Returns true if self points to a mountpoint.
Predicate method for root directories. Returns true if the pathname consists of consecutive slashes.
It doesn’t access the filesystem. So it may return false for some pathnames which points to roots such as /usr/...
Predicate method for testing whether a path is absolute.
It returns true if the pathname begins with a slash.
p = Pathname.new('/im/sure') p.absolute? #=> true p = Pathname.new('not/so/sure') p.absolute? #=> false
Iterates over and yields a new Pathname object for each element in the given path in descending order.
Pathname.new('/path/to/some/file.rb').descend {|v| p v} #<Pathname:/> #<Pathname:/path> #<Pathname:/path/to> #<Pathname:/path/to/some> #<Pathname:/path/to/some/file.rb> Pathname.new('path/to/some/file.rb').descend {|v| p v} #<Pathname:path> #<Pathname:path/to> #<Pathname:path/to/some> #<Pathname:path/to/some/file.rb>
Returns an Enumerator if no block was given.
enum = Pathname.new("/usr/bin/ruby").descend
# ... do stuff ...
enum.each { |e| ... }
# yields Pathnames /, /usr, /usr/bin, and /usr/bin/ruby.
It doesn’t access the filesystem.
Iterates over and yields a new Pathname object for each element in the given path in ascending order.
Pathname.new('/path/to/some/file.rb').ascend {|v| p v} #<Pathname:/path/to/some/file.rb> #<Pathname:/path/to/some> #<Pathname:/path/to> #<Pathname:/path> #<Pathname:/> Pathname.new('path/to/some/file.rb').ascend {|v| p v} #<Pathname:path/to/some/file.rb> #<Pathname:path/to/some> #<Pathname:path/to> #<Pathname:path>
Returns an Enumerator if no block was given.
enum = Pathname.new("/usr/bin/ruby").ascend
# ... do stuff ...
enum.each { |e| ... }
# yields Pathnames /usr/bin/ruby, /usr/bin, /usr, and /.
It doesn’t access the filesystem.
Appends a pathname fragment to self to produce a new Pathname object.
p1 = Pathname.new("/usr") # Pathname:/usr p2 = p1 + "bin/ruby" # Pathname:/usr/bin/ruby p3 = p1 + "/etc/passwd" # Pathname:/etc/passwd # / is aliased to +. p4 = p1 / "bin/ruby" # Pathname:/usr/bin/ruby p5 = p1 / "/etc/passwd" # Pathname:/etc/passwd
This method doesn’t access the file system; it is pure string manipulation.
Joins the given pathnames onto self to create a new Pathname object.
path0 = Pathname.new("/usr") # Pathname:/usr path0 = path0.join("bin/ruby") # Pathname:/usr/bin/ruby # is the same as path1 = Pathname.new("/usr") + "bin/ruby" # Pathname:/usr/bin/ruby path0 == path1 #=> true
Returns the children of the directory (files and subdirectories, not recursive) as an array of Pathname objects.
By default, the returned pathnames will have enough information to access the files. If you set with_directory to false, then the returned pathnames will contain the filename only.
For example:
pn = Pathname("/usr/lib/ruby/1.8")
pn.children
# -> [ Pathname:/usr/lib/ruby/1.8/English.rb,
Pathname:/usr/lib/ruby/1.8/Env.rb,
Pathname:/usr/lib/ruby/1.8/abbrev.rb, ... ]
pn.children(false)
# -> [ Pathname:English.rb, Pathname:Env.rb, Pathname:abbrev.rb, ... ]
Note that the results never contain the entries . and .. in the directory because they are not children.
Iterates over the directory tree in a depth first manner, yielding a Pathname for each file under “this” directory.
Returns an Enumerator if no block is given.
Since it is implemented by the standard library module Find, Find.prune can be used to control the traversal.
If self is ., yielded pathnames begin with a filename in the current directory, not ./.
See Find.find
Recursively deletes a directory, including all directories beneath it.
See FileUtils.rm_r
Create a Pathname object from the given String (or String-like object). If path contains a NULL character (\0), an ArgumentError is raised.
Compare this pathname with other. The comparison is string-based. Be aware that two different paths (foo.txt and ./foo.txt) can refer to the same file.

Compare this pathname with other. The comparison is string-based. Be aware that two different paths (foo.txt and ./foo.txt) can refer to the same file.
Provides a case-sensitive comparison operator for pathnames.
Pathname.new('/usr') <=> Pathname.new('/usr/bin') #=> -1 Pathname.new('/usr/bin') <=> Pathname.new('/usr/bin') #=> 0 Pathname.new('/usr/bin') <=> Pathname.new('/USR/BIN') #=> 1
It will return -1, 0 or 1 depending on the value of the left argument relative to the right argument. Or it will return nil if the arguments are not comparable.
Return a pathname which is substituted by String#sub.
path1 = Pathname.new('/usr/bin/perl') path1.sub('perl', 'ruby') #=> #<Pathname:/usr/bin/ruby>
Returns all the bytes from the file, or the first N if specified.
