Also,

you should have seen 'n' ( n is quite large here ) posts with the following format

Code:

problem definition
sample input
sample output
what they had tried
problem faced

You could follow at least 3 out of that

What they are trying to say is that sed -e foo | sed -e bar can in many cases be modified into a single script sed -e foo -e bar and sometimes this can bring significant savings. But this is not always possible; it depends on what foo and bar do.

25 minutes sounds like you have an inefficient regular expression or loop in the script, but like others have stated here repeatedly, it's hard to say anything concrete until you post the actual code here.

Since this was more than a day ago, I guess the urgency waned.

ya the issue is no more urgent....

I worked my way around using sed..
Thanks!!
