Shell Programming and Scripting

Good morning,

Can someone help to color a figure in columns if its exceeding a threshold using shell script .

ex. I have file contains 5 columns showing a value in % I need to show the value in red if it exceed 90 %

Appreciate your help

Using ANSI color, to display on your terminal.

Code:

awk '{for(i=1;i<=NF;i++)if ($i > 90)printf("%s ","\033[31m"$i"\033[0m");else printf("%s ",$i);printf "\n"}' filename

cheers,

Thanx for your reply.... But it dose not work .. It seems that it copy the strings of the color to the figure ... I have change the threshold from 90 to 20 just for test..
awk '{for(i=1;i<=NF;i++)if ($i >= 20)printf("%s "," \033[31m"$i"\033[0m");else printf("%s ",$i);printf "\n"}' test_mai
