56The

58utility deletes any prefix ending with the last slash
59.Ql \&/
60character present in
61.Ar string
62(after first stripping trailing slashes),

65if given.
66The
67.Ar suffix
68is not stripped if it is identical to the remaining characters in
69.Ar string .
70The resulting filename is written to the standard output.
71A non-existent suffix is ignored.
72If
73.Fl a
74is specified, then every argument is treated as a
75.Ar string
76as if
77.Nm
78were invoked with just one argument.
79If
80.Fl s
81is specified, then the
82.Ar suffix
83is taken as its argument, and all other arguments are treated as a
84.Ar string .
