如何在bash shell中自动为程序输出着色? [英] How do you automatically colorize program outputs in a bash shell?

问题描述

我想使用任何输出到屏幕的程序，捕获输出，并在将某些关键字输出到屏幕之前为其着色.例如，这是正常程序的输出:

I want to take any program that outputs to the screen, catch the output, and colorize certain keywords before they are output to the screen. For example, here's the normal program output:

bash# <program>
blah blah blah       <-- this output has no color

vs.

bash# <program>
blah blah blah       <-- this output is colorful

理想情况下，程序是什么都没有关系.我只是在寻找一种将更多颜色融合到我的Konsole中的好方法.

Ideally it doesn't matter what the program is. I'm just looking for a good way to incorporate more color into my konsoles.

对不起，应该已经清楚了.我不只是在给shell脚本输出着色.

Sorry, should've been clear. I'm not trying to just colorize shell script outputs.

推荐答案

#!/bin/sh
redf=$(tput setaf 1)
redb=$(tput setab 1)
reset=$(tput op)
echo "${redf}red${reset} in front, ${redb}red${reset} in back"

有关终端功能的详细列表，请参见 terminfo .后缀为 -m 的 $ TERM (例如 ansi-m )表示屏幕为单色，但是只要颜色有效，以下字符串功能不能为空:

See terminfo for a long listing of terminal capabilities. A $TERM with suffix -m (e.g. ansi-m) means the screen is monochrome, but as long as color works, the following string capabilities should be non-empty:

       enter_bold_mode               bold         md        turn on bold (extra
                                                            bright) mode
       enter_italics_mode            sitm         ZH        Enter italic mode
       enter_reverse_mode            rev          mr        turn on reverse
                                                            video mode
       orig_pair                     op           op        Set default pair to
                                                            its original value
       set_a_background              setab        AB        Set background
                                                            color to #1, using
                                                            ANSI escape
       set_a_foreground              setaf        AF        Set foreground
                                                            color to #1, using
                                                            ANSI escape

颜色0-7几乎是标准颜色:黑色，红色，绿色，黄色，蓝色，洋红色，青色，白色.除此之外，可能不存在，或者可能更多.

Colors 0-7 are pretty much standard: black, red, green, yellow, blue, magenta, cyan, white. Beyond that may not exist or may be more variable.
