siril 1.2.6                                         May 2023                                            SIRIL(1)

Siril  is  a  powerful  image  processing  tool  designed  for  improving  the  signal-to-noise  ratio of
       astronomical images. It offers a wide range of tools for aligning, stacking, and  enhancing  images  from
       various  file  formats,  including  image  sequences.  It features a high-precision 32-bit floating-point
       engine and supports parallel processing to run quickly.
       The application is divided into 2 binaries. The first one, siril, launches the program in  graphic  mode.
       The second one, siril-cli, is a command line interface allowing to execute the following options.

~/.config/siril/config.ini
              User preferences that can be overridden by the -i option.

       /usr/share/siril/siril.css
              The style sheet used to change the look of the  graphical  user  interface.  This  is  useful  for
              customization or if a GTK theme is incompatible with some colored elements of Siril.

-v,--version
              Prints the program name and version, then exits.

       -iconf_file
              Starts Siril with the specified configuration file.

       -f,--format
              Prints all supported input image formats, depending on the libraries detected at compile-time.

       -c,--copyright
              Prints copyright information, then exits.

       -h,--help
              Displays a brief usage summary.

       -p     Starts  Siril  without  the  graphical  user interface and uses named pipes to accept commands and
              print  logs  and  status  information.  On  POSIX  systems,  the  named  pipes  are   created   in
              /tmp/siril_commands.in and /tmp/siril_commands.out.

       -rinput_pipe_path, --inpipe=input_pipe_path
              Provides  an  alternative  path for the input pipe that receives the commands if -p is passed. The
              pipe can be created by an external program with the mkfifo(1) command.

       -woutput_pipe_path, --outpipe=output_pipe_path
              Provides an alternative path for the output pipe that prints logs and  status  updates  if  -p  is
              passed. The pipe can be created by an external program with the mkfifo(1) command.

       -dworking_directory, --directory=working_directory
              Sets the specified path as the current working directory.

       -sscript_file, --script=script_file
              Starts  Siril  without the graphical user interface and runs the specified script instead. Scripts
              are text files that contain a list of commands to be executed sequentially. In these files,  lines
              starting  with  a  #  are  considered as comments. If this option is not passed, pipe operation is
              assumed as if -p had been passed.

       -s-   Redirects inputs written after - to stdin.

       file   Opens the specified image or sequence file immediately after startup.
