it.
I try to edit path in order to work with mysql from iTerm.
I tried different ways to edit my PATH:
1) typing command in terminal export PATH="/usr/local/mysql/bin:$PATH"
2) edit .bash_profile
3) edit .bashrc
Everything works pretty well until I restart my Mac.
Here is what my constant PATH looks like
echo $PATH
/Users/lyubakov/.nvm/versions/node/v6.2.2/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
