Let the echo output in the shell script color

There are two ways to bring the echo output color

1. Define color variables in shell scripts, use ECHO-E to call variables
   

2. When defining a variable, define the ECHO-E in the variable, and then output the variable

Shell script that lets echo output display color

#!/bin/bash# defines the color of the variable red_color= ' \e[1;31m '    #红GREEN_COLOR = ' \e[1;32m '   #绿YELOW_COLOR = ' \e[1;33m '   #黄BLUE_COLOR = ' \e[1;34m '    #蓝PINK = ' \e[1;35m '        #粉红RES = ' \e[0m ' # Need to use echo -eecho -e   "${red_color}======red color======${res}" echo -e   "${yelow_color}======yelow color======${res}" echo -e   "${blue_color}======green color ======${res} "echo -e  " ${green_color}======green color======${res} "echo -e    "${pink}======pink color======${res}" echo  "################################################### ########## "#直接把echo  -e into the variable, the use of direct output variables can be setcolor_success=" echo -en \\033[1;32m "Setcolor_ Failure= "echo -en \\033[1;31m" setcolor_warning= "echo -en \\033[1;33m" SETCOLOR_NORMAL= "Echo  -en \\033[0;39m "echo ----oldboy trainning-----   &&  $ setcolor_successecho ----oldboy trainning-----   &&   $SETCOLOR _failureecho ----Oldboy  trainning-----   &&   $SETCOLOR _warningecho ----oldboy  Trainning-----   &&   $SETCOLOR _normal
