       Siril CLI

       [image_file_to_open]

DESCRIPTION

       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.

OPTIONS

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

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

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

       -c     (or --copyright) Prints copyright 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 information. On POSIX systems, the  named  pipes
              are created in /tmp/siril_commands.in 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.

       image_file_to_open
              Open an image or sequence file right after start-up

FILES

       ~/.config/siril/siril.cfg
              User preferences. Overridden by the -i option.
       ~/.siril/siril.css
              The  style  sheet  used  to  change colors of the graphical user interface. This is
              useful for customization or if a  GTK  theme  is  incompatible  with  some  colored
              elements of Siril.
