ls_hidden

• ls_hidden.sh

  Some bash functions and aliases to list hidden dot files and directories.

  Aliases ls. and ll. are created to functionally imitate the ls command and popular alias ll, respectively.

  Command line arguments are supported. All options available to the ls command apply, however the -a option does not list ALL items in a directory, but only those preceeded by a dot. Items not preceeded by a dot can be listed if specified manually as a command line argument.
