What operating system are you using? -LINUX
What shell are you using?- bash
What terminal type are you using?- bash
What color do you want to use? RED
Under what condition(s) do you want to use this alternative color? - Here below in coloumn YX, if any value is greaterthan 0, color to YELLOW
Code:
SS|GE|GE|XX|YX
AP|0|0|-1|0
CP|56|0|0|56
CP|0|0|-9|0

What have you tried to accomplish this goal on your own?
Data is available in mariadb, i m selecting data and writing to R.txt separated by | delimiter

I have written below normal printing as table,
Code:
<cat R.txt|awk -F'|' 'BEGIN {print "<!DOCTYPE html><html><body><table border="1" width=75% cellspacing=0> <tr><th bgcolor='"$BGC"'>.....</tr>"}{print "<tr>";
for(i=1;i<=NF;i++)
{
print "<td> "$i"</td>
} />

Is a <tab> character supposed to be the field delimiter in your file? | is the delimter
Why is there a <tab> and a <space> between the XX and YX in the header line in the first line of your output? yes this is header
Why are there a bunch of <space>s instead of a <tab> between the -9 and the 0 in the last line of your output? while copying, spaces been added.
Is your input file in the same format as your output file?input is .txt output i m expecting html and yes, the sequence is same.
Will the YX field always be in the 5th field of your input file? If not how are we supposed to find it? yes it is 5th field

Sure your code will produce a valid HTML file?


Try this modification to your sample:

Code:
awk -F'|' '
BEGIN   {print "<!DOCTYPE html><html><body><table border=\"1\" width=75% cellspacing=0><tr><th bgcolor=\"YELLOW\">.....</tr>"
         AC="style=\"color:red;\""
        }
        {print "<tr>"
         for(i=1;i<=NF;i++)     print "<td " ((i==5 && $i>0)?AC:"") "> "$i"</td>"
        print "</tr>"
        }
END     {print "</body></html>"
        }
' R.txt

Thank you Rudic, seems it is working, but it is not working if the value is comma separated.
<Eg:2,333,555> and it is working for <5.77>

So - what would your conclusion be? What if you have 5,333,444?

Of course it isn't. You said your input file was separated by | field delimiters; not by comma delimiters. That is why RudiC gave you code that started with:
Code:
awk -F'|'

If you're going to change the field delimiter, you have to change the field delimiter in the code that will be processing your new input file format too.

This is my value in that column 5,333,444.89, such values it is treating as negative, becoz when i use <0 condition such values are all getting changed to RED and one more when i use align="right" in same condition in td it is not working.

"it is not working" doesn't really help to analyse / debug, nor do moving targets. What do you think?

If you change the script / result and end up with it not working, it's not quite fair to blame the helpers in here. How about posting the entire new script and the entire new sample data?


The commas are "thousands separators", a concept unknown to awk. Those make the field a string, which, by default, should use all leading digits up to the first non-digit when evaluating the string. BTW, the script as given works for me: print in red if given the 5,333,444.89 in field 5.
