[:foo:] names character classes, and a character class is an element inside a bracket expression. The correct spelling is [[:blank:]]: From (gawk) Bracket Expressions: > A character class is only valid in a regexp _inside_ the brackets > of a bracket expression. Character classes consist of ‘[:’, a keyword > denoting the class, and ‘:]’. *note Table 3.1: table-char-classes. > lists the character classes defined by the POSIX standard. -- Arsen Arsenović
