Hello, consider the following snippet:
EXTENSION=png INPUT_FILES=*.$EXTENSION If there are for example 3 input files, an echo delivers: echo $INPUT_FILES --> '01.png 02.png 03.png' No we change the EXTENSION: EXTENSION=jpg Now, in a dir without jpg files the following happens: INPUT_FILES=*.$EXTENSION echo $INPUT_FILES --> '*.jpg' instead of the empty string. Is there any way I can optain an empty string? I would like to test on the zeroness of INPUT_FILES. Best regards, Francky Leyn
