ls -R gives a recursive listing, including the contents of all subdirectories and their subdirectories and so on.

The last column is the name of the file.

The next three columns are the time at which the file was last changed (for a directory, this is the time at which a file in that directory was last created or deleted).

The fifth column is the size of the file in bytes.

Unless you are working together on the same file, you need not worry about Unix groups.

The third and fourth columns are the user who owns the file and the Unix group of users to which the file belongs.

Generally an ordinary file will only have one link, but a directory will have more, because you can refer to it as ``dirname'', ``dirname/.'' where the dot means ``current directory'', and if it has a subdirectory named ``subdir'', ``dirname/subdir/.'' (the ``.'' means ``parent directory'').

The second column is the number of links to the file i.e., (more or less) the number of names there are for the file.

The first column gives the type of the file ( e.g., directory or ordinary file) and the file permissions.

ls -l gives a long listing of all files.

ls -F gives a full listing, indicating what type files are by putting a slash after directories and a star after executable files (programs you can run).ls -a will list all files including hidden files (files with names beginning with a dot).

Options can be combined (this is a general principle of Unix commands) - for example 'ls -la' gives a long listing of all files. There are a large number of options here are some of the most useful. 'ls *.tex' lists only those files ending in '.tex'. 'ls' on its own lists all files in the current directory except for hidden files.
