A simple script to view man pages in the terminal.

It uses wget and w3m (by default) to get the man pages from various websites.

man <command>        # view man page in plain text in $PAGER
man -H <command>     # view man page as HTML in $TERM_BROWSER
man <command> --url  # print the URL of the man page to STDOUT

Some of the GNU man options are supported:

  man <command>           # [get and] print the man page

  man <section> <command> # [get and] print the man page in given section

  man <command> --url     # print the URL from which the man
                          # page was/would be downloaded

  man --help              # print this help info

Where <command> is the command name you want to read about.

If needed, man will cycle through each category to find an existing man page.

To view man pages as HTML (using $TERM_BROWSER, or w3m if this variable doesn't exit), use -H as the first option.

Man pages are divided into sections, as follows:

1. User: most user commands and programs.
2. System: calls by the Linux kernel.
3. Library: documents provided by the standard C library.
4. Devices: documents various devices, most of which reside in /dev.
5. Files: describes various file formats and filesystems and proc(5).
6. Overviews, conventions, and miscellaneous.
7. Superuser and system administration commands.

  man mount               # view 'mount' command

  man intro.1             # view info about section 1

  man mount.8             # view 'mount' in section 8 (config stuff)

  man 8 mount             # same as above, but doesn't work with -H

  man 5 xorgconf          # get xorg.conf from section 5 (dont use . in name)

  man -H mount            # view 'mount' man page as HTML using $BROWSER

  man <command> --url     # only print the URL from which the man page
                          # was/would be downloaded

Uses these URLs from the following websites:

the Ubuntu or Debian man pages, also:

http://manpages.org/${command}/${section}
https://linux.die.net/man/${section}/${command}
https://www.mankier.com/${section}/${command}
http://man.he.net/?topic=${command}&section=${section}
https://man7.org/linux/man-pages/man${section}/${command}.${section}.html
http://manpages.org/${command}
http://man.he.net/?topic=${command}&section=all
https://ss64.com/bash/${command}.html

It downloads the man page from a website, using wget.

If running an Ubuntu based Puppy Linux, the correct version of Ubuntu man pages will be searched first. Likewise for any Debian based Puppy Linux, too.

It uses $HTMLPAGER to convert the HTML file to plain text, or w3m -dump if that variable doesn't exist.

It saves the man pages in plain text.

The plain text files are cleaned up a bit, and saved to $HOME/.w3m-man/<cmd>.<section>.

It then displays them using $MANPAGER or $PAGER, or falls back to less, if these aren't set.

Does not need roff, groff (etc) to be installed, or any man pages.

Note:

• $TERM_BROWSER could equal w3m or lynx.
• $HTMLPAGER could equal w3m -dump, or lynx -dump might work too.
