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.
- -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
- 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
- -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
- -c CONFIG_FILE
- Read configuration from CONFIG_FILE, instead of the default.
- -h, --help
- Print a list of options and exit.
rifle shares configuration files with ranger, though ranger is not required in
order to use rifle. The default configuration file rifle.conf
expected to be at ~/.config/ranger/rifle.conf
. However, this can be
overridden with the -c

- Determines which editor to use for editing files.

empty (in the default rifle.conf). If both are undefined or empty,
"vim" is used instead.
- Determines which pager to use for displaying files (in the default
- 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.

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
Run it by picking the method 2, which calls 'python -- "$1"':
$ rifle -p 2 helloworld.py
Display the file in a pager inside a new terminal, run as root:
$ rifle -p 1 -f tr helloworld.py
