DESCRIPTION

16       The services file  is a local source of information regarding each ser‐
17       vice available through the Internet. The services file can be  used  in
18       conjunction  with  or  instead of other services sources, including the
19       NIS maps "services.byname" and the NIS+ table "services."  Programs use
20       the getservbyname(3SOCKET) routines to access this information.
21
22
23       The  services  file  contains an entry for each service. Each entry has
24       the form:
25
26         service-name   port/protocol   aliases
27
28
29       service-name     This is the official Internet service name.
30
31
32       port/protocol    This field is composed of the port number and protocol
33                        through  which  the service is provided, for instance,
34                        512/tcp.
35
36
37       aliases          This is a list of alternate names by which the service
38                        might be requested.
39
40
41
42       Fields can be separated by any number of SPACE and/or TAB characters. A
43       number sign (#) indicates the beginning of a  comment;  any  characters
44       that  follow  the  comment  character up to the end of the line are not
45       interpreted by routines which search the file.
46
47
48       Service names may contain any printable character other  than  a  field
49       delimiter, a NEWLINE, or a comment character.
50
51
52       Any  changes  to a port assignment do not affect the actual port regis‐
53       tration of the service.
