Ranger Configuration

Config

Options 

# Which viewmode should be used?  Possible values are:
#     miller: Use miller columns which show multiple levels of the hierarchy
#     multipane: Midnight-commander like multipane view showing all tabs next
#                to each other
set viewmode miller
#set viewmode multipane

# Show hidden files? You can toggle this by typing 'zh'

# Ask for a confirmation when running the "delete" command?
# Valid values are "always", "never", "multiple" (default)
# With "multiple", ranger will ask only if you delete multiple files at once.

# Which script is used to generate file previews?
# ranger ships with scope.sh, a script that calls external programs (see

# Padding on the right when there's no preview?
# This allows you to click into the space to run the file.

# Save bookmarks (used with mX and `X) instantly?
# This helps to synchronize bookmarks between multiple ranger
# instances but leads to *slight* performance loss.
# When false, bookmarks are saved when ranger is exited.
set autosave_bookmarks false

# You can display the "real" cumulative size of directories by using the
# command :get_cumulative_size or typing "dc".  The size is expensive to
# calculate and will not be updated automatically.  You can choose
# to update it automatically though by turning on this option:

# The delay that ranger idly waits for user input, in milliseconds, with a

Rifle 

  # This is the configuration file of "rifle", ranger's file executor/opener.
  # Each line consists of conditions and a command.  For each line the conditions
  # are checked and if they are met, the respective command is run.
  #
  # Syntax:
  #   <condition1> , <condition2> , ... = command
  #
  # The command can contain these environment variables:
  #   $1-$9 | The n-th selected file
  #   $@    | All selected files
  #
  # If you use the special command "ask", rifle will ask you what program to run.
  #
  # Prefixing a condition with "!" will negate its result.
  # These conditions are currently supported:
  #   match <regexp> | The regexp matches $1
  #   ext <regexp>   | The regexp matches the extension of $1
  #   mime <regexp>  | The regexp matches the mime type of $1
  #   name <regexp>  | The regexp matches the basename of $1
  #   path <regexp>  | The regexp matches the absolute path of $1
  #   has <program>  | The program is installed (i.e. located in $PATH)
  #   env <variable> | The environment variable "variable" is non-empty
  #   file           | $1 is a file
  #   directory      | $1 is a directory
  #   number <n>     | change the number of this command to n
  #   terminal       | stdin, stderr and stdout are connected to a terminal
  #   X              | $DISPLAY is not empty (i.e. Xorg runs)
  #
  # There are also pseudo-conditions which have a "side effect":
  #   flag <flags>  | Change how the program is run. See below.
  #   label <label> | Assign a label or name to the command so it can
  #                 | be started with :open_with <label> in ranger
  #                 | or `rifle -p <label>` in the standalone executable.
  #   else          | Always true.
  #
  # Flags are single characters which slightly transform the command:
  #   f | Fork the program, make it run in the background.
  #     |   New command = setsid $command >& /dev/null &
  #   r | Execute the command with root permissions
  #     |   New command = sudo $command
  #   t | Run the program in a new terminal.  If $TERMCMD is not defined,
  #     | rifle will attempt to extract it from $TERM.
  #     |   New command = $TERMCMD -e $command
  # Note: The "New command" serves only as an illustration, the exact
  # implementation may differ.
  # Note: When using rifle in ranger, there is an additional flag "c" for
  # only running the current file even if you have marked multiple files.
