Gnuastro’s programs are customized through the standard Unix-like command-line environment and GNU style command-line options. Both are very common in many Unix-like operating system programs. In Arguments and options we’ll start with the difference between arguments and options and elaborate on the GNU style of options. Afterwards, in Common options, we’ll go into the detailed list of all the options that are common to all the programs in Gnuastro.
|• Arguments and options||Different ways to specify inputs and configuration.|
|• Common options||Options that are shared between all programs.|
|• Standard input||Using output of another program as input.|
