Shell output color and flicker control

Shell Color and Flicker control

Sometimes custom output is required under the shell, such as adding color to the output, highlighting it, or adding flicker.
Then these color codes or control codes are relatively bad to remember. At this point we can consider the final desired result as a corresponding function,
It's much easier to call functions directly when you're using them.

Format

echo -e "\033[字背景颜色;字体颜色m字符串\033[控制码"

Custom color functions

# # Blue to EchofunctionBlue(){Echo-e"\033[34m[$]\033[0m"}# # Green to EchofunctionGreen(){Echo-e"\033[32m[$]\033[0m"}# # Error to Warning with blinkfunctionBred(){Echo-e"\033[31m\033[01m\033[05m[$]\033[0m"}## Error to warning with blink function byellow () {echo-e  "\033[33m\033[01m\033[05m[$]\033[0m"}## Errorfunction bred () { Span class= "Hljs-keyword" >echo-e  "\033[31m\033[01m[$]\033[0m"} ## warningfunction byellow () {echo-e  "\ 033[33m\033[01m[$]\033[0m "}            

You can write these functions into a common shell script, and each time you write another script, call it in the following way.

source /root/bin/common

Or you can paste the above code directly into the currently written script.

Of course, the first way can be recommended. You don't have to copy and paste every time. can be directly source 调用
