Questions about Mac terminal custom commands and Mysql command

Mac Terminal Custom Commands

When entering the mac terminal, we often encounter some commands that are very complicated, and each time we need to enter more commands to achieve the effect, so there is a custom command function in the mac computer
Enter the mac terminalEnter:

vim ~/.bashrc After entering the interface, we can set custom commands.
First, you can press i to enter the editing mode. The custom command has a standard format which is
alias self-defined command = "input those commands before replacing"
For example, the way to enter the mysql database is rather cumbersome.Need /urs/loacl/mysql/bin/mysql -uroot -p to enter the database, so we can modify it to
alias gomysql = "urs/loacl/mysql/bin/mysql" After that we have to press esc to exit the editing, and thenPress: colon and wq to complete the editing and exit: wq
After exiting, use the command source ~/.bashrc to import the command just now, so that we can enter in the terminal:
gomysql -u root -p and then enter youYou can just get the password, isn't it very convenient?

About the permanent effect of custom commands on Mac terminal

For Mac custom commands to take effect, you must enter the terminal and enter the command: source ~/.bashrc to successfully introduce custom commands. Is there a way to make it permanent without entering the source command??The answer is yes.One file we are going to introduce is the bash.profile file that must be executed by the Mac to start the terminal.So we have to start editing it, just write the source command into this file, see the code for details

The terminal input: vim ~/.bash.profile to enter, the problem to pay attention to here, Mac will let you choose how to open this file
Select E to edit the file, if the default is read-only mode, you cannot write commands to this file, so pay special attention to this.
Enter the file and press i to edit, enter source ~/.bashrc and press esc to exit editing, then press :wq to complete editing and exit, just like this, you will find that after closing the terminal and restarting, you can use it without entering the source command.gomysql -uroot -p has entered the database
