Class: IO::Path §

(IO::Path) method basename §

Defined as:

method basename(IO::Path:D:)

Returns the basename part of the path object, which is the name of the filesystem object itself that is referenced by the path.

"docs/README.pod".IO.basename.say; # OUTPUT: «README.pod␤» 
"/tmp/".IO.basename.say;           # OUTPUT: «tmp␤»

Note that in IO::Spec::Win32 semantics, the basename of a Windows share is \, not the name of the share itself:

IO::Path::Win32.new('//server/share').basename.say; # OUTPUT: «\␤»
