How to write a text file with color
提问by yhabib
I'm trying to write a text file with two colors depending on the output. I using the echo -ecommand as I would when printing with colors in the console, like this:
我正在尝试根据输出编写具有两种颜色的文本文件。我echo -e像在控制台中打印颜色一样使用命令，如下所示：
RETURNED=$?
if [ $RETURNED == 0 ]
then
echo -e "\e[1;32mffmpeg -t $DURACION -f x11grab -s $RESOLUCION -r ${FPS[j]} -b:v $BR -i :0.0 -y $NOMBRE\e[0m" >> file.txt
fi
The idea would be: If the command worked, then write a green line, else use red. However I'm not getting any colored line in the text file.
想法是：如果命令有效，则写一条绿线，否则使用红色。但是，我没有在文本文件中看到任何彩色线条。

Have you tried less -R file.txt? That should show you the colour (works for me at least).
你试过less -R file.txt吗？那应该显示颜色（至少对我有用）。
If you want colour coding which is supported by non-shell applications your best bet is probably to output HTML, for example:
如果您想要非 shell 应用程序支持的颜色编码，您最好的选择可能是输出 HTML，例如：
printf '<code style="color: %s;">%s</code>' "green" "ffmpeg -t $DURACION -f x11grab -s $RESOLUCION -r ${FPS[j]} -b:v $BR -i :0.0 -y $NOMBRE" >> file.html

Try printfinstead of echo -e- the latter doesn't seem to work on all platforms (at least not on OSX) with ANSI escape sequences.
尝试printf而不是echo -e- 后者似乎不适用于具有 ANSI 转义序列的所有平台（至少不适用于 OSX）。
printf "\e[1;32mffmpeg -t $DURACION -f x11grab -s $RESOLUCION -r ${FPS[j]}\
-b:v $BR -i :0.0 -y $NOMBRE\n\e[0m" >> file.txt
Note the the \nto print a newline before the closing escape sequence.
请注意在\n结束转义序列之前打印换行符。
