How to put one word in parenthesis with sed and a regex?-CodePudding

I would like to put one word in parenthesis with sed and a regex but I don't know how to do it.

I think the command shoud look a little bit like this :

sed -r "s/???/\(&\)/g"

but I don't know know how to match a word without whitespaces...

If I try on this example :

WORD
abc = WORD

I get :

(WORD)
(abc = WORD)

What I want is :

(WORD)
abc = (WORD)

CodePudding user response：

Using sed, you can match capitalized characters

$ sed 's/[[:upper:]]\ /(&)/' input_file
(WORD)
abc = (WORD)

or the last alphabetic characters at the end of the line

$ sed 's/[[:alpha:]]\ $/(&)/' input_file
(WORD)
abc = (WORD)

I found what I was looking for :

sed -r "s/\S /\(&\)/g""

It was quite simple actually.
