SIRIL(1)		    General Commands Manual		      SIRIL(1)

NAME
       siril - image processing	tool for astronomy and other applications

SYNOPSIS
       siril [options] [file]
       siril-cli [options] [file]

DESCRIPTION
       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.

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

       -i conf_file
	      Starts Siril with	the specified configuration file.

       -f, --format
	      Prints  all  supported input image formats, depending on the li-
	      braries 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_com-
	      mands.in and /tmp/siril_commands.out.

       -r input_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  ex-
	      ternal program with the mkfifo(1)	command.

       -w output_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.

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

       -s script_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 op-
	      tion 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.

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

       /usr/local/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.
