Hi all

I have a file contains columns showing figures as below :

Input file

A B C
D 50 60 90
E 100 20 53
F 30 40 70
G 25 27 45

I want to color the value above or equal 90 by red and to be shown as below
output file
A B C
D 50 60 90
E 100 20 53
F 30 40 70
G 25 27 45

I have used awk command but i fail to get it works

awk '{for(i=2;i<=NF;i++) if ($i >= 90) printf ("%s ","\033[31m"$i"\033[0m");else printf("%s ",$i);printf "\n"}' inputfile

can anybody help me with this...Thanx

The same working fine for me ..
check any system related settings related to color.

I have got the below output
Note: I have changed 90 by 20 for test only

\033[31m38\033[0m 19 \033[31m37\033[0m
\033[31m31\033[0m \033[31m32\033[0m 12
\033[31m30\033[0m 19 \033[31m35\033[0m
\033[31m27\033[0m \033[31m23\033[0m \033[31m21\033[0m
\033[31m21\033[0m \033[31m27\033[0m \033[31m24\033[0m
\033[31m24\033[0m \033[31m20\033[0m \033[31m24\033[0m
\033[31m30\033[0m \033[31m25\033[0m \033[31m21\033[0m
\033[31m27\033[0m 18 \033[31m22\033[0m

\033[31m24\033[0m \033[31m23\033[0m \033[31m21\033[0m
\033[31m31\033[0m \033[31m20\033[0m \033[31m26\033[0m

Any idea...

Thats ANSI color sequence. What terminal do you use to connect to the UNIX BOX? Does it support ANSI..
You may want to use some other terminal to do that - eg putty

Dear devaraj
Thanx.. I test the coloring in my terminal & its working but i think the problem is some how with awk option as it prints color string
Instead of showing the color on selected value..

What do you think ?

Thanx everyone for your contrbution..
I tried the command with another server and it works perfect..

Any one has an idea what could be the reason that command not working in my first unix box..
Is there anything that i can check in advance?

Appreciated
