Navigating directories with * / . and ..

I would be very happy (after a lot of fruitless searching) if someone could explain the meaning of these variations on the ls command:

ls */
ls */.
ls */./

I understand the basic use of ls already eg ls -al but am wanting to list from different points in the file structure without having to leave the directory I am in and my experimenting has left me confused.

Also in the examples above what is the correct term for the characters after the "ls"? Are they correctly called operators? Or is that the wrong term?

Thanks.

MAKEWHATIS(1)						    BSD General Commands Manual 					     MAKEWHATIS(1)

NAME
makewhatis -- create whatis database SYNOPSIS
makewhatis [-a] [-i column] [-n name] [-o file] [-v] [-L] [directories ...] DESCRIPTION
The makewhatis utility collects the names and short descriptions from all the unformatted man pages in the directories and puts them into a file used by the whatis(1) and apropos(1) commands. Directories may be separated by colons instead of spaces. If no directories are speci- fied, the contents of the MANPATH environment variable will be used, or if that is not set, the default directory /usr/share/man will be pro- cessed. The options are as follows: -a Appends to the output file(s) instead of replacing them. The output will be sorted with duplicate lines removed, but may have obsolete entries. -i column Indents the description by column characters. The default value is 24. -n name Uses name instead of whatis. -o file Outputs all lines to the file instead of */man/whatis. -v Makes makewhatis more verbose about what it is doing. -L Process only localized subdirectories corresponding to the locale specified in the standard environment variables. ENVIRONMENT
LC_ALL, LC_CTYPE, LANG These variables control what subdirectories will be processed if the -L option is used. MACHINE If set, its value is used to override the current machine type when searching machine specific subdirectories. MACHINE_ARCH If set, its value is used to override the current architecture when searching architecture specific subdirectories. MANPATH Determines the set of directories to be processed if none are given on the command line. FILES
/usr/share/man Default directory to process if the MANPATH environment variable is not set. */man/whatis The default output file. EXIT STATUS
The makewhatis utility exits 0 on success, and >0 if an error occurs. SEE ALSO
apropos(1), whatis(1) HISTORY
The makewhatis command appeared in FreeBSD 2.1. AUTHORS
The makewhatis program was originally written in Perl and was contributed by Wolfram Schneider. The current version of makewhatis was rewritten in C by John Rochester. BSD
December 3, 2005 BSD
