NAME

       rifle - ranger's file opener

SYNOPSIS

       rifle [--help] [-f FLAGS] [-l] [-p KEYWORD] [-w PROGRAM] files

DESCRIPTION

       rifle is a powerful file executor that allows for complex file type checking, written to meet the needs
       of the file manager ranger.  rifle's strength lies in automatically determining file types, depending on
       which programs are installed on the system, even without any user interaction.

OPTIONS

       -f FLAGS      Specify  flags  for  opening  the files.  Flags are letters that changes how the program is
                     executed.  Any combination of flags will work.  Writing uppercase  flags  will  negate  the
                     effect of all previously used lowercase flags of the same letter.

                     Table of all flags:
                      f   fork program to background
                      r   run program as root, using sudo
                      t   run program in a separate terminal, as specified by $TERMCMD

       -l            List  all possible ways to open the specified files.  Each line will contain information in
                     the format of  id:label:flags:command.  id  is  the  identification  number.  label  is  an
                     arbitrary  string that was specified for this command, flags are the flags that are used by
                     default, and command is the command that is going to be executed.

       -p KEYWORD    Pick a method to open the files.

                     KEYWORD is either the ID number listed by "rifle -l" or a string that matches  a  label  in
                     the configuration file.

       -w PROGRAM    Open the files with the program PROGRAM

       -h, --help    Print a list of options and exit.

FILES

       rifle  shares  configuration files with ranger, though ranger is not required in order to use rifle.  The
       configuration file rifle.conf is expected to be at ~/.config/ranger/rifle.conf.

       This file specifies patterns for determining the commands to open files with.  The syntax is described in
       the comments of the default rifle.conf that ships with ranger.  To obtain it, you need  to  run:  "ranger
       --copy-config=rifle"

ENVIRONMENT

       EDITOR  Determines which editor to use for editing files (in the default rifle.conf).

       PAGER   Determines which pager to use for displaying files (in the default rifle.conf).

       TERMCMD Determines  the terminal emulator command for use with the t flag.  It is required that the value
               is the path to an executable file which accepts the "-e COMMAND" argument.

       XDG_CONFIG_HOME
               Specifies the directory for configuration files. Defaults to $HOME/.config.

EXAMPLES

       List all the different methods:

        $ rifle -l helloworld.py
        0:editor::"$EDITOR" -- "$@"
        1:pager::"$PAGER" -- "$@"
        2:::python -- "$1"

       Display its content by opening it with "cat":

        $ rifle -w cat helloworld.py
        print("Hello World!")

       Run it by picking the method 2, which calls 'python -- "$1"':

        $ rifle -p 2 helloworld.py
        Hello World!

       Display the file in a pager inside a new terminal, run as root:

        $ rifle -p 1 -f tr helloworld.py
