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
