I currently have a file that I'd like to pass through a _roff to format with underline a few words in the file, and then view the file in less. Just a few, mind you, not whole sections or anything.
How do i underline specific words in a file with _roff?
NB: I know I have groff and nroff.
NNB: I don't know a whole lot about type formatting.
At least with groff (I'm not sure it's portable), .ul gives you underline.
groff -Tascii <'<EOF'
This is a single line
.ul
with four underlined words
and more non-underline words.
EOF
If the only formatting you want is underlining, there may be an easier way. For example less automatically converts the sequence character-backspace-underscore (or underscore-backspace-character) to the underlined character; it also converts character-backspace-character to boldface.
echo $'one u\b_n\b_d\b_e\b_r\b_l\b_i\b_n\b_e\b_d\b_ word' | less
