Thus, ls -lrt will give a long listing, oldest first, which is handy for seeing which files in a large directory have recently been changed. ls -r lists the files in the reverse of the order that they would otherwise have been listed in.ls -t lists the files in order of the time when they were last modified (newest first) rather than in alphabetical order.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.If you want files to be properly hidden, you will have to change folder permissions using chmod. anyone will still be able to see it using. Unless you are working together on the same file, you need not worry about Unix groups. The command DIR /b will return just a list of filenames, when displaying subfolders with DIR /b /s the command will return a full pathname. Files starting with a dot are by default hidden. 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.
