I can't really take credit for this as it came straight from the Unix Guru Universe Tip of the Day (subscribe). To save a copy of any man page to text simply type:
man command_name | col -b > output_file_nameFor example:
man grep | col -b > grep.txtThis can be especially useful for larger man pages (tcsh, for example), as you can now open and work with the text file in any GUI text editor.
