HP-UX System Administrator's Guide: Configuration Management

Regardless of how you set up the manpages, you can recover disk space by removing
the nroff source files.
CAUTION: Before removing any files, make a backup of the man directories you
created in case you need to restore any files.
For example, to remove files for section 1 in /usr/share/man, enter:
# rm man1/*
# rm man1.Z/*
This concept for recovering disk space also applies to localized manpages. For further
details, see man(1) and catman(1M).
