Shell output function with color text

Some monitoring scripts or restart services. The failure is successfully output in red or green. A function is used to encapsulate this function. Function: receives string parameters, changes the OK in the received parameter [] to red, and the FAILD to green. For example, "success": "failure": Put the Code directly #! /Bin/bashaction () {MSG = $1 COLOER = 'echo $1

Some monitoring scripts or restart services. The failure is successfully output in red or green.

A function is used to encapsulate this function.

Function: receives string parameters, changes the OK in the received parameter [] to red, and the FAILD to green. For example:

Successful:

#!/bin/bashaction(){MSG=$1COLOER=`echo $1|sed 's#^.*\[\(.*\)\].*#\1#g'`BASE=`echo $1|sed 's#\(^.*\)\[.*]#\1#g'`if[ "OK"!= "$COLOER"];thenecho -e "${BASE} [\e[0;31;1m  $COLOER  \e[0m]"elseecho -e "${BASE} [\e[1;32m $COLOER \e[0m]"fi}STAT=`curl -I -s 1www.baidu.com|grep HTTP|awk '{print $2}'`[ -z $STAT ]&&STAT=500if[ "200"-eq "$STAT"];thenaction "THE WEB STATUS IS  ............ [OK]"exit 0elseaction "THE WEB STATUS IS  ............ [FAILD]"exit 1fi

You can optimize the above action function and encode the color information as a parameter. More convenient call.

For example, action "blue" "the web status is [OK]". If you do not have this requirement, you will not write it.

Okay, it's idle, So I optimized the action function.

Only the green and red colors are encoded. Action "green" "the web status is [OK]", called in this way.

Code:

action(){REG_RED="\e[0;31;1m"REG_GREEN="\e[1;32m"RES="\e[0m"COLOER=""case"$1"inred|RED)COLOER=$REG_RED;;green|GREEN)COLOER=$REG_GREEN;;esacCOLOERTEXT=`echo $2|sed 's#^.*\[\(.*\)\].*#\1#g'`BASE=`echo $2|sed 's#\(^.*\)\[.*]#\1#g'`if[ "OK"!= "$COLOERTEXT"];thenecho -e "${BASE} [${COLOER} $COLOERTEXT ${RES}]"elseecho -e "${BASE} [${COLOER} $COLOERTEXT ${RES}]"fi}

The following is a color encoding list!

1. The red font abc is output, and the background color remains unchanged. The following three effects are the same:
Echo-e '\ 033 [0; 31; 1 m abc \ 033 [0m'
Echo-e "\ e [1; 31 m abc \ e [0 m"
Echo-e "\ e [0; 31; 1 m abc \ e [0 m"

2. The yellow font abc and red background color are displayed. The following three effects are the same:
Echo-e '\ 033 [41; 33; 1 m abc \ 033 [0m'
Echo-e "\ e [41; 33 m abc \ e [0 m"
Echo-e "\ e [41; 33; 1 m abc \ e [0 m"

30 Black 31 red, 32 green, 33 yellow, 34 blue, 35 purple, 36 green, 37 white (Gray)
Echo-e "\ e [1; 30 m skyapp exist \ e [0 m" // black
Echo-e "\ e [1; 31 m skyapp exist \ e [0 m" // red
Echo-e "\ e [1; 32 m skyapp exist \ e [0 m" // green
Echo-e "\ e [1; 33 m skyapp exist \ e [0 m" // yellow
Echo-e "\ e [1; 34 m skyapp exist \ e [0 m" // blue
Echo-e "\ e [1; 35 m skyapp exist \ e [0 m" // purple
Echo-e "\ e [1; 36 m skyapp exist \ e [0 m" // green
Echo-e "\ e [1; 37 m skyapp exist \ e [0 m" // white (Gray)
