مثال على استعمال التابع fnmatch:
File.fnmatch('cat', 'cat') #=> true # match entire string
File.fnmatch('cat', 'category') #=> false # only match partial string
File.fnmatch('c{at,ub}s', 'cats') #=> false # { } isn't supported by default
File.fnmatch('c{at,ub}s', 'cats', File::FNM_EXTGLOB) #=> true # { } is supported on FNM_EXTGLOB
File.fnmatch('c?t', 'cat') #=> true # '?' match only 1 character
File.fnmatch('c??t', 'cat') #=> false # ditto
File.fnmatch('c*', 'cats') #=> true # '*' match 0 or more characters
File.fnmatch('c*t', 'c/a/b/t') #=> true # ditto
File.fnmatch('ca[a-z]', 'cat') #=> true # inclusive bracket expression
File.fnmatch('ca[^t]', 'cat') #=> false # exclusive bracket expression ('^' or '!')
File.fnmatch('cat', 'CAT') #=> false # case sensitive
File.fnmatch('cat', 'CAT', File::FNM_CASEFOLD) #=> true # case insensitive
File.fnmatch('?', '/', File::FNM_PATHNAME) #=> false # wildcard doesn't match '/' on FNM_PATHNAME
File.fnmatch('*', '/', File::FNM_PATHNAME) #=> false # ditto
File.fnmatch('[/]', '/', File::FNM_PATHNAME) #=> false # ditto
File.fnmatch('\?', '?') #=> true # escaped wildcard becomes ordinary
File.fnmatch('\a', 'a') #=> true # escaped ordinary remains ordinary
File.fnmatch('\a', '\a', File::FNM_NOESCAPE) #=> true # FNM_NOESCAPE makes '\' ordinary
File.fnmatch('[\?]', '?') #=> true # can escape inside bracket expression
File.fnmatch('*', '.profile') #=> false # wildcard doesn't match leading
File.fnmatch('*', '.profile', File::FNM_DOTMATCH) #=> true # period by default.
File.fnmatch('.*', '.profile') #=> true
rbfiles = '**' '/' '*.rb' # you don't have to do like this. just write in single string.
File.fnmatch(rbfiles, 'main.rb') #=> false
File.fnmatch(rbfiles, './main.rb') #=> false
File.fnmatch(rbfiles, 'lib/song.rb') #=> true
File.fnmatch('**.rb', 'main.rb') #=> true
File.fnmatch('**.rb', './main.rb') #=> false
File.fnmatch('**.rb', 'lib/song.rb') #=> true
File.fnmatch('*', 'dave/.profile') #=> true
pattern = '*' '/' '*'
File.fnmatch(pattern, 'dave/.profile', File::FNM_PATHNAME) #=> false
File.fnmatch(pattern, 'dave/.profile', File::FNM_PATHNAME | File::FNM_DOTMATCH) #=> true
pattern = '**' '/' 'foo'
File.fnmatch(pattern, 'a/b/c/foo', File::FNM_PATHNAME) #=> true
File.fnmatch(pattern, '/a/b/c/foo', File::FNM_PATHNAME) #=> true
File.fnmatch(pattern, 'c:/a/b/c/foo', File::FNM_PATHNAME) #=> true
File.fnmatch(pattern, 'a/.b/c/foo', File::FNM_PATHNAME) #=> false
File.fnmatch(pattern, 'a/.b/c/foo', File::FNM_PATHNAME | File::FNM_DOTMATCH) #=> true
