SERVICES(5)                 BSD File Formats Manual                SERVICES(5)

NAME
     services -- service name database

DESCRIPTION
     The services file contains information regarding the known services
     available in the DARPA Internet.  For each service, a single line should
     be present with the following information:

           official service name
           port number
           protocol name
           aliases

     Items are separated by any number of blanks and/or tab characters.  The
     port number and protocol name are considered a single item; a slash ('/')
     is used to separate the port and protocol (e.g., ``512/tcp'').

     A hash mark ('#') indicates the beginning of a comment; subsequent char-
     acters up to the end of the line are not interpreted by the routines
     which search the file.

     Service names may contain any printable character other than a field
     delimiter, newline, or comment character.

FILES
     /etc/services

SEE ALSO
     getservent(3)

HISTORY
     The services file format appeared in 4.2BSD.

BUGS
     A name server should be used instead of a static file.  Lines in
     /etc/services are limited to BUFSIZ characters (currently 1024).  Longer
     lines will be ignored.
