Linux-echo: print color output

Scripts may be used to generate a color escape sequences in the terminal text

Text color is determined by the corresponding color code as described. These include:

重置=0，黑色=30，红色=31，绿色=32，
黄色=33，蓝色=34，洋红=35，青色=36，白色=37。

To print color text, enter the following command:

echo -e "\e[1;31m This is red text \e[0m"

Note: wherein \ e [1; 31m is an escape character string, may be set to the color red, \ e [0m color set back again. 31 only need to replace the desired color code on it.

For a colored background, color codes are commonly used:

重置=0，黑色=40，红色=41，绿色=42，黄色=43，
蓝色=44，洋红=45，青色=46，白色=47。

* To set the background color, then enter the following command:

echo -e "\e[1;42m Green Background \e[0m"

Note: These examples contain a number of escape sequences. Man console_codes can use to view the document.
