Column 1 is the start region of underline the text in column 3;
Column 2 is the end region of underline the text in column 3;
Do anybody experience underline text in unix by command line?
I'm plan to underline the region in column 3 based on the info shown in column 1 and 2.

Thanks.

Plain text files do not have underlined regions.You can have that in either formatable text, e.g. html, rtf, or on screen / terminal. What do you want?

Question: Do you want this to work on many terminals, or just yours?

Underline is a fairly odd attribute which may not work the same way on all terminals, if they support it at all. Changing the color has more broad support.

And if you want to store this in a text file, you probably shouldn't be using terminal color/format attributes at all. Text is text.

Hi Corona688,

I work on terminal right now.
My OS is ubuntu.
I have a normal *.txt file which I need to underline all the column 3 region based on column 1 and column 2 info.
I just wondering how to use command line to "highlight" all those interested region in a one run instead of one by one manual check and edit it.

If underline is difficult to archive, either highlight with color, bold or italic those specific region should be fine too.

Thanks a lot.

When editing that file manually, what do you modify/insert to achive underline?

Hi RudiC,

What I did was I open the *.txt through Microsoft Excel.
After then I underline or italic the region of column 3 based on column 1 and column 2 information.
But it is a bit tedious if I wanna to edit a long list of data

Do you have any idea or advice?
My main purpose was just wanna to automatic "highlight" those region based on column 1 and column 2 info.
It can be bold or italic those region.
As long as it look "special" from normal word.

cpp_beginner,
If you will be importing the text file into Excel, one solution would be to write an Excel formula or some VBA code to handle the underlining part.
