Folks;
I'm writing this as a part of a script:
echo "col1 hdg|col2hdg|col3hdg|"

How can i make these fields shows in Bold text?

Try this command:
echo "one $(tput bold)two$(tput rmso) three"

Thanks a lot, but your answer is not clear on how can it be used

Not clear ???

Thats a direct command which you could readily use it.
Did you try that out in a terminal ?

Am not clear about your requirement.

So i should replace echo "col1 hdg|col2hdg|col3hdg|" with echo "one $(tput bold)two$(tput rmso) three".
Here's the example:
Mine is: echo " Date Viewer Editor"
should it be:

echo " Date$(tput bold) Viewer$(tput rmso) Editor"

Also why is the first one is bold & the second is rmso?

rmso - offbold

man tput

Thanks but it didn't work
