   Siril GUI
    siril <file>             Start Siril with file.

   Siril CLI
    siril-cli  [-i  conf_file]  [-f] [-v] [-h] [-p] [-d working_directory]
   [-s script_file] [image_file_to_open]


Siril is an image processing tool specially tailored for noise reduction and improving the signal/noise ratio of an image from multiple captures, as required in astronomy. Siril can align, stack and enhance pictures from various file formats, even image sequences (movies and SER files). It makes use of OpenMP, supports all the cameras supported by libraw, and carries out its calculations in a high precision 32-bit floating point engine.


   -i     Starts Siril with configuration file  which  path  is  given  in

   -f     (or  --format) Prints all supported image input formats, depend‐
          ing on the libraries detected at compile-time

   -v     (or --version) Prints program name and version and exits

   -h     (or --help) Short usage help

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

   -d     (or --directory) Setting argument in cwd

   -s     (or  --script) Starts Siril without the graphical user interface
          and run a 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.

          The stylesheet used to change colours of the graphical user  in‐
          terface. This is useful for personalisation or if a GTK theme is
          incompatible with some coloured elements of Siril.
