YAD offers the ability to use a GUI way of specifying files in a dialog. However, when it comes to multiple file names as well as file names containing spaces, an extra level of complexity has to be dealt with.

No matter how a group of files is obtained, their names – or entire paths – must be stored for processing. As a structure for such data, BASH offers simply indexed arrays (there are also others). BASH creates an array whenever a variable assignment is created in the form ARRAY=( E lemente) . The individual elements of the array are accessed in the form ${ARRAY[INDEX]} . The INDEX starts at zero and automatically ends with the number of the
