Color Linux命令输出

norm="$(printf '\033[0m')" #returns to "normal"
bold="$(printf '\033[0;1m')" #set bold
red="$(printf '\033[0;31m')" #set red
boldred="$(printf '\033[0;1;31m')" #set bold, and set red.

somecommand | sed -e "s/someregexp/${boldred}&${norm}/g"  # will color any occurence of someregexp in Bold red

printf "%s" "$red" ; locate something ; printf "%s" "$norm"  # will color output of locate something in red
   #I (ab)use printf "%s" "something", as it's more portable than echo,and easy to modify

还有很多其他的方法(创建一个函数/脚本,可以上色一个正则表达式,例如,然后: somecommand | colorize -c green 'foo.*bar' 'other')

您可以使用转义序列将任何输出的字体颜色更改为bash shell.以下是您需要的一些颜色代码:

BLACK="\033[30m"
RED="\033[31m"
GREEN="\033[32m"
YELLOW="\033[33m"
BLUE="\033[34m"
PINK="\033[35m"
CYAN="\033[36m"
WHITE="\033[37m"
NORMAL="\033[0;39m"

一旦定义了这些,就可以在普通的echo命令中使用它们.例如:

echo -e $GREEN this text is green $NORMAL and this is normal

请注意,-e并不总是必需的,但在某些操作系统(包括osx)上需要启用转义序列.

根据这些定义,您可以构建脚本和管道,以便为其他命令的输出着色.这是我用来为以下输出着色的完整示例svn up:

#!/bin/bash

BLACK="\033[30m"
RED="\033[31m"
GREEN="\033[32m"
YELLOW="\033[33m"
BLUE="\033[34m"
PINK="\033[35m"
CYAN="\033[36m"
WHITE="\033[37m"
NORMAL="\033[0;39m"

TMPFILE=.cvsup.tmp

svn up > $TMPFILE
svn status >> $TMPFILE
printf $YELLOW
grep -e ^"\? " -e ^"I " $TMPFILE
printf $GREEN
grep -e ^"R " -e ^"U " -e ^"G " $TMPFILE
printf $BLUE
grep -e ^"M " -e ^"E " $TMPFILE
printf $RED
grep -e ^"C " -e ^"! " -e ^"X " -e ^"~ " $TMPFILE
printf $PINK
grep ^"R " $TMPFILE
printf $PINK
grep ^"D " $TMPFILE
printf $CYAN
grep ^"A " $TMPFILE

printf $NORMAL
rm $TMPFILE
