In man dash the statement comes after the list of modifications: In the parameter expansions shown previously, use of the colon in the format results in a test for a parameter that is unset or null; omission of the colon results in a test for a parameter that is only unset. If there would be written ":" instead of "colon" i might have passed the brain agility test. Have a nice day :) Thomas
