样品
#！ /jjdmla/bash
orgColor=`echo -e ' 33[0m ' `
redColor=`echo -e ' 33[31m ' `
echo 'an original font line '
echo ' $ { red color } aredfontline $ { org color } '
echo 'an original font line another '
方法使用tput命令设置文字的前景颜色和背景颜色
#！ /jjdmla/bash
orgColor=`tput setaf 7`
redColor=`tput setaf 1`
echo 'an original font line '
echo ' $ { red color } aredfontline $ { org color } '
echo 'an original font line another '
方法设置字符编码设置字符的前景颜色和背景颜色
一.如何在外壳上实现
只需设置输出属性，即可输出彩色文本。 shell的某些属性：
33[0m关闭所有属性]
(033 )设定1m高亮度
33[4m下划线]
(033 )闪烁5米
(033 ) 7m翻转
(033 ) 8m消隐
(033 ) 30m至(33 ) 37m设置前景色
从(033 ) 40m到(33 ) 47m设定背景色
33[nA光标向上移动n行
33[nB光标下移n行
33[nC将数控光标向右移动n行
33[nD将nd光标向左移动n行
( 33[y； 设定xH光标位置
(033 ) 2j清晰屏幕
33[K清除k光标到行尾的内容
33[s保存s光标位置
33[u撤消u光标位置]
( 33[？ 25l隐藏光标
( 33[？ 25h显示光标
------------- -请参阅
各数字表示的颜色如下。
字背景颜色范围：40----49
40:黑色
41:深红
42:绿色
43:黄色
44:蓝色
45:紫色
46:深绿色
47:白色
字的颜色：30----39
30:黑色
31:红色
32:绿色
33:黄
34:蓝色
35:紫色
36:深绿色
37:白色
示例： echo -e ' 33[34mHello，world！] (-e的作用是指导您设置输出属性。
恢复属性是默认值。 echo -e ' 33[0m '，
可以组合同类的多个设定项目，中间用分号()分隔。 如下所示。
echo -e ' 33[20； 1h(033 ) 1； 4； 34mHello，world(033[0m
二、用c语言实现方法
和壳牌的方法相似。 示例：
int color=34；
printf((((033 ) 20； 1h(033 ) 1； 4； %dmHello，world. 33[0m '，color；
三.如何在Python上实现
color=34
print “ 33[20； 1h(033 ) 1； 4； %dHello，world. 33[0m'%color

使用
专用
tput sub-commands are discussed later.Direct
Call tput as part of a sequence of commands:
tput setaf1;echo"this is red text"
Use ; instead of && so if tput errors the text still shows.
Shell variables
Another option is to use shell variables:
red=`tput setaf 1`green=`tput setaf 2`reset=`tput sgr0`echo"${red}red text ${green}green text${reset}"
tput produces character sequences that are interpreted by the terminal as having a special meaning. They will not be shown themselves. Note that they can still be saved into files or processed as input by programs other than the terminal.
Command substitution
It may be more convenient to insert tput's output directly into your echo strings using command substitution:
echo"$(tput setaf 1)Red text $(tput setab 7)and white background$(tput sgr 0)"
Example
The above command produces this on Ubuntu:
Foreground & background colour commands
tput setab[1-7]# Set the background colour using ANSI escapetput setaf[1-7]# Set the foreground colour using ANSI escape
Colours are as follows:
Num Colour #define R G B 0 black COLOR_BLACK 0,0,0 1 red COLOR_RED 1,0,0 2 green COLOR_GREEN 0,1,0 3 yellow COLOR_YELLOW 1,1,0 4 blue COLOR_BLUE 0,0,1 5 magenta COLOR_MAGENTA 1,0,1 6 cyan COLOR_CYAN 0,1,1 7 white COLOR_WHITE 1,1,1
There are also non-ANSI versions of the colour setting functions (setb instead of setab, and setfinstead of setaf) which use different numbers, not given here.
Text mode commands
tput bold# Select bold modetput dim# Select dim (half-bright) modetput smul# Enable underline modetput rmul# Disable underline modetput rev# Turn on reverse video modetput smso# Enter standout (bold) modetput rmso# Exit standout mode
Cursor movement commands
tput cup Y X# Move cursor to screen postion X,Y (top left is 0,0)tput cuf N# Move N characters forward (right)tput cub N# Move N characters back (left)tput cuu N# Move N lines uptput ll# Move to last line, first column (if no cup)tput sc# Save the cursor positiontput rc# Restore the cursor positiontput lines# Output the number of lines of the terminaltput cols# Output the number of columns of the terminal
Clear and insert commands
tput ech N# Erase N characterstput clear# Clear screen and move the cursor to 0,0tput el1# Clear to beginning of linetput el# Clear to end of linetput ed# Clear to end of screentput ich N# Insert N characters (moves rest of line forward!)tput il N# Insert N lines
Other commands
tput sgr0# Reset text format to the terminal's defaulttput bel# Play a bell
With compiz wobbly windows, the bel command makes the terminal wobble for a second to draw the user's attention.
Scripts
tput accepts scripts containing one command per line, which are executed in order before tputexits.
Avoid temporary files by echoing a multiline string and piping it:
echo-e"setf 7nsetb 1"|tput-S# set fg white and bg red
See also
See man 5 terminfo for the complete list of commands and more details on these options. (The corresponding tput command is listed in the Cap-name column of the huge table that starts at line 81.)
