apps.Application

apps.ClientApplication

apps.List

public class List
extends ClientApplication

Lists files and directories.

This application lists the remote files or directories named by its arguments. For each file, it lists the filename. For each directory, it lists the contents of the directory. Running the application with no arguments is equivalent to listing the current directory on the current host - that is, to giving it the single argument :.

Unlike the usual ls command, this application is not capable of printing file permissions, owner, group, or modification, access, or creation times - because none of these are stored by the filesystem.

Lists a remote path.

This method is called for each command line argument.

Parameters:
