All the programs in Gnuastro share a set of common behavior mainly to do with user interaction to facilitate their usage. The most basic is how you can configure each program to do what you want: define the input, change parameter/option values, or identify the output. All Gnuastro programs can also read your desired configuration from pre-defined or user-specified files so you don’t have to specify all the (sometimes numerous) parameters on the command-line each time you run a program. These files define the “default” program behavior in each directory, for each user, or on each system. In other cases, some programs can greatly benefit from the many threads available in modern CPUs, so here we’ll also discuss how you can get the most out of your hardware. Among some other issues, we will also discuss how you can get immediate and distraction-free (without taking your hands off the keyboard!) help, or access to this whole book, on the command-line.
