A book that I've had success with is: UNIX Shells, by Ellie Quigley. It has some typos in it but it's rather good.

fixman(1M) fixman(1M)
NAME
fixman - fix manpages for faster viewing with man command
SYNOPSIS
alt-path]
DESCRIPTION
The command is a shell script that processes manpages in the directories to unexpand spaces to tabs where possible, and to remove all char-
acter-backspace pairs (which usually exist to cause overstriking or underscoring for printer output). Removal of unnecessary character
sequences improves the speed of man(1), and reduces disk space consumption. The command should be run after using to create formatted,
manpages from unformatted, source files (see catman(1M)).
By default, searches for subdirectories in the following parent directories in the order indicated:
o
o
o
If the environment variable is set, the directory paths specified by are searched instead of the default. See environ(5) for a description
of the environment variable.
The command does not remove duplicate blank lines. Thus, all files remain a multiple of one page (66 lines) long and can still be passed
directly to (see lp(1)). (Note that man(1) normally uses to accomplish this removal.)
To ensure success, should be run by a user who has appropriate privileges. It will take awhile to complete depending on system speed,
load, memory size, etc. As a side-effect, file ownerships and permissions may be changed.
Options
Perform actions based on the given alternate root.
With this option, alt-path will be prepended to all directory paths, including default paths or the paths defined by
EXTERNAL INFLUENCES
Environment Variables
if set, defines the directories to be searched for manpages.
WARNINGS
If the value of is not the same while is running as it was when was run or when manpage files were installed, some files may be missed and
not processed (see catman(1M)).
EXAMPLES
Run fixman from a server to fix the manpages on a diskless under the alternate root
This will fix manpages in directories under:
FILES
Directories containing [compressed]
nroff(1)-formatted versions of manpages
