Does anybody know how to use ?(pattern)? Or @(pattern)? Or any of them
except !(pattern)? If you do an internet search, the man page is always
blithely quoted, but only !(pattern) is ever demostrated...
I wonder if the others even work?
?(pattern-list)
Matches zero or one occurrence of the given patterns
*(pattern-list)
Matches zero or more occurrences of the given patterns
+(pattern-list)
Matches one or more occurrences of the given patterns
@(pattern-list)
Matches one of the given patterns
!(pattern-list)
Matches anything except one of the given patterns
$ ls -d ?(*clean*|vim)
ciho-clean clean vim
(not that I can think of an application - purely academic)
