A handy feature of Gnuastro is that all program names start with ast
.
This will allow your command-line processor to easily list and auto-complete Gnuastro’s programs for you.
Try typing the following command (press TAB key when you see <TAB>
) to see the list:
$ ast<TAB><TAB>
Any program that starts with ast
(including all Gnuastro programs) will be shown.
By choosing the subsequent characters of your desired program and pressing <TAB><TAB> again, the list will narrow down and the program name will auto-complete once your input characters are unambiguous.
In short, you often do not need to type the full name of the program you want to run.
