How can I force the man
command to not use a pager, and instead output the whole manpage at once and keep all highlighting?
If I use man -P cat
or man | cat
, I lose highlighting.

Long reading of manuals for man, less, groff and grotty finally gave me answer
Highlighting by default is made using backspace sequences: c\bc
=> bold c, _\bc
=> underlined c. But if output as is using cat as pager just outputs plain c in both cases. Also blank lines are squeezed, so to do all this, pager must be set to ul | cat -s
.
Pager can be set in many ways:
using MANPAGER or PAGER variables (MANPAGER is better as PAGER affects not only man command)
export MANPAGER='ul | cat -s'
in man.conf
PAGER ul | cat -s
using -P parameter
cat -P 'ul | cat -s' …
or
alias man='man -P "ul | cat -s"'
+1, but I only need to use 'ul' as my pager to dump the output to the console with highlighting. I.e. man -P ul <command>

man man
...
PAGER A program to use for interactively delivering
man's output to the screen. If not set,
`more -s' is used. See more(1).
Which means the pager is regulated by PAGER env. variable, Thus just define PAGER as
setenv PAGER cat
and enjoy.
Why the downvote? This may not be the optimal solution, but it's not incorrect. Try it: $ PAGER=cat man foobar

Isn't using cat
as a pager essentially the same thing as not using a pager at all? – bcat – 2009-12-24T21:46:20.170
The question is about not using a pager and this without loosing highlighting. – Pascal Thivent – 2009-12-24T21:47:29.880
When I try this approach, I lose highlighting (on Mac OS X and Ubuntu). – Brian Campbell – 2009-12-24T23:55:36.693
i also lose highlighting. as a comment in another answer points out, man -P ul
or PAGER=ul man
works. TIL about ul… – flying sheep – 2014-02-19T09:28:01.520

Alternatively, there's always the -P
switch:
man -P cat foo
I already sad that with -P cat
I use highlighting – tig – 2009-12-24T23:43:27.920
I checked my theory with <code>man -P cat man |tee foo.txt ; less -R foo.txt</code>. The formatting is still there; it just doesn't show up in the command window. – amphetamachine – 2010-01-04T22:55:25.333

This is not exactly what you want (you won't get the output in the console) but you could generate a dvi file with the content of a manual as explained in man's man:
man -l -Tdvi ./foo.1x.gz > ./foo.1x.dvi
This command will decompress and format the nroff source manual page ./foo.1x.gz into a device independent (dvi) file. The redi‐ rection is necessary as the -T flag causes output to be directed to stdout with no pager. The output could be viewed with a program such as xdvi or further processed into PostScript using a program such as dvips.
I've just tested this and opened the dvi file with evince: the highlighting is not lost.
man on mac has no -l and -T params – tig – 2009-12-24T23:46:34.573
