Tutorial on setting prompt implementation information prompt in MySQL

Then let's see what it looks like by default.

Let's see what it looks like after using the prompt parameter.

Then let's look at how black technology works.

Now let's talk about the last color display method. By default, after the -- prompt parameter is used, the color is not displayed. To display the color, we need to use the system function,

Root@GCE-Node1_www.dwhd.org ~ # Awk '/mariadb /'. bashrc alias mysql = $ (echo-e '/usr/local/mariadb-galera/bin/mysql-uroot-p *****-h127.0.0.1-S/tmp/mysql. sock-D mysql -- prompt = "\ x1B [31m \ u \ x1B [34m @ \ x1B [0 m [\ D]: \ x1B [32mGCE-Node1_www.dwhd.org \ x1B [0 m: \ x1B [31 m (\ d) \ x1B [36m \ x1B [0 m> "') [root@GCE-Node1_www.dwhd.org ~] # Alias mysql = $ (echo-e '/usr/local/mariadb-galera/bin/mysql-uroot-p *****-h127.0.0.1-S/tmp/mysql. sock-D mysql -- prompt = "\ x1B [31m \ u \ x1B [34m @ \ x1B [0 m [\ D]: \ x1B [32mGCE-Node1_www.dwhd.org \ x1B [0 m: \ x1B [31 m (\ d) \ x1B [0 m> "')

 

Splitting description

Alias mysql = $ () # set the alias echo-e '/usr/local/mariadb-galera/bin/mysql-uroot-p *******-h127.0.0.1-S/tmp/mysql. sock-D mysql -- prompt = "\ x1B [31m \ u \ x1B [34m @ \ x1B [0 m [\ D]: \ x1B [32mGCE-Node1_www.dwhd.org \ x1B [0 m: \ x1B [31 m (\ d) \ x1B [0 m> "'# set the mysql command to the specified content -- prompt =" \ x1B [31m \ u \ x1B [34m @ \ x1B [0 m [\ D]: \ x1B [32mgce-node.pdf www.dwhd.org \ x1B [0 m: \ x1B [31 m (\ d) \ x1B [0 m> "# as shown in the preceding split, the specified \ u is red, the specified @ is blue, and the specified [\ D] is white, Specify the GCE-Node1_www.dwhd.org to green, specify: white, specify (\ d) to red, specify> to white. # You can find the specific code from Google. I will not elaborate on it here.

 

Thought this would end? Take a look at the following. The execution result is also displayed in color.
